This study aims to determine the prevalence and characterize ESBLs and carbapenamase producing Enterobactericeae. Method: A cross-sectional study was carried out in Gertrude’s Children’s Hospital, Nairobi. 238 urine samples were collected from patients with urinary symptoms attending the outpatient department within the period 2020-2021. The urine were examined macroscopically and microscopically. Identification and antimicrobial susceptibility testing were done using VITEK® 2 Compact system (BioMérieux). Double disc synergy test and modified hodge tests were done as confirmatory tests for ESBLs and Carbapenamase phenotypes respectively. Polymerase Chain Reaction was used for the detection of blaCTX-M, blaTEM, blaSHV, blaKPC and blaOXA-48 genes. Results: From the 238 children sampled the prevalence of UTI caused by Enterobactericeae was 22.3%. The Enterobacteriaceae species isolated were Escherichia coli (84.9%), Klebsiella pneumoniae (5.66%), Proteus mirabillis (5.66%), Enterobacter aerogenes (1.89%) and Morganella morganii (1.89%). The isolated species were resistant to ampicillin. Meropenem had the highest susceptibility. Only E. coli species had the ESBLs (26.4%) and carbapenamase (1.9%) phenotypes. 100% had BlaCTX-M while 50% had blaTEM resistant gene. There was a significant association (p Conclusion: Ampicillin resistance resulted to use of alternative drugs and Meropenem was the drug of choice where increased resistance to the recommended drugs was noted. Further research on resistant genes is recommended.展开更多

The urine cytobacteriological examination is the key test for its diagnosis. This work aims to Evaluate the prevalence of urinary tract infection at the Microbiology Laboratory of the University Hospital Mohamed VI in Tangier and to highlight its epidemiological and bacteriological characteristics. It was a descriptive study with retrospective data collection which took place from January 2021 to June 2022, at the Microbiology Laboratory of the university hospital Mohamed VI in Tangier. It covered all urine cytobacteriological examinations (ECBU) during the study period. We identified 77 cases of urinary tract infections out of 300 requests for (ECBU), that is a positivity rate of 25 %. The mean age was 55 years. The male gender was predominant. The epidemiological profile of the isolated strains was dominated by Enterobacteriaceae 81 %, followed by Gram-positive cocci 11 % and non-fermenting gram-negative bacteria 8 %. The main bacteria responsible for urinary tract infections in order of frequency: Escherichia coli 42 %, Klebsiella pneumoniae 20 %, Enterobacter cloacae 9 %, Staphylococcus aureus 6 %, Pseudomonas aeruginosa 5 % and Acinetobacter baumannii 3%. Most of the analyzed organisms showed resistance, especially to the beta-lactam antibiotic;the enterobacteria strains isolated had revealed resistance to amoxicillin: 74%, to amoxicillin-clavulanic acid in 40% of cases, and to third-generation cephalosporins in 24%. In terms of resistance mechanisms, 11 % of the Enterobacteriaceae were extended-spectrum β-lactamase producers and 9 % of the specimens were identified as carbapenemase producers. Of the Staphylococcus aureus strains isolated, 75% were resistant to meticillin. The Glycopeptides and linezolid were the most active molecules on these isolated strains. 15% of Enterococcus species isolated in our laboratory were resistant to glycopeptides (vancomycin and teicoplanin).展开更多

However, the increasing global development of antibiotic resistance necessitates updating diagnostic techniques to ensure higher sensitivity and specificity, especially with advancements in science and medicine. This study aimed to evaluate the prevalence of UTIs and antibiotic resistance profiles through urine culture, as well as to identify Klebsiella pneumoniae, Klebsiella oxytoca, and Acinetobacter spp. in urine samples using a molecular approach with multiplex real-time PCR. From May 3 to July 25, 2023, at the Pietro Annigoni Biomolecular Research Center (CERBA) and Saint Camille Hospital of Ouagadougou (HOSCO), 209 urine samples collected from patients with suspected UTIs were analyzed using both urine culture and multiplex real-time PCR. Among the 209 patients, 52.15% were male and 47.85% female, with an average age of 46.87 ± 21.33 years. Urine cultures revealed an overall UTI prevalence of 23.44%, with a prevalence of 8.13% in men versus 15.31% in women (P = 0.023). The bacterial prevalence rates were as follows: Escherichia coli (12.92%), Klebsiella spp. (7.18%), Enterobacter cloacae (1.44%), Staphylococcus aureus (0.96%), and other bacteria. Klebsiella spp. demonstrated 100% resistance to Amoxicillin and Amoxicillin/Clavulanic Acid, while Escherichia coli showed 96.2% and 65.4% resistance to Amoxicillin and Amoxicillin/Clavulanic Acid, respectively. PCR analysis of the target bacteria revealed mono-infection prevalence rates of Klebsiella pneumoniae (10.39%), Klebsiella oxytoca (7.79%), and Acinetobacter spp. (7.79%), along with a co-infection prevalence rate of Klebsiella pneumoniae/Acinetobacter spp. (1.30%). This study demonstrated that PCR, with its high sensitivity and specificity, could effectively distinguish Klebsiella pneumoniae from Klebsiella oxytoca and detect Acinetobacter spp. in less than 24 hours—something urine culture alone could not achieve. The relative ease of automating urine PCR testing, combined with its diagnostic accuracy and rapid turnaround time, makes it a valuable addition to modern medical practice for the laboratory diagnosis of UTIs.展开更多

The aim of our work was to establish the epidemiological and bacteriological profile of UTIs in children and then to study the sensitivity of the bacterial strains isolated to antibiotics. Materials and methods: This is a retrospective descriptive study over 3 years (2019-2022), including all cytobacteriological examination of urine (CBEU), performed in children aged 3 months to 14 years, admitted and treated for UTI, in the pediatric emergency department of Mohamed VI University Hospital. Results: A total of 239 children were included in our study. The mean age was 26 months. The sex ratio was 1.08. Escherichia coli was the most isolated bacterial strain in 79% of samples. The tested strains showed a high level of sensitivity to susceptibility rate toward amikacin (91%) and ciprofloxacin (100%) and whereas the level of resistance was high to the most current recommended antibiotics, mainly beta-lactams. Management was based, in severe forms of pyelonephritis, dual antibiotic therapy based on Third-generation cephalosporins combined with gentamycin. Favorable outcome was noted in 94% of children. Conclusion: Awareness-raising on the proper use of antibiotics, issuing national recommendations for the treatment of urinary tract infections in order to standardize therapeutic regimens is strongly recommended. Effective control of these infections requires a global prevention strategy that implies close collaboration between epidemiologists, clinicians, bacteriologists, hygienists and the health care team.展开更多

The recent introduction of endoscopy of the upper urinary tract represents a major advance in our department. The aim was to contribute to the study of the treatment of lithiasis of the upper urinary tract in Conakry and to report on our initial experience of ureteroscopy in Conakry. Methodology: This is a prospective descriptive study lasting one year, from January 1 to December 31, 2022, carried out at the Urology Department of the Ignace Deen National Hospital and at the PERCHIN Urological Clinic. The study included all patients treated surgically for lithiasis of the upper urinary tract who met the selection criteria. Results: The study included 57 patients. The mean age was 30 years, with extremes of 20 and 73 years;the most represented age group was 31 to 40 years, followed by 20 to 30 years with 29.9% and 26.3% respectively. Males predominated in 36 cases (63.15%), with a M/F sex ratio of 1.71. Left-sided renal colic was the most common, at 75.43% (n=43), and right-sided renal colic at 40.35%, associated with digestive signs at 43.85%. 77.19% had normal creatinine levels before surgery, versus 22.81% with elevated creatinine levels, i.e. 15.78% improvement in renal function after surgery. Urinary tract infection was found in 47.36%, and Escherichia coli in 31.57%, followed by staphylococcus aureus in 8.77%. Overall, 82.45% of patients had organic damage to the kidneys or ureters. Right ureterohydronephrosis was noted in 56.14%, followed by left hydronephrosis in 26.32%. Open surgery was predominant in 52.63% of cases, with endoscopic surgery (URS) accounting for a significant 47.36% during the study period. The endoscopic treatment used was laser ureteroscopy. In our study, 73.68% underwent drainage of the upper excretory tract, including 64.91% with a JJ catheter. The average length of stay was 07 days, with extremes of 02 and 28 days, and 81.4% of patients who underwent URS had a length of stay of less than 4 days. Conventional surgery had the highest complication rate (14.28%). The stone free rate for the two surgical treatment methods (open and endoscopic surgery) was 73% and 92.59%.展开更多

This may result in obstruction of the lower urinary tract causing storage and voiding symptoms. Methods: This was a prospective cross-sectional study from August 2020 to July 2021, to evaluate the characteristic of patients presenting to the Tamale Teaching Hospital with lower urinary tract symptoms secondary to BPH. Results: The median age at presentation with LUTS secondary to BPH is 68.88 ± 11.10 years with an average prostate volume of 70 g. The average time of presentation to the hospital is 5 months, mostly with moderate to severe symptoms. Correlation between Prostate volume (PV) and age yielded a positive relationship;however, this was not statistically significant, (r = 0.028, p-value = 0.747). There was a significant positive relationship between PV and the IPSS score, (r = 0.334, p-value Conclusion: Our patients with symptomatic BPH present at age 60 years and above, with nearly all of them presenting with moderate to severe LUTS.展开更多

This study sought to determine the relationship(s) between pregnancy trimesters, UTIs and changes in progesterone levels among pregnant women. Materials and Methods: The study was conducted in 2016 at Moi Teaching and Referral Hospital (MTRH) antenatal clinic which is a referral facility that attends to patients from most Counties in western region of Kenya. A cross-sectional study design was used to collect blood and urine specimens from 78 participants. Blood was used to determine progesterone levels using ELISA technique and urine cultures with bacterial colony counts ≥ 10<sup>5</sup> were appropriately identified to species level. Trimester periods and participants’ demographic information were obtained using a structured questionnaire. Results: Culture results showed that the most abundant bacterial species isolated in urine from the pregnant women was Escherechia coli (63.7%). The more affected age-group was women between 30 - 39 years during trimester three, suggesting that bacterial colonization of genital track occurred more frequently in older compared to the younger women. There was an exponential increase in progesterone levels among the pregnant women during trimester three compared to other trimesters, although these increases occurred independent of age. However, high levels of progesterone among pregnant women in third trimester corresponded with increased number of E. coli causing UTI. Conclusion: The results showed that progesterone levels increase with trimester and the most prevalent bacteria associated with this was E. coli even though age and increase in progesterone levels had no significant impact on E. coli infection.展开更多

Objective: To describe the epidemiological, clinical and biological profile of urinary tract infection in the internal medicine unit of the Fousseyni Daou hospital in Kayes. Methodology: It was a descriptive and cross-sectional study with retrospective data collection which took place from January 1 to December 31, 2020 at the Internal Medicine Unit of the Fousseyni Daou Hospital in Kayes. It covered all outpatients and hospitalized patients presenting with a urinary tract infection during the study period. Results: We identified 79 cases of urinary tract infection out of 145 requests for ECBU, that is a positivity rate of 53.10% and out of a total of 1883 admissions that is a hospital prevalence of 4.19%. The age groups of 36 to 45 years and 46 to 55 years were more represented in 28 cases (35.44%) and 25 cases (31.64%) with an average age of 45 years ± 10. The female sex was predominant, 42 cases (53.16%) with a sex ratio of 0.88. Housewives were more represented 28 cases (34.44%). The majority of patients resided in rural areas 49 cases (62.03%). The history was dominated by the following pathologies: hypertension 48.10%, diabetes 36.70% and gastropathy 30.37%. The main clinical manifestations were: Urinary burning 67 cases (84.81%), Dysuria 65 cases (82.27%), Pelvic pain 59 cases (74.68%), Fever 57 cases (72.15%). The epidemiological profile of the isolated strains was dominated by enterobacteriaceae, followed by gram-positive cocci and gram-negative bacilli. The main bacteria responsible for urinary tract infections in order of frequency: Escherichia coli (45.56%), Klebsiella pneumoniae (11.39%), Pseudomonas aeruginosa (8.86%), Staphylococcus aureus (7.59%), Streptococcus sp (6.33%), Enterobacter cloacae (3.79%), Acinetobacter sp (3.79%). The study of the susceptibility and resistance profiles of the isolated strains showed significant sensitivity of enterobacteriaceae to colistin and resistance to amoxicillin and to the amoxicillin + clavulanic acid combination. Conclusion: Urinary tract infections are a major public health problem since they are responsible for significant morbidity and mortality and a high cost of care. Knowledge of the epidemiological-clinical and bacteriological profile of these infections is essential for efficient management.展开更多

ESBLs are bacteria with enzymes that make them resistant to many antibiotics, posing a significant health challenge. This study aims to determine the characteristics of ESBL-producing bacteria causing UTIs in expectant women. Methodology: A self-administered survey was carried out;300 expectant women were recruited using a random sampling method. A questionnaire was used to collect socio-demographic information. Urine samples were collected in sterile universal bottles and processed at the JKUAT Zoology laboratory. Urine samples were analyzed using urinalysis, microscopy, culture, and sensitivity testing. ESBL-producing bacteria were identified phenotypically using the double-disc synergy test (DDST) and genotyped for specific resistant genes using PCR. Results: UTI prevalence was 32.7% (98/300). UTI was significantly associated with the history of previous UTI (OR = 0.84, p = 0.02) and multigravida (OR = 0.14 p = 0.01). UTI was common in women aged between 28-37 years in their second trimester. Bacteria isolated were E. coli 57.1% (56/98), S. aureus 21.4% (21/98) K. pneumonia 11.2% (11/98) and Proteus spp 10.4% (10/98). Bacteria antibiotic resistance patterns were E. coli-tetracycline (91.1%), sulfamethoxazole (55.4%), cefotaxime (53.4%) and augmentin (53.4%). S. aureus-sulfamethozaxole (100%) and augmentin (71.4%), K. pneumoniae-sulfame-thoxazole (72.2%) cefotaxime (63.6%), chloramphenicol and tetracycline (54.5%). Proteus spp: tetracycline (100%), nitrofurantoin (90%), cefotaxime and chloramphenicol (50%). The proportion of ESBLs bacterial producers was 37.6% (29/77) and 44.8% (13/29) possessed ESBLs resistant genes;Bla CTX-M 53.8% (7/13), Bla SHV and Bla TEM 23.1% (3/13) each, Bla OXA (0%) was not detected. Conclusion: The study revealed a high proportion of ESBLs producing bacteria responsible for UTI in expectant women. ESBLs screening, routine culture and sensitivity testing will guide on proper management and empirical treatment of UTI patients thus reducing multi-drug resistance.展开更多

There is however paucity of studies that compares the trifecta outcome between screen detected and patients presenting with lower urinary symptoms with localized prostate cancer after radical prostatectomy. This study compares the trifecta outcomes between these two groups after an open retropubic radical prostatectomy. Methodology: This is a retrospective study, on the trifecta outcomes (urinary continence, erectile function, and cancer control) of consecutive patients that had open radical retropubic prostatectomy for localized prostate cancer by a single surgeon. Patients were grouped into screen detected and presentation with lower urinary symptoms or retention of urine. The parameters considered were the age of the patients, the total prostate specific antigen (tPSA) at presentation, the clinical T stage, the Gleason score of prostate biopsies, the risk categories using the D’Amico risk groups and the trifecta outcomes after the procedure. Results: In all, 119 patients met the criteria for inclusion. The median follow up was 63.5 months (range 12 - 156 months). Of these 40.3% of the patients were diagnosed through screening with elevated PSA while 59.7% had presented with symptoms of lower urinary tract obstruction. The mean age for the patients was 60.8 ± 6.5 years, median PSA 12.6 ng/ml (IQR 8.6 - 19.7) and median prostate weight of 50.0 (IQR 40.0 - 60 g). The urinary continence rate after the procedure was 93.3%, erection rate of 81.5%, cancer control rate of 71.4% and trifecta achieved in 57.1%. Comparing the screening and the symptomatic cases, the urinary continence rate was 91.7% vrs 94.3%;erectile function rate was 79.2% vrs 83.1%;cancer control 68.8% vrs 73.2% and trifecta achieved in 58.3% vrs 56.3%. There was no statistically significant difference between the two groups in terms of urinary continence p = 0.564, erection function p = 0.588, cancer control p = 0.595, and achieving trifecta p = 0.829. Conclusion: Patients with localized prostate cancer presenting with lower urinary symptoms compared to screen detected patients have similar outcomes in terms of urinary Continence, erectile function, cancer control and trifecta after open radical retropubic prostatectomy.展开更多

However, in resource-limited countries, accessibility to CBEU remains hindered by cost and availability. This study aims to assess the utility of the Urinary Dipstick Test (UDT) in diagnosing UTIs among hospitalized patients in the context of limited resources. Methods: A cross-sectional study was conducted from February to May 2019, encompassing hospitalized patients who underwent CBEU at the bacteriology unit of Sour? Sanou University Hospital. UDT and CBEU were concurrently performed, and UDT’s analytical and diagnostic performance was evaluated against CBEU, considered the gold standard. Results: A total of 274 CBEU requests were registered, involving 274 patients (159 males) with a mean age of 45.8 ± 21.3 years (ranging from 1 to 90 years). UTI was confirmed in 90 patients, yielding a frequency of 32.85%. The UTI bacteriological profile was dominated by Enterobacteriaceae (75.23%), primarily Escherichia coli (60.55%). Nitrite and Leukocytes were positive in 54 (19.8%) and 157 (53.6%) of the samples tested. Among patients with confirmed UTI, Nitrite, and Leukocytes were positive in 30 (33%) and 71 (79%) patients respectively. UDT demonstrated variable performance based on nitrite and leukocyte combination: Sensitivity (57%-82%), Specificity (7%-98%), Positive Predictive Value (PPV) (43%-57%), Negative Predictive Value (NPV) (43%-67%). UDT performed slightly better in women (NPV = 88%) and inpatients without urinary catheters (NPV = 75% and PPV = 80%). Conclusion: This study underscores UDT’s potential utility in excluding UTIs among women, younger patients, and inpatients without urinary catheters, albeit with limited confidence. The UDT emerges as a complementary tool for UTI screening, particularly in resource-limited settings.展开更多

With the availability of Covid-19 vaccines, clinical practice has stepped gradually towards its everyday routine. The clinician, however, needs to address such concerns as “Can Covid-19 present with urinary tract symptoms predominantly?”, “Can the urinary tract develop long-term Covid-19 symptoms?”, “Can Covid-19 vaccines/drug therapy cause male infertility?” Methods: This mini-review of the current literature has been carried out by searching the Pubmed database. Results and Conclusions: Our literature review suggests that there is insufficient evidence to conclude a significant impact on the urinary tract from Covid-19 infection. There is supporting evidence that mRNA anti-SARS-CoV-2 vaccines are safe for male gonads. Research to further support these conclusions is required.展开更多
文摘Objective:To investigate the evolving patterns of antimicrobial resistance against beta-lactam antibiotics in Escherichia coli isolates from urinary tract infection patients in Vietnam,covering the period from 2005 to 2022.Methods:29 Descriptive studies published between 2010 and 2022 in English and Vietnamese were included in the analysis.Data on resistance rates to beta-lactam antibiotics,including cephalosporins and carbapenems,were extracted and analyzed.Weighted pooled resistance rates were calculated using random-effects models.Annual trends in resistance were assessed using linear regression analysis.Results:Among the beta-lactam antibiotics studied,Escherichia coli exhibited varying levels of resistance,with cephalosporins showing higher resistance rates compared to carbapenems.Weighted pooled resistance rates were 66%for cefotaxime,65%for ceftriaxone,54%for ceftazidime,and 56%for cefepime.In contrast,carbapenems demonstrated lower resistance rates,with weighted pooled resistance rates ranging from 3%to 4%for meropenem,ertapenem,and imipenem.Resistance rates were also observed for amoxicillin/clavulanate(35%),ticarcillin/clavulanate(26%),and piperacillin/tazobactam(12%).Significant annual increases in resistance were noted for imipenem(0.56%,P<0.001).Conclusions:This study highlights the critical issue of antimicrobial resistance in urinary tract infections in Vietnam and emphasizes the importance of prudent antibiotic use and the regular monitoring of resistance patterns.These insights are useful for guiding healthcare professionals in optimizing treatment strategies and for policymakers in formulating evidence-based clinical guidelines to combat antibiotic resistance effectively.
文摘Introduction: Enterobacteriaceae causing urinary tract infections (UTI) have developed resistance to the commonly used antibiotics due to emergence of Extended Spectrum Beta-Lactamases (ESBLs) and Carbapenamase producing Enterobactericeae which are a public health problem worldwide. This study aims to determine the prevalence and characterize ESBLs and carbapenamase producing Enterobactericeae. Method: A cross-sectional study was carried out in Gertrude’s Children’s Hospital, Nairobi. 238 urine samples were collected from patients with urinary symptoms attending the outpatient department within the period 2020-2021. The urine were examined macroscopically and microscopically. Identification and antimicrobial susceptibility testing were done using VITEK® 2 Compact system (BioMérieux). Double disc synergy test and modified hodge tests were done as confirmatory tests for ESBLs and Carbapenamase phenotypes respectively. Polymerase Chain Reaction was used for the detection of blaCTX-M, blaTEM, blaSHV, blaKPC and blaOXA-48 genes. Results: From the 238 children sampled the prevalence of UTI caused by Enterobactericeae was 22.3%. The Enterobacteriaceae species isolated were Escherichia coli (84.9%), Klebsiella pneumoniae (5.66%), Proteus mirabillis (5.66%), Enterobacter aerogenes (1.89%) and Morganella morganii (1.89%). The isolated species were resistant to ampicillin. Meropenem had the highest susceptibility. Only E. coli species had the ESBLs (26.4%) and carbapenamase (1.9%) phenotypes. 100% had BlaCTX-M while 50% had blaTEM resistant gene. There was a significant association (p Conclusion: Ampicillin resistance resulted to use of alternative drugs and Meropenem was the drug of choice where increased resistance to the recommended drugs was noted. Further research on resistant genes is recommended.
文摘Urinary tract infection is one of the most common bacterial infections in humans. The urine cytobacteriological examination is the key test for its diagnosis. This work aims to Evaluate the prevalence of urinary tract infection at the Microbiology Laboratory of the University Hospital Mohamed VI in Tangier and to highlight its epidemiological and bacteriological characteristics. It was a descriptive study with retrospective data collection which took place from January 2021 to June 2022, at the Microbiology Laboratory of the university hospital Mohamed VI in Tangier. It covered all urine cytobacteriological examinations (ECBU) during the study period. We identified 77 cases of urinary tract infections out of 300 requests for (ECBU), that is a positivity rate of 25 %. The mean age was 55 years. The male gender was predominant. The epidemiological profile of the isolated strains was dominated by Enterobacteriaceae 81 %, followed by Gram-positive cocci 11 % and non-fermenting gram-negative bacteria 8 %. The main bacteria responsible for urinary tract infections in order of frequency: Escherichia coli 42 %, Klebsiella pneumoniae 20 %, Enterobacter cloacae 9 %, Staphylococcus aureus 6 %, Pseudomonas aeruginosa 5 % and Acinetobacter baumannii 3%. Most of the analyzed organisms showed resistance, especially to the beta-lactam antibiotic;the enterobacteria strains isolated had revealed resistance to amoxicillin: 74%, to amoxicillin-clavulanic acid in 40% of cases, and to third-generation cephalosporins in 24%. In terms of resistance mechanisms, 11 % of the Enterobacteriaceae were extended-spectrum β-lactamase producers and 9 % of the specimens were identified as carbapenemase producers. Of the Staphylococcus aureus strains isolated, 75% were resistant to meticillin. The Glycopeptides and linezolid were the most active molecules on these isolated strains. 15% of Enterococcus species isolated in our laboratory were resistant to glycopeptides (vancomycin and teicoplanin).
文摘Urinary tract infections (UTIs) caused by uropathogens are a significant public health problem, and their treatment primarily relies on antibiotic therapy. However, the increasing global development of antibiotic resistance necessitates updating diagnostic techniques to ensure higher sensitivity and specificity, especially with advancements in science and medicine. This study aimed to evaluate the prevalence of UTIs and antibiotic resistance profiles through urine culture, as well as to identify Klebsiella pneumoniae, Klebsiella oxytoca, and Acinetobacter spp. in urine samples using a molecular approach with multiplex real-time PCR. From May 3 to July 25, 2023, at the Pietro Annigoni Biomolecular Research Center (CERBA) and Saint Camille Hospital of Ouagadougou (HOSCO), 209 urine samples collected from patients with suspected UTIs were analyzed using both urine culture and multiplex real-time PCR. Among the 209 patients, 52.15% were male and 47.85% female, with an average age of 46.87 ± 21.33 years. Urine cultures revealed an overall UTI prevalence of 23.44%, with a prevalence of 8.13% in men versus 15.31% in women (P = 0.023). The bacterial prevalence rates were as follows: Escherichia coli (12.92%), Klebsiella spp. (7.18%), Enterobacter cloacae (1.44%), Staphylococcus aureus (0.96%), and other bacteria. Klebsiella spp. demonstrated 100% resistance to Amoxicillin and Amoxicillin/Clavulanic Acid, while Escherichia coli showed 96.2% and 65.4% resistance to Amoxicillin and Amoxicillin/Clavulanic Acid, respectively. PCR analysis of the target bacteria revealed mono-infection prevalence rates of Klebsiella pneumoniae (10.39%), Klebsiella oxytoca (7.79%), and Acinetobacter spp. (7.79%), along with a co-infection prevalence rate of Klebsiella pneumoniae/Acinetobacter spp. (1.30%). This study demonstrated that PCR, with its high sensitivity and specificity, could effectively distinguish Klebsiella pneumoniae from Klebsiella oxytoca and detect Acinetobacter spp. in less than 24 hours—something urine culture alone could not achieve. The relative ease of automating urine PCR testing, combined with its diagnostic accuracy and rapid turnaround time, makes it a valuable addition to modern medical practice for the laboratory diagnosis of UTIs.
文摘Background: Urinary tract infection (UTI) is one of the most frequent bacterial infections in pediatrics. The aim of our work was to establish the epidemiological and bacteriological profile of UTIs in children and then to study the sensitivity of the bacterial strains isolated to antibiotics. Materials and methods: This is a retrospective descriptive study over 3 years (2019-2022), including all cytobacteriological examination of urine (CBEU), performed in children aged 3 months to 14 years, admitted and treated for UTI, in the pediatric emergency department of Mohamed VI University Hospital. Results: A total of 239 children were included in our study. The mean age was 26 months. The sex ratio was 1.08. Escherichia coli was the most isolated bacterial strain in 79% of samples. The tested strains showed a high level of sensitivity to susceptibility rate toward amikacin (91%) and ciprofloxacin (100%) and whereas the level of resistance was high to the most current recommended antibiotics, mainly beta-lactams. Management was based, in severe forms of pyelonephritis, dual antibiotic therapy based on Third-generation cephalosporins combined with gentamycin. Favorable outcome was noted in 94% of children. Conclusion: Awareness-raising on the proper use of antibiotics, issuing national recommendations for the treatment of urinary tract infections in order to standardize therapeutic regimens is strongly recommended. Effective control of these infections requires a global prevention strategy that implies close collaboration between epidemiologists, clinicians, bacteriologists, hygienists and the health care team.
文摘Introduction: The management of urinary lithiasis in our settings has long been conventional surgery. The recent introduction of endoscopy of the upper urinary tract represents a major advance in our department. The aim was to contribute to the study of the treatment of lithiasis of the upper urinary tract in Conakry and to report on our initial experience of ureteroscopy in Conakry. Methodology: This is a prospective descriptive study lasting one year, from January 1 to December 31, 2022, carried out at the Urology Department of the Ignace Deen National Hospital and at the PERCHIN Urological Clinic. The study included all patients treated surgically for lithiasis of the upper urinary tract who met the selection criteria. Results: The study included 57 patients. The mean age was 30 years, with extremes of 20 and 73 years;the most represented age group was 31 to 40 years, followed by 20 to 30 years with 29.9% and 26.3% respectively. Males predominated in 36 cases (63.15%), with a M/F sex ratio of 1.71. Left-sided renal colic was the most common, at 75.43% (n=43), and right-sided renal colic at 40.35%, associated with digestive signs at 43.85%. 77.19% had normal creatinine levels before surgery, versus 22.81% with elevated creatinine levels, i.e. 15.78% improvement in renal function after surgery. Urinary tract infection was found in 47.36%, and Escherichia coli in 31.57%, followed by staphylococcus aureus in 8.77%. Overall, 82.45% of patients had organic damage to the kidneys or ureters. Right ureterohydronephrosis was noted in 56.14%, followed by left hydronephrosis in 26.32%. Open surgery was predominant in 52.63% of cases, with endoscopic surgery (URS) accounting for a significant 47.36% during the study period. The endoscopic treatment used was laser ureteroscopy. In our study, 73.68% underwent drainage of the upper excretory tract, including 64.91% with a JJ catheter. The average length of stay was 07 days, with extremes of 02 and 28 days, and 81.4% of patients who underwent URS had a length of stay of less than 4 days. Conventional surgery had the highest complication rate (14.28%). The stone free rate for the two surgical treatment methods (open and endoscopic surgery) was 73% and 92.59%.
文摘Objective:To analyze the effect of arterial embolism(AE)in patients with massive urinary system bleeding(MBUS).Methods:From September 2018 to September 2023,175 cases of MBUS patients in the emergency department of the hospital were randomly selected and divided into groups according to the length of stay.Among them,85 cases(September 2018–September 2020)underwent bladder irrigation treatment with aluminum potassium sulfate solution through a catheter(Group A),and 90 cases(October 2020–September 2023)underwent AE treatment(Group B).The treatment effects of the two groups were compared.Results:The treatment effectiveness of Group B is higher than that of Group A(P<0.05).The urinary hemoglobin level of Group B is lower than that of Group A at 1,6,12,and 24 hours after treatment(P<0.05).Among the 90 cases treated with AE,7 cases had a fever,with body temperatures ranging from 37.3°C to 38.9℃,with a mean temperature of 38.2±0.3℃.Four cases experienced local pain,nausea,and vomiting,while two cases of intra-iliac AE showed transient buttock pain.These patients with adverse reactions were treated symptomatically for 7 days.All patients recovered after treatment.Intravenous urography of 87 patients in June showed that the renal pelvis and calyces were in good condition,the renal function returned to normal,and the blood urea nitrogen and blood creatinine test results were within the normal range.After 1 year of follow-up,no hypertension occurred.Conclusion:AE treats MBUS patients in the emergency department with remarkable efficacy.It has the advantages of less damage to the body,rapid hemostasis,high safety,and maximum preservation of organ function.
文摘Background: Benign prostatic hyperplasia (BPH) is the proliferation of the stromal and epithelial cells of the prostate gland, resulting in an increase in its size. This may result in obstruction of the lower urinary tract causing storage and voiding symptoms. Methods: This was a prospective cross-sectional study from August 2020 to July 2021, to evaluate the characteristic of patients presenting to the Tamale Teaching Hospital with lower urinary tract symptoms secondary to BPH. Results: The median age at presentation with LUTS secondary to BPH is 68.88 ± 11.10 years with an average prostate volume of 70 g. The average time of presentation to the hospital is 5 months, mostly with moderate to severe symptoms. Correlation between Prostate volume (PV) and age yielded a positive relationship;however, this was not statistically significant, (r = 0.028, p-value = 0.747). There was a significant positive relationship between PV and the IPSS score, (r = 0.334, p-value Conclusion: Our patients with symptomatic BPH present at age 60 years and above, with nearly all of them presenting with moderate to severe LUTS.
文摘Background and Aims: Urinary tract infections (UTIs) are common among pregnant women and major predisposing factors for pyelonephritis linked to obstetrical complications including preterm labour and low infants’ birth weights. This study sought to determine the relationship(s) between pregnancy trimesters, UTIs and changes in progesterone levels among pregnant women. Materials and Methods: The study was conducted in 2016 at Moi Teaching and Referral Hospital (MTRH) antenatal clinic which is a referral facility that attends to patients from most Counties in western region of Kenya. A cross-sectional study design was used to collect blood and urine specimens from 78 participants. Blood was used to determine progesterone levels using ELISA technique and urine cultures with bacterial colony counts ≥ 10<sup>5</sup> were appropriately identified to species level. Trimester periods and participants’ demographic information were obtained using a structured questionnaire. Results: Culture results showed that the most abundant bacterial species isolated in urine from the pregnant women was Escherechia coli (63.7%). The more affected age-group was women between 30 - 39 years during trimester three, suggesting that bacterial colonization of genital track occurred more frequently in older compared to the younger women. There was an exponential increase in progesterone levels among the pregnant women during trimester three compared to other trimesters, although these increases occurred independent of age. However, high levels of progesterone among pregnant women in third trimester corresponded with increased number of E. coli causing UTI. Conclusion: The results showed that progesterone levels increase with trimester and the most prevalent bacteria associated with this was E. coli even though age and increase in progesterone levels had no significant impact on E. coli infection.
文摘Objective To determine the prevalence of lower urinary tract symptoms(LUTS)and their severity population in Jordan.Methods This cross-sectional survey was conducted using a paper-based survey between August and September in 2019.The study was carried out in the health care centers or hospitals in three different regions of Jordan:North(Irbid and Jarash),Middle(Amman,Madaba,Salt,and Zarqa),and South(Karak and Aqaba).Results To estimate the prevalence of LUTS,two definitions were used,including the first definition(presence of any LUTS regardless of the degree of severity)and the second definition(presence of any LUTS that occurs half the time or more).According to the first definition,1038(89.9%)reported LUTS(male:47.3%,female:52.7%),while 763(66.1%)reported LUTS according to the second definition(male:45.6%,female:54.4%).According to the International Prostate Symptom Score characterization,73.9%had nocturia and 62.9%reported daytime increased frequency.Conclusion LUTS are highly prevalent among the Jordanian population,and more than half of them have nocturia or daytime increased frequency as most frequently reported symptoms.

文摘Objective To describe whether or not there are gender differences in lower urinary tract symptoms(LUTS)prevalence and risk factors in community-dwelling older Chinese Americans.Methods We performed a secondary analysis of a prospective cross-sectional population-based survey of Chinese Americans aged 60 years and older between January 2011 and December 2013 in English,Mandarin,Cantonese,Taishanese,or Teochew.A clinical review of systems was used to assess LUTS,which included urinary frequency,urgency,burning and/or pain,blood in urine,and urinary incontinence.Results Of the total 3157 people queried,42%were men and 58%were women.More men reported LUTS compared to women(32.9%vs.28.6%,p=0.01).In a multivariable analysis,female gender(adjusted odds ratio[aOR]0.60,95%confidence interval[CI]0.49-0.73),being married(aOR 0.79,95%CI 0.65-0.97),and smoking(aOR 0.66,95%CI 0.49-0.88)were found to be protective,while traditional Chinese medicine use(aOR 1.51,95%CI 1.28-1.78),heart disease(aOR 1.54,95%CI 1.24-1.91),and anxiety(aOR 1.69,95%CI 1.25-2.28)were most strongly associated with increased odds of LUTS.When examining genders separately,being married was found to be protective only in women.Meanwhile,unique factors found in men were hypertension,heart disease,and practice of Tai Chi.Conclusion In this large population-based study,LUTS were more prevalent in older Chinese American men than women.We also found gender-specific factors that influenced the odds of reporting LUTS;however,traditional Chinese medicine use was the only factor that was shared by both genders.Future longitudinal investigations are needed to elucidate these underlying mechanisms to provide evidence-based and culture-specific guidelines for this rapidly growing population.
文摘BACKGROUND Urinary sepsis is frequently seen in patients with diabetes mellitus(DM)complicated with upper urinary tract calculi(UUTCs).Currently,the known risk factors of urinary sepsis are not uniform.AIM To analyze the risk factors of concurrent urinary sepsis in patients with DM complicated with UUTCs by logistic regression.METHODS We retrospectively analyzed 384 patients with DM complicated with UUTCs treated in People’s Hospital of Jincheng between February 2018 and May 2022.The patients were screened according to the inclusion and exclusion criteria,and 204 patients were enrolled.The patients were assigned to an occurrence group(n=78)and a nonoccurrence group(n=126).Logistic regression was adopted to analyze the risk factors for urinary sepsis,and a risk prediction model was established.RESULTS Gender,age,history of lumbago and abdominal pain,operation time,urine leukocytes(U-LEU)and urine glucose(U-GLU)were independent risk factors for patients with concurrent urinary sepsis(P<0.05).Risk score=0.794×gender+0.941×age+0.901×history of lumbago and abdominal pain-1.071×operation time+1.972×U-LEU+1.541×U-GLU.The occurrence group had notably higher risk scores than the nonoccurrence group(P<0.0001).The area under the curve of risk score for forecasting concurrent urinary sepsis in patients was 0.801,with specificity of 73.07%,sensitivity of 79.36%and Youden index of 52.44%.CONCLUSION Sex,age,history of lumbar and abdominal pain,operation time,ULEU and UGLU are independent risk factors for urogenic sepsis in diabetic patients with UUTC.

文摘Introduction: Urinary tract infection is one of the most frequent public health problems in the world and concerns all ages. Objective: To describe the epidemiological, clinical and biological profile of urinary tract infection in the internal medicine unit of the Fousseyni Daou hospital in Kayes. Methodology: It was a descriptive and cross-sectional study with retrospective data collection which took place from January 1 to December 31, 2020 at the Internal Medicine Unit of the Fousseyni Daou Hospital in Kayes. It covered all outpatients and hospitalized patients presenting with a urinary tract infection during the study period. Results: We identified 79 cases of urinary tract infection out of 145 requests for ECBU, that is a positivity rate of 53.10% and out of a total of 1883 admissions that is a hospital prevalence of 4.19%. The age groups of 36 to 45 years and 46 to 55 years were more represented in 28 cases (35.44%) and 25 cases (31.64%) with an average age of 45 years ± 10. The female sex was predominant, 42 cases (53.16%) with a sex ratio of 0.88. Housewives were more represented 28 cases (34.44%). The majority of patients resided in rural areas 49 cases (62.03%). The history was dominated by the following pathologies: hypertension 48.10%, diabetes 36.70% and gastropathy 30.37%. The main clinical manifestations were: Urinary burning 67 cases (84.81%), Dysuria 65 cases (82.27%), Pelvic pain 59 cases (74.68%), Fever 57 cases (72.15%). The epidemiological profile of the isolated strains was dominated by enterobacteriaceae, followed by gram-positive cocci and gram-negative bacilli. The main bacteria responsible for urinary tract infections in order of frequency: Escherichia coli (45.56%), Klebsiella pneumoniae (11.39%), Pseudomonas aeruginosa (8.86%), Staphylococcus aureus (7.59%), Streptococcus sp (6.33%), Enterobacter cloacae (3.79%), Acinetobacter sp (3.79%). The study of the susceptibility and resistance profiles of the isolated strains showed significant sensitivity of enterobacteriaceae to colistin and resistance to amoxicillin and to the amoxicillin + clavulanic acid combination. Conclusion: Urinary tract infections are a major public health problem since they are responsible for significant morbidity and mortality and a high cost of care. Knowledge of the epidemiological-clinical and bacteriological profile of these infections is essential for efficient management.
文摘Background: Urinary tract infection (UTI) is a bacterial infection affecting males and females but is more prevalent in expectant women. ESBLs are bacteria with enzymes that make them resistant to many antibiotics, posing a significant health challenge. This study aims to determine the characteristics of ESBL-producing bacteria causing UTIs in expectant women. Methodology: A self-administered survey was carried out;300 expectant women were recruited using a random sampling method. A questionnaire was used to collect socio-demographic information. Urine samples were collected in sterile universal bottles and processed at the JKUAT Zoology laboratory. Urine samples were analyzed using urinalysis, microscopy, culture, and sensitivity testing. ESBL-producing bacteria were identified phenotypically using the double-disc synergy test (DDST) and genotyped for specific resistant genes using PCR. Results: UTI prevalence was 32.7% (98/300). UTI was significantly associated with the history of previous UTI (OR = 0.84, p = 0.02) and multigravida (OR = 0.14 p = 0.01). UTI was common in women aged between 28-37 years in their second trimester. Bacteria isolated were E. coli 57.1% (56/98), S. aureus 21.4% (21/98) K. pneumonia 11.2% (11/98) and Proteus spp 10.4% (10/98). Bacteria antibiotic resistance patterns were E. coli-tetracycline (91.1%), sulfamethoxazole (55.4%), cefotaxime (53.4%) and augmentin (53.4%). S. aureus-sulfamethozaxole (100%) and augmentin (71.4%), K. pneumoniae-sulfame-thoxazole (72.2%) cefotaxime (63.6%), chloramphenicol and tetracycline (54.5%). Proteus spp: tetracycline (100%), nitrofurantoin (90%), cefotaxime and chloramphenicol (50%). The proportion of ESBLs bacterial producers was 37.6% (29/77) and 44.8% (13/29) possessed ESBLs resistant genes;Bla CTX-M 53.8% (7/13), Bla SHV and Bla TEM 23.1% (3/13) each, Bla OXA (0%) was not detected. Conclusion: The study revealed a high proportion of ESBLs producing bacteria responsible for UTI in expectant women. ESBLs screening, routine culture and sensitivity testing will guide on proper management and empirical treatment of UTI patients thus reducing multi-drug resistance.
文摘Background: Many studies have reported on trifecta outcomes after radical prostatectomy. There is however paucity of studies that compares the trifecta outcome between screen detected and patients presenting with lower urinary symptoms with localized prostate cancer after radical prostatectomy. This study compares the trifecta outcomes between these two groups after an open retropubic radical prostatectomy. Methodology: This is a retrospective study, on the trifecta outcomes (urinary continence, erectile function, and cancer control) of consecutive patients that had open radical retropubic prostatectomy for localized prostate cancer by a single surgeon. Patients were grouped into screen detected and presentation with lower urinary symptoms or retention of urine. The parameters considered were the age of the patients, the total prostate specific antigen (tPSA) at presentation, the clinical T stage, the Gleason score of prostate biopsies, the risk categories using the D’Amico risk groups and the trifecta outcomes after the procedure. Results: In all, 119 patients met the criteria for inclusion. The median follow up was 63.5 months (range 12 - 156 months). Of these 40.3% of the patients were diagnosed through screening with elevated PSA while 59.7% had presented with symptoms of lower urinary tract obstruction. The mean age for the patients was 60.8 ± 6.5 years, median PSA 12.6 ng/ml (IQR 8.6 - 19.7) and median prostate weight of 50.0 (IQR 40.0 - 60 g). The urinary continence rate after the procedure was 93.3%, erection rate of 81.5%, cancer control rate of 71.4% and trifecta achieved in 57.1%. Comparing the screening and the symptomatic cases, the urinary continence rate was 91.7% vrs 94.3%;erectile function rate was 79.2% vrs 83.1%;cancer control 68.8% vrs 73.2% and trifecta achieved in 58.3% vrs 56.3%. There was no statistically significant difference between the two groups in terms of urinary continence p = 0.564, erection function p = 0.588, cancer control p = 0.595, and achieving trifecta p = 0.829. Conclusion: Patients with localized prostate cancer presenting with lower urinary symptoms compared to screen detected patients have similar outcomes in terms of urinary Continence, erectile function, cancer control and trifecta after open radical retropubic prostatectomy.
文摘BACKGROUND Ureteral injury is a known complication of hysterectomies.Recent studies have attempted to correlate surgeon volume and experience with incidence of urinary tract injuries during hysterectomies.Some studies have reported that as surgeon volume increases,urinary tract injury rates decrease.To our knowledge,no studies have assessed the relationship between surgeon subspecialty and the rate of urinary tract injury rates during minimally invasive hysterectomy.AIM To determine the incidence of urinary tract injury between urogynecologists,gynecologic oncologists,and general gynecologists.METHODS The study took place from January 1,2016 to December 1,2021 at a large comm-unity hospital in Detroit,Michigan.We conducted a retrospective chart review of adult patients who underwent minimally invasive hysterectomy.After we identified eligible patients,the surgeon subspecialty was identified and the surgeon’s volume per year was calculated.Patient demographics,medical history,physician-dictated operative reports,and all hospital visits postoperatively were reviewed.RESULTS Urologic injury occurred in four patients(2%)in the general gynecologist group,in one patient(1%)in the gynecologic oncologist group,and in one patient(1%)in the urogynecologist group.When comparing high and low-volume surgeons,there was no statistically significant difference in urinary tract injury(1%vs 2%)or bowel injury(1%vs 0%).There were more complications in the low-volume group vs the high-volume group excluding urinary tract,bowel,or major vessel injury.High-volume surgeons had four(1%)patients with a complication and low-volume surgeons had 12(4%)patients with a complication(P=0.04).CONCLUSION Our study demonstrated that there was no difference in the urinary tract injury rate in general gynecologists vs subspecialists,however our study was underpowered.
文摘Background: Urinary Tract Infection (UTI), a prevalent bacterial infection in adults, heavily relies on cytobacteriological examination of urine (CBEU) for diagnosis. However, in resource-limited countries, accessibility to CBEU remains hindered by cost and availability. This study aims to assess the utility of the Urinary Dipstick Test (UDT) in diagnosing UTIs among hospitalized patients in the context of limited resources. Methods: A cross-sectional study was conducted from February to May 2019, encompassing hospitalized patients who underwent CBEU at the bacteriology unit of Sour? Sanou University Hospital. UDT and CBEU were concurrently performed, and UDT’s analytical and diagnostic performance was evaluated against CBEU, considered the gold standard. Results: A total of 274 CBEU requests were registered, involving 274 patients (159 males) with a mean age of 45.8 ± 21.3 years (ranging from 1 to 90 years). UTI was confirmed in 90 patients, yielding a frequency of 32.85%. The UTI bacteriological profile was dominated by Enterobacteriaceae (75.23%), primarily Escherichia coli (60.55%). Nitrite and Leukocytes were positive in 54 (19.8%) and 157 (53.6%) of the samples tested. Among patients with confirmed UTI, Nitrite, and Leukocytes were positive in 30 (33%) and 71 (79%) patients respectively. UDT demonstrated variable performance based on nitrite and leukocyte combination: Sensitivity (57%-82%), Specificity (7%-98%), Positive Predictive Value (PPV) (43%-57%), Negative Predictive Value (NPV) (43%-67%). UDT performed slightly better in women (NPV = 88%) and inpatients without urinary catheters (NPV = 75% and PPV = 80%). Conclusion: This study underscores UDT’s potential utility in excluding UTIs among women, younger patients, and inpatients without urinary catheters, albeit with limited confidence. The UDT emerges as a complementary tool for UTI screening, particularly in resource-limited settings.
文摘Introduction and Objectives: Since its advent in 2019, Corona Virus Disease 19 (Covid-19) has changed everyday life in many unprecedented ways. With the availability of Covid-19 vaccines, clinical practice has stepped gradually towards its everyday routine. The clinician, however, needs to address such concerns as “Can Covid-19 present with urinary tract symptoms predominantly?”, “Can the urinary tract develop long-term Covid-19 symptoms?”, “Can Covid-19 vaccines/drug therapy cause male infertility?” Methods: This mini-review of the current literature has been carried out by searching the Pubmed database. Results and Conclusions: Our literature review suggests that there is insufficient evidence to conclude a significant impact on the urinary tract from Covid-19 infection. There is supporting evidence that mRNA anti-SARS-CoV-2 vaccines are safe for male gonads. Research to further support these conclusions is required.
