Patient and Methods: The study was conducted in Department of General Surgery in Maulana Azad Medical College, New Delhi. 60 men with proven clinical diagnosis of BPH of size 30 grams and less presenting with symptoms of bladder outlet obstruction (BOO) were randomised prospectively to undergo either of the two operative modalities. Preoperatively size of the prostate, symptom scoring (IPSS), peak flow rate (Qmax) were assessed. Postoperatively and during 4 months follow up the following data were collected—operative time, catheterisation period, hospital stay, blood loss, Qmax and IPSS. Results: Preoperative parameters in both the groups showed no statistically significant differences with respect to prostate size, Qmax and IPSS Scoring. At 4 months follow up Qmax increased from (6.35 ± 4.49) to (16.41 ± 2.28) in TURP group and (4.51 ± 3.57) to (15.95 ± 2.58) in BNI group. IPSS decreased from 18.70 to 5.7 in TURP group and 18.90 to 6.00 in BNI group. All differences were statistically significant. There was a statistically significant difference in operative time, blood loss, hospital stay, catheterisation timing favouring BNI. Conclusion: TURP and BNI are equally effective in providing symptomatic improvement. BNI has an upper hand in reference to operative time, hospital stay, duration of catheterisation and blood loss.展开更多

We hypothesized that the urinary level of BDNF could be a potential biomarker for lower urinary tract symptoms（LUTS） in patients with BPH. Totally, 76 patients with BPH-caused LUTS and 32 male control subjects without BPH were enrolled. International Prostate Symptom Score（IPSS） was applied to assess the symptom severity of LUTS. Urodynamic tests were performed for the diagnosis of underlying detrusor overactivity（DO） in the patients with BPH. Urine samples were collected from all subjects. Urinary BDNF levels were measured using enzyme-linked immunosorbent assays and normalized by urinary creatinine（Cr） levels. Seventy-six BPH patients were divided into moderate LUTS group（n=51, 720） according to the IPSS. Of the 76 BPH patients, DO was present in 34（44.7%） according to the urodynamic test. The urinary BDNF/Cr levels were significantly higher in BPH patients with moderate LUTS（8.29±3.635, P〈0.0001） and severe LUTS（11.8±6.44, P〈0.0001） than normal controls（1.71±0.555）. Patients with severe LUTS tended to have higher urinary BDNF/Cr levels than patients with moderate LUTS（11.8±6.44 vs. 8.29±3.635, P=0.000）. The conditions of BPH with LUTS correlated with elevated urinary BDNF levels, and urinary BDNF levels were even higher in BPH-DO patients. The results of this study have provided evidence to suggest that urinary BDNF level test could evaluate the severity of LUTS in BPH patients, and BDNF level can be used as a biomarker展开更多

Acupuncture and moxibustion are used in the clinic in China for improving LUTS symptoms due to BPH. However,there is no evidence to suggest which is the best option. We compared the efficacy of acupuncture and moxibustion to provide evidence for clinical decision-making.Methods: PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wan Fang Data, and VIP databases were searched from inception to July 2020 to identify the randomized controlled trials(RCTs) of acupuncture and moxibustion for LUTS due to BPH. Two researchers filtered studies and extracted the information independently. This study conducted a network meta-analysis using the Bayesian random method. The interventions ranking was evaluated using the surface under the cumulative ranking curve(SUCRA).Results: We finally included 40 studies comprising 10 treating therapies and 3,655 patients with LUTS caused by BPH. In terms of the International Prostate Symptom Score, maximum urinary flow rate, and quality of life, electroacupuncture(EA) [MD =-3.6,95% credible interval(CrI)(-5.5,-1.8), very low certainty of evidence;MD = 2.2, 95% CrI(1.1, 3.3), low certainty of evidence;MD =-1.3, 95% CrI(-2.2,-0.43), very low certainty of the evidence] may be consistently the optimal treatment compared with other interventions, with SUCRA values of 84%, 81%, and 89%, respectively.Conclusions: Of all treatments, EA may have the best efficacy with fewer adverse events for LUTS due to BPH. The quality of evidence supporting this result is low to very low certainty of the evidence due to the limitations of primary studies;thus, more highquality RCTs are needed for further evidence.展开更多

METHODS: A comprehensive research was conducted to identify all publications relating to benign prostate hyperplasia and treatment with sildenafil, vardenafil and tadalafil. To assess the efficacy, the changes in total international prostate symptom score(IPSS), IPSS subscore including voiding, storage and quality of life(Qo L), Benign prostatic hyperplasia Impact Index(BII), maximum urinary flow rate(Qmax) and the International Index of Erectile Function(IIEF) were extracted. A meta-analytical technique was used for the analysis of integrated data from the included studies to evaluate the mean difference in the results. RESULTS: Total IPSS score, IIEF and BII showed a significant improvement in trials in which LUTS/BPH with or without erectile dysfunction(ED) were compared with the placebo. For LUTS/BPH, the mean differences of total IPSS score, IIEF and BII are-2.17, 4.88 and-0.43, P < 0.00001, respectively. For LUTS/BPH with comorbid ED, the mean difference are-1.97, 4.54 and-0.52, P < 0.00001, respectively. PDE5-Is appear to improve IPSS storage, voiding and Qo L subscore(mean difference =-0.71,-1.23 and-0.33, P < 0.00001, respectively). Although four doses of tadalafil(2.5, 5, 10 and 20 mg) failed to reach significance in Qmax(mean difference = 0.22, P = 0.10), the 5 mg dose of tadalafil significantly improved the Qmax(mean difference = 0.33, P = 0.03).CONCLUSION: PED5-Is demonstrated efficacy for improving LUTS in BPH patients with or without ED and could be considered to be the first line treatment for LUTS/BPH.展开更多

Therefore, we assessed the impact of this change on the patients, at a men’s health clinic, with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH). Material and Methods: Subjects were 100 men with BPH who had been taking tamsulosin 0.2 mg as needed for at least 3 months. The outcome measures were IPSS, AMS and IEFF5 scores and uroflowmetry. Tolerability was evaluated on by adverse events. Changes from baseline were assessed using the paired t-test. SPSS version 12.0 was used for statistical analysis, with p 0.05 considered significant. Results: The mean follow up of tamsulosin 0.2 and 0.4 mg were 20.23 and 10.56 months respectively. On switching from tamsulosin 0.2 to 0.4 mg, mean IPSS score improved from 15.54 ± SD 1.25 to 14.13 ± SD 1.09 (p = 0.034), Q max 15.91 cm3/sec ± SD 1.36 to 16.69 cm3/sec ± SD 1.52 (p = 0.128), and nocturia 3.15 ± SD 0.32 to 2.68 ± SD 0.39 (p = 0.015), respectively. However IEFF-5 score and AMS score increased from14.78 ± SD 1.38 to 15.79 ± SD 1.03 (p = 0.0055) and 34.76 ± SD 2.76 to 33.21 ± SD 2.62 (p = 0.0853), respectively. Treatment-related adverse events of Tamsulosin 0.2 mg included dizziness (4%), postural hypotension (3%) and retrograde ejaculation (3%). Interestingly, no withdrawals resulted from adverse events during Tamsulosin 0.4 mg assessment. Conclusions: Switching to tamsulosin 0.4 mg improves LUTS. The change was well tolerated by the majority of patients. Increased symptoms scores of erectile dysfunction and aging male during the study may be due to increased age.展开更多

Although it is not a life-threatening condition, BPH has an adverse effect on a patient’s quality of life, as manifested in community and clinical trials. <strong>Aim:</strong> The aim of the study was the perception of patients in their symptomatology by comparing the place of residence and quality of life in living with HBP using the IPSS questionnaire. <strong>Materials and Methods:</strong> This was a prospectively designed study conducted at University Clinical Centre of Kosovo—Urology Clinic. The study was conducted from October 2020 to January 2021. The study in criteria was as follows: all patients who presented to the urology outpatient clinic with BPH, Lower Urinary Tract Symptoms (LUTS) and aged > 40 years. The exclusion criteria included the following cases: patients with uncontrolled diabetes (prostate-specific antigen > 4 ng/dL);patients with a history of transurethral resection of the prostate. <strong>Results:</strong> This study was carried out on 100 consecutive patients with HBP and LUTS attending. The largest proportion of patients 51% was in the 46 - 55 age group. Most patients were between 45 - 65 years of 51%. The largest number of them (52%) was with severe symptoms and 41% of them were with moderate symptoms. Comparing the three levels of IPSS and the quality of life of patients with HBP and LUTS, when asked how they would feel if they still had problems with urination, 22% said they felt upset, analyzing the categorization of patients according to IPSS: mild symptoms were Mean/SD (1.71. ± 1.113), moderate symptoms (2.9 ± 1.49) and severe symptoms (4.31 ± 1.27) p < 0.156. Statistical reliability of 64% p < 0.000 was in patients where they were interested in learning about any invasive option that would allow them to discontinue medication for LUTS. <strong>Conclusion:</strong> The IPSS is a valid instrument to assess the impact of BPH symptoms on health and quality of life due to urinary symptoms.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

To compare the efficacy and adverse events of Chinese herbal medicine alone or used adjuvantly with Western medications for BPH. Two independent reviewers searched the major electronic databases for randomized controlled trials comparing Chinese herbal medicine, either in single or adjuvant use with Western medication, with placebo or Western medication. Relevant journals and grey literature were also hand-searched. The outcome measures included changes in urological symptoms, urodynamic measures, prostate volume and adverse events. The frequency of commonly used herbs was also identified. Out of 13 922 identified citations of publications, 31 studies were included. Eleven studies with a Jadad score i〉 3 were selected for meta-analysis. Chinese herbal medicine was superior to Western medication in improving quality of life and reducing prostate volume. The frequency of adverse events in Chinese herbal medicine was similar to that of placebo and less than that of Western medication. The evidence is too weak to support the efficacy of Chinese herbal medicine for BPH due to the poor methodological quality and small number of trials included. The commonly used herbs identified here should provide insights for future clinical practice and research. Larger randomized controlled trials of better quality are needed to truly evaluate the efficacy of Chinese herbal medicine.展开更多

Fifty-three patients with LUTS （IPSS score 〉 7） whose maximum flow rate （Qmax） 〈 15 mL s-1 and PSA 〈 4 ng dL^-1 were enrolled in the study. Patients received doxazosin 4 nag once daily for 6 weeks. Subjective efficacy was assessed by IPSS, IPSS- Quality of Life （IPSS-QoL） for LUTS and efficacy was assessed by International Index of Erectile Function （IIEF） for erectile functions at baseline and sixth weeks. The objective efficacy was assessed by Q The patients were classified according to their self reported erectile status： group I had ED and group II did not have ED. At the endpoint, doxazosin significantly improved the total IPSS score （-7.7 ±6.1, P = 0.006）, IPSS-QoL score （-1.5 ± 1.5, P = 0.024） and Qmax （3.2 ± 4.6 mL s^-1, P = 0.002） over baseline. Mean decrease in IPSS and IPSS-QoL scores after the treatment period were 6.9 ＋ 6.4 （P 〈 0.001） and 0.95 4- 1.80 （P 〈 0.05） in group I, whereas 8.2 4- 5.8 （P 〈 0.001） and 1.9 4- 1.1 in group IX （P 〈 0.001）, respectively. Mean changes of Qmax values were 2.3 4- 3.3 mL s^-1 in group I （P 〈 0.05） and 3.7 4- 5.3 mL s-1 in group II （P 〈 0.001）. The improvement of IIEF-EF scores after the treatment period was only significant for group I. The efficacy of a-blocker therapy for LUTS was better by means of symptomatic relief for patients who did not have ED when compared with patients who had ED at baseline. However, slight improvement in erectile functions with a-blocker therapy was only seen in LUTS patients with ED.展开更多

Blood loss is one of the most common complications of TURP. Objective: To evaluate the effect of preoperative dutasteride on bleeding related to TURP in patients with BPH. Materials and Methods: This prospective interventional study was done in the department of urology, Dhaka Medical College Hospital, Dhaka, Bangladesh during the period of July 2016 to June 2017. A total of 70 cases of BPH planned for TURP were included in this study according to the statistical calculation. Patients were randomly allocated to control group A (TURP without dutasteride) and dutasteride group B (TURP with dutasteride). Each group consisted of 35 patients. Group B patients were treated with dutasteride 0.5 mg/day for 4 weeks before TURP. The main outcome of blood loss was evaluated in terms of reduction in serum hemoglobin (Hb) and hematocrit (Hct) levels, which were measured before and 24 hours after surgery. Data were analyzed and compared by statistical tests. Results: Comparison of outcome between groups shows that there was a significant difference in term of pre-post operative change of hemoglobin and hematocrit levels in the control group A compared to the dutasteride group B (Hb = 2.96 ± 0.80 gm/dl vs. 1.81 ± 0.71 gm/dl, respectively, p = 0.001;Hct = 11.20% ± 2.12% vs. 6.07% ± 2.02%, respectively, p = 0.02). A significant lower mean blood loss was observed in the dutasteride group compared to the control group. Conclusion: Preoperative dutasteride therapy reduces blood loss related to TURP in patients with BPH. This therapy can be practiced to reduce surgical bleeding associated with TURP.展开更多

A random number table was used to divide the participants into study and control groups(n = 70 per group). The study group underwent TUCBDP. The prostate resection surgical time, intraoperative blood loss, bladder irrigation time, catheter indwelling time, length of hospital stay, International Prostate Symptom Score(IPSS), maximum urine flow rate(Qmax), residual urine volume(RUV), changes in the International Erectile Function Score(ⅡEF-5) score, serum prostate-specific antigen(PSA), quality of life(QOL) score, and surgical complications were compared in both groups.RESULTS The operation time, intraoperative blood loss volume, bladder flushing time, urinary catheter indwelling time, and length of hospital stay were significantly lower in the study group than in the control group(P < 0.05). There were no significant differences in the IPSS, Qmax, and RUV measurements between the study and control groups(P > 0.05). However, at 3 mo post-surgery, the IPSS and RUV measurements were both lower(P < 0.05) and Qmax values were higher(P < 0.05) compared to the pre-surgery results in both groups. The ⅡEF-5 scores before and 3 mo after surgery were not significantly different between the study and control groups(P > 0.05). At 1 mo after surgery, the ⅡEF-5 score was higher in the study group than in the control group(P < 0.05). The serum PSA levels and QOL scores before treatment and at 1 and 3 mo after treatment were not significantly different between the study and control groups(P > 0.05). However, lower serum PSA levels and QOL scores were observed after 1 and 3 mo of treatment compared to pre-treatment levels in the study group(P < 0.05). The surgical complication rate of the study group(4.29%) was lower than that of the control group(12.86%;P < 0.05).CONCLUSION TUCBDP for BPH and transurethral resection of the prostate can achieve better results, but the former method is associated with less surgical trauma.展开更多

Lower urinary tract symptoms (LUTS) in...Benign prostatic hyperplasia (BPH) is a chronic condition that is more common in older men. BPH most commonly causes symptoms associated with LUTS and bladder outlet obstruction. Lower urinary tract symptoms (LUTS) in men with BPH are a major cause of reduced quality of life in older men. If bladder outlet obstruction persists for a longer period of time, the contractility and voiding capacity of the detrusor muscle will gradually be affected by the obstructive factors, eventually leading to a loss of compensatory phase, characterised by a reduced electrical stimulation response, replacement of bladder muscle tissue by connective tissue, and a possible increase in voiding pressure, but a decrease in contractility of the detrusor muscle. As BOO progresses, it eventually leads to permanent contractile dysfunction of the detrusor muscle. Therefore, early initiation of surgical treatment in patients who are not well controlled by medication can reduce the complications associated with prostate enlargement. With the rise of minimally invasive treatment and the complications of open surgery, minimally invasive treatment of BPH has attracted increasing attention. Various emerging minimally invasive surgical modalities are being developed in clinical practice, and more and more minimally invasive techniques and concepts are focusing on safety, improving quality of life and reducing long-term complications to meet the different needs of different patients. Transurethral resection of the prostate (TURP) is currently the “gold standard” of minimally invasive surgical treatment, but with concerns about post-operative complications, the search for safer and more effective minimally invasive surgical options has become even more important. In recent years, with the increasing clinical application of new minimally invasive techniques such as various lasers, interventional treatments and implantable devices, there are more options for minimally invasive treatment of BPH. This article provides a brief review of research advances in the minimally invasive treatment of benign prostatic hyperplasia, with a view to informing clinical decisions.展开更多

It is one of the most common diseases in ageing men. Its clinical presentations are dominated by lower urinary tract symptoms (LUTS). The therapeutic methods can be grouped into two options: the medical option and the surgical option in which prostate enucleation is found. In recent years many studies have reported the onset of urinary incontinence (UI) after prostate enucleation. The management of UI occurring after prostate enucleation is embarrassing for both the practitioner and the patient, and generates additional costs. Purpose: Cite the causes of UI after prostate enucleation for BPH, as well as ways to prevent the onset of UI after this surgery, specifically by the study of the vesicosphincteric system aimed at improving the technique of enucleation;our review will also deal with the therapeutic means of UI. Method: We retrieved studies from Science Direct, Wiley and Pubmed. Results: There are multiple etiologies of UI after prostate enucleation including urethral sphincter insufficiency (USI) and bladder dysfunction (BD). The management of UI after surgery could be conservative, surgical, or use new technologies. Urodynamic assessment before prostate enucleation for BPH is relevant. Conclusion: UI is a common post-operative complication of prostate enucleation. The study of the vesicosphincteric system leads us to believe that prostate enucleation for BPH, partially sparing the mucosa and the external urethral sphincter could decrease the incidence of UI after surgery.展开更多
文摘Benign prostatic hyperplasia(BPH)is a condition that greatly affects the quality of life of middle-aged and elderly men.Histopathologically,hyperplastic changes frequently occur in the prostate tissue of elderly men,the incidence of which has been reported to reach approximately 80% in men in their 70s.In clinical practice,approximately 25% of men with histologic BPH are assumed to experience lower urinary tract symptoms(LUTS)and receive some kind of treatment.In other words,there are some men with histologic BPH who do not exhibit LUTS.For that reason,many factors,such as the change in hormonal environment,the immune or autoimmune response,the alteration of gene expression,and so on,are thought to affect the onset and progression of LUTS in men with histologic BPH.One such factor that has long drawn attention is the presence of asymptomatic histological inflammation,which very often accompanies symptomatic BPH.Recent studies have suggested that asymptomatic histological inflammation causes repeated destruction,healing,and regeneration of the prostate tissue,leading to the enlargement of prostatic nodules,while at the same time causing stromal tissuepredominant remodeling of the prostate tissue,which can increase urination resistance and result in the condition changing from asymptomatic BPH to symptomatic BPH.In future,the biomolecular clarification of the significance of asymptomatic histological inflammation in the prostate tissue could help develop new treatment strategies for BPH accompanied by LUTS.
文摘Male patients with lower urinary tract symptoms(LUTS)and benign prostatic hyperplasia(BPH)are increasingly seen by family physicians worldwide due to ageing demographics.A systematic way to stratify patients who can be managed in the community and those who need to be referred to the urologist is thus very useful.Good history taking,physical examination,targeted blood or urine tests,and knowing the red flags for referral are the mainstay of stratifying these patients.Case selection is always key in clinical practice and in the setting of the family physician.The best patient to manage is one above 40 years of age,symptomatic with nocturia,slower stream and sensation of incomplete voiding,has a normal prostatespecific antigen level,no palpable bladder,and no haematuria or pyuria on the labstix.The roles of α blockers,5-α reductase inhibitors,and antibiotics in a primary care setting to manage this condition are also discussed.
文摘BACKGROUND Prostate artery embolization(PAE)is a promising minimally invasive therapy that improves lower urinary tract symptoms(LUTS)related to benign prostatic hyperplasia(BPH).Transurethral resection of the prostate(TURP)is the gold standard therapy for LUTS/BPH.AIM To evaluate the efficacy and safety of PAE vs TURP on LUTS related to BPH.METHODS A literature review was performed to identify all published articles on PAE vs TURP for LUTS/BPH.Sources included PubMed,Embase,Cochrane library databases,and Chinese databases before June 2022.A systematic review and meta-analysis were conducted.Outcome measurements were combined by calculating the mean difference with a 95%confidence interval.Statistical analysis was carried out using Review Manager 5.3.RESULTS Eleven studies involving 1070 participants were included.Compared with the TURP group,the PAE group had a similar effect on the International Index of Erectile Function(IPSS)score,Peak urinary flow rate(Qmax),postvoid residual volume(PVR),Prostate volume(PV),prostatic specific antigen(PSA),The International Index of Erectile Function short form(IIEF-5)scores,and erectile dysfunction during 24 mo follow-up.Lower quality of life(QoL)score,lower rate of retrograde ejaculation and shorter hospital stay in the PAE group.There was no participant death in either group.A higher proportion of haematuria,urinary incontinence and urinary stricture was identified in the TURP group.CONCLUSION PAE may be an appropriate option for elderly patients,patients who are not candidates for surgery,and patients who do not want to risk the potential adverse effects of TURP.Studies with large cases and long follow-up time are needed to validate results.
文摘Objective: To compare the efficacy of bladder neck incision (BNI) with transurethral resection of prostate (TURP) in the treatment of patients with urinary obstruction caused by benign prostatic hyperplasia (BPH) on the basis of short term follow up of 4 months. Patient and Methods: The study was conducted in Department of General Surgery in Maulana Azad Medical College, New Delhi. 60 men with proven clinical diagnosis of BPH of size 30 grams and less presenting with symptoms of bladder outlet obstruction (BOO) were randomised prospectively to undergo either of the two operative modalities. Preoperatively size of the prostate, symptom scoring (IPSS), peak flow rate (Qmax) were assessed. Postoperatively and during 4 months follow up the following data were collected—operative time, catheterisation period, hospital stay, blood loss, Qmax and IPSS. Results: Preoperative parameters in both the groups showed no statistically significant differences with respect to prostate size, Qmax and IPSS Scoring. At 4 months follow up Qmax increased from (6.35 ± 4.49) to (16.41 ± 2.28) in TURP group and (4.51 ± 3.57) to (15.95 ± 2.58) in BNI group. IPSS decreased from 18.70 to 5.7 in TURP group and 18.90 to 6.00 in BNI group. All differences were statistically significant. There was a statistically significant difference in operative time, blood loss, hospital stay, catheterisation timing favouring BNI. Conclusion: TURP and BNI are equally effective in providing symptomatic improvement. BNI has an upper hand in reference to operative time, hospital stay, duration of catheterisation and blood loss.

文摘Urinary brain-derived neurotrophic factor（BDNF）, an ubiquitous neurotrophin, was found to rise in patients with benign prostatic hyperplasia（BPH）. We hypothesized that the urinary level of BDNF could be a potential biomarker for lower urinary tract symptoms（LUTS） in patients with BPH. Totally, 76 patients with BPH-caused LUTS and 32 male control subjects without BPH were enrolled. International Prostate Symptom Score（IPSS） was applied to assess the symptom severity of LUTS. Urodynamic tests were performed for the diagnosis of underlying detrusor overactivity（DO） in the patients with BPH. Urine samples were collected from all subjects. Urinary BDNF levels were measured using enzyme-linked immunosorbent assays and normalized by urinary creatinine（Cr） levels. Seventy-six BPH patients were divided into moderate LUTS group（n=51, 720） according to the IPSS. Of the 76 BPH patients, DO was present in 34（44.7%） according to the urodynamic test. The urinary BDNF/Cr levels were significantly higher in BPH patients with moderate LUTS（8.29±3.635, P〈0.0001） and severe LUTS（11.8±6.44, P〈0.0001） than normal controls（1.71±0.555）. Patients with severe LUTS tended to have higher urinary BDNF/Cr levels than patients with moderate LUTS（11.8±6.44 vs. 8.29±3.635, P=0.000）. The conditions of BPH with LUTS correlated with elevated urinary BDNF levels, and urinary BDNF levels were even higher in BPH-DO patients. The results of this study have provided evidence to suggest that urinary BDNF level test could evaluate the severity of LUTS in BPH patients, and BDNF level can be used as a biomarker

文摘Objective: Lower urinary tract symptoms(LUTS) caused by benign prostatic hyperplasia(BPH) affect the quality of life of elderly individuals. Acupuncture and moxibustion are used in the clinic in China for improving LUTS symptoms due to BPH. However,there is no evidence to suggest which is the best option. We compared the efficacy of acupuncture and moxibustion to provide evidence for clinical decision-making.Methods: PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wan Fang Data, and VIP databases were searched from inception to July 2020 to identify the randomized controlled trials(RCTs) of acupuncture and moxibustion for LUTS due to BPH. Two researchers filtered studies and extracted the information independently. This study conducted a network meta-analysis using the Bayesian random method. The interventions ranking was evaluated using the surface under the cumulative ranking curve(SUCRA).Results: We finally included 40 studies comprising 10 treating therapies and 3,655 patients with LUTS caused by BPH. In terms of the International Prostate Symptom Score, maximum urinary flow rate, and quality of life, electroacupuncture(EA) [MD =-3.6,95% credible interval(CrI)(-5.5,-1.8), very low certainty of evidence;MD = 2.2, 95% CrI(1.1, 3.3), low certainty of evidence;MD =-1.3, 95% CrI(-2.2,-0.43), very low certainty of the evidence] may be consistently the optimal treatment compared with other interventions, with SUCRA values of 84%, 81%, and 89%, respectively.Conclusions: Of all treatments, EA may have the best efficacy with fewer adverse events for LUTS due to BPH. The quality of evidence supporting this result is low to very low certainty of the evidence due to the limitations of primary studies;thus, more highquality RCTs are needed for further evidence.

文摘AIM: To review the efficacy of phosphodiesterase type 5 inhibitors(PDE5-Is) in lower urinary tract symptoms(LUTS) suggestive of benign prostate hyperplasia(LUTS/BPH). METHODS: A comprehensive research was conducted to identify all publications relating to benign prostate hyperplasia and treatment with sildenafil, vardenafil and tadalafil. To assess the efficacy, the changes in total international prostate symptom score(IPSS), IPSS subscore including voiding, storage and quality of life(Qo L), Benign prostatic hyperplasia Impact Index(BII), maximum urinary flow rate(Qmax) and the International Index of Erectile Function(IIEF) were extracted. A meta-analytical technique was used for the analysis of integrated data from the included studies to evaluate the mean difference in the results. RESULTS: Total IPSS score, IIEF and BII showed a significant improvement in trials in which LUTS/BPH with or without erectile dysfunction(ED) were compared with the placebo. For LUTS/BPH, the mean differences of total IPSS score, IIEF and BII are-2.17, 4.88 and-0.43, P < 0.00001, respectively. For LUTS/BPH with comorbid ED, the mean difference are-1.97, 4.54 and-0.52, P < 0.00001, respectively. PDE5-Is appear to improve IPSS storage, voiding and Qo L subscore(mean difference =-0.71,-1.23 and-0.33, P < 0.00001, respectively). Although four doses of tadalafil(2.5, 5, 10 and 20 mg) failed to reach significance in Qmax(mean difference = 0.22, P = 0.10), the 5 mg dose of tadalafil significantly improved the Qmax(mean difference = 0.33, P = 0.03).CONCLUSION: PED5-Is demonstrated efficacy for improving LUTS in BPH patients with or without ED and could be considered to be the first line treatment for LUTS/BPH.
文摘Objectives: In 2010, tamsulosin 0.2 mg (OD) was withdrawn from Thailand and replaced with tamsulosin 0.4 mg (OD). Therefore, we assessed the impact of this change on the patients, at a men’s health clinic, with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH). Material and Methods: Subjects were 100 men with BPH who had been taking tamsulosin 0.2 mg as needed for at least 3 months. The outcome measures were IPSS, AMS and IEFF5 scores and uroflowmetry. Tolerability was evaluated on by adverse events. Changes from baseline were assessed using the paired t-test. SPSS version 12.0 was used for statistical analysis, with p 0.05 considered significant. Results: The mean follow up of tamsulosin 0.2 and 0.4 mg were 20.23 and 10.56 months respectively. On switching from tamsulosin 0.2 to 0.4 mg, mean IPSS score improved from 15.54 ± SD 1.25 to 14.13 ± SD 1.09 (p = 0.034), Q max 15.91 cm3/sec ± SD 1.36 to 16.69 cm3/sec ± SD 1.52 (p = 0.128), and nocturia 3.15 ± SD 0.32 to 2.68 ± SD 0.39 (p = 0.015), respectively. However IEFF-5 score and AMS score increased from14.78 ± SD 1.38 to 15.79 ± SD 1.03 (p = 0.0055) and 34.76 ± SD 2.76 to 33.21 ± SD 2.62 (p = 0.0853), respectively. Treatment-related adverse events of Tamsulosin 0.2 mg included dizziness (4%), postural hypotension (3%) and retrograde ejaculation (3%). Interestingly, no withdrawals resulted from adverse events during Tamsulosin 0.4 mg assessment. Conclusions: Switching to tamsulosin 0.4 mg improves LUTS. The change was well tolerated by the majority of patients. Increased symptoms scores of erectile dysfunction and aging male during the study may be due to increased age.
文摘<strong>Background:</strong> Benign prostatic hyperplasia (BPH) has been a major health problem for aging males because of its related symptoms and complications. Although it is not a life-threatening condition, BPH has an adverse effect on a patient’s quality of life, as manifested in community and clinical trials. <strong>Aim:</strong> The aim of the study was the perception of patients in their symptomatology by comparing the place of residence and quality of life in living with HBP using the IPSS questionnaire. <strong>Materials and Methods:</strong> This was a prospectively designed study conducted at University Clinical Centre of Kosovo—Urology Clinic. The study was conducted from October 2020 to January 2021. The study in criteria was as follows: all patients who presented to the urology outpatient clinic with BPH, Lower Urinary Tract Symptoms (LUTS) and aged > 40 years. The exclusion criteria included the following cases: patients with uncontrolled diabetes (prostate-specific antigen > 4 ng/dL);patients with a history of transurethral resection of the prostate. <strong>Results:</strong> This study was carried out on 100 consecutive patients with HBP and LUTS attending. The largest proportion of patients 51% was in the 46 - 55 age group. Most patients were between 45 - 65 years of 51%. The largest number of them (52%) was with severe symptoms and 41% of them were with moderate symptoms. Comparing the three levels of IPSS and the quality of life of patients with HBP and LUTS, when asked how they would feel if they still had problems with urination, 22% said they felt upset, analyzing the categorization of patients according to IPSS: mild symptoms were Mean/SD (1.71. ± 1.113), moderate symptoms (2.9 ± 1.49) and severe symptoms (4.31 ± 1.27) p < 0.156. Statistical reliability of 64% p < 0.000 was in patients where they were interested in learning about any invasive option that would allow them to discontinue medication for LUTS. <strong>Conclusion:</strong> The IPSS is a valid instrument to assess the impact of BPH symptoms on health and quality of life due to urinary symptoms.
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Chinese herbal medicine is commonly used as a treatment for benign prostatic hyperplasia （BPH）, but its efficacy and safety remain to be examined. To compare the efficacy and adverse events of Chinese herbal medicine alone or used adjuvantly with Western medications for BPH. Two independent reviewers searched the major electronic databases for randomized controlled trials comparing Chinese herbal medicine, either in single or adjuvant use with Western medication, with placebo or Western medication. Relevant journals and grey literature were also hand-searched. The outcome measures included changes in urological symptoms, urodynamic measures, prostate volume and adverse events. The frequency of commonly used herbs was also identified. Out of 13 922 identified citations of publications, 31 studies were included. Eleven studies with a Jadad score i〉 3 were selected for meta-analysis. Chinese herbal medicine was superior to Western medication in improving quality of life and reducing prostate volume. The frequency of adverse events in Chinese herbal medicine was similar to that of placebo and less than that of Western medication. The evidence is too weak to support the efficacy of Chinese herbal medicine for BPH due to the poor methodological quality and small number of trials included. The commonly used herbs identified here should provide insights for future clinical practice and research. Larger randomized controlled trials of better quality are needed to truly evaluate the efficacy of Chinese herbal medicine.
文摘Benign prostatic hyperplasia(BPH)is characterized by an enlarged prostate,lower urinary tract symptoms(LUTS),and a decreased urinary flow rate.Common in older men,BPH is a progressive disease that can eventually lead to complications including acute urinary retention(AUR)and the need for BPH-related surgery.Both normal and abnormal prostate growth is driven by the androgen dihydrotestosterone(DHT),which is formed from testosterone under the influence of 5-alpha reductase.Thus,5-alpha reductase inhibitors(5-ARIs)effectively reduce the serum and intraprostatic concentration of DHT,causing an involution of prostate tissue.Two 5-ARIs are currently available for the treatment of BPHdfinasteride and dutasteride.Both have been demonstrated to decrease prostate volume,improve LUTS and urinary flow rates,which ultimately reduces the risk of AUR and BPH-related surgery.Therefore,either alone or in combination with other BPH medications,5-ARIs are a mainstay of BPH management.
文摘Objective:Our objective was to characterize the safety and efficacy of the 180 W XPS-GreenLight laser in men with lower urinary tract symptoms secondary to a small volume benign prostatic hyperplasia(BPH).Methods:A retrospective analysis was performed for all patients who underwent 180 W XPSlaser photoselective vaporization of the prostate(PVP)vaporization of the prostate between 2012 and 2016 at two-tertiary medical centers.Data collection included baseline comorbidities,disease-specific quality of life scores,maximum urinary flow rate(Qmax),postvoid residual(PVR),complications,prostate volume and prostate-specific antigen(PSA).The secondary endpoints were the incidence of intraoperative and postoperative adverse events.Complications were stratified using the Clavien-Dindo grading system up to 90 days after surgery.Results:Mean age of men was 67.8 years old,with a mean body mass index of 29.7 kg/m2.Mean prostate volume as measured by transrectal ultrasound was 29 mL.Anticoagulation use was 47%and urinary retention with catheter at time of surgery was 17%.Mean hospital stay and catheter time were 0.5 days.Median follow-up time was 6 months with the longest duration of follow-up being 22.5 months(interquartile range,3-22.5 months).The International Prostate Symptom Score improved from 22.8±7.0 at baseline to 10.7±7.4(p<0.01)and 6.3±4.4(p<0.01)at 1 and 6 months,respectively.The Qmax improved from 7.70±4.46 mL/s at baseline to 17.25±9.30 mL/s(p<0.01)and 19.14±7.19 mL/s(p<0.001)at 1 and 6 months,respectively,while the PVR improved from 216.0±271.0 mL preoperatively to 32.8±45.3 mL(p<0.01)and 26.2±46.0 mL(p<0.01)at 1 and 6 months,respectively.The PSA dropped from 1.97±1.76 ng/mL preoperatively to 0.71±0.61 ng/mL(p<0.01)and 0.74±0.63 ng/mL at 1 and 6 months,respectively.No patient had a bladder neck contracture postoperatively and no capsular perforations were noted intraoperatively.Conclusion:The 180 W GreenLight XPS system is safe and effective for men with small volume BPH.PVP produced improvements in symptomatic and clinical parameters without any safety concern.It represents a safe surgical option in this under studied population.
文摘In this study we aimed to evaluate the impact of doxazosin treatment on erectile functions in patients with lower urinary tract symptoms （LUTS） and having erectile dysfunction （ED） at baseline. Fifty-three patients with LUTS （IPSS score 〉 7） whose maximum flow rate （Qmax） 〈 15 mL s-1 and PSA 〈 4 ng dL^-1 were enrolled in the study. Patients received doxazosin 4 nag once daily for 6 weeks. Subjective efficacy was assessed by IPSS, IPSS- Quality of Life （IPSS-QoL） for LUTS and efficacy was assessed by International Index of Erectile Function （IIEF） for erectile functions at baseline and sixth weeks. The objective efficacy was assessed by Q The patients were classified according to their self reported erectile status： group I had ED and group II did not have ED. At the endpoint, doxazosin significantly improved the total IPSS score （-7.7 ±6.1, P = 0.006）, IPSS-QoL score （-1.5 ± 1.5, P = 0.024） and Qmax （3.2 ± 4.6 mL s^-1, P = 0.002） over baseline. Mean decrease in IPSS and IPSS-QoL scores after the treatment period were 6.9 ＋ 6.4 （P 〈 0.001） and 0.95 4- 1.80 （P 〈 0.05） in group I, whereas 8.2 4- 5.8 （P 〈 0.001） and 1.9 4- 1.1 in group IX （P 〈 0.001）, respectively. Mean changes of Qmax values were 2.3 4- 3.3 mL s^-1 in group I （P 〈 0.05） and 3.7 4- 5.3 mL s-1 in group II （P 〈 0.001）. The improvement of IIEF-EF scores after the treatment period was only significant for group I. The efficacy of a-blocker therapy for LUTS was better by means of symptomatic relief for patients who did not have ED when compared with patients who had ED at baseline. However, slight improvement in erectile functions with a-blocker therapy was only seen in LUTS patients with ED.
文摘Background: Transurethral resection of prostate (TURP) is the gold standard in the surgical treatment of symptomatic benign prostatic hyperplasia (BPH). Blood loss is one of the most common complications of TURP. Objective: To evaluate the effect of preoperative dutasteride on bleeding related to TURP in patients with BPH. Materials and Methods: This prospective interventional study was done in the department of urology, Dhaka Medical College Hospital, Dhaka, Bangladesh during the period of July 2016 to June 2017. A total of 70 cases of BPH planned for TURP were included in this study according to the statistical calculation. Patients were randomly allocated to control group A (TURP without dutasteride) and dutasteride group B (TURP with dutasteride). Each group consisted of 35 patients. Group B patients were treated with dutasteride 0.5 mg/day for 4 weeks before TURP. The main outcome of blood loss was evaluated in terms of reduction in serum hemoglobin (Hb) and hematocrit (Hct) levels, which were measured before and 24 hours after surgery. Data were analyzed and compared by statistical tests. Results: Comparison of outcome between groups shows that there was a significant difference in term of pre-post operative change of hemoglobin and hematocrit levels in the control group A compared to the dutasteride group B (Hb = 2.96 ± 0.80 gm/dl vs. 1.81 ± 0.71 gm/dl, respectively, p = 0.001;Hct = 11.20% ± 2.12% vs. 6.07% ± 2.02%, respectively, p = 0.02). A significant lower mean blood loss was observed in the dutasteride group compared to the control group. Conclusion: Preoperative dutasteride therapy reduces blood loss related to TURP in patients with BPH. This therapy can be practiced to reduce surgical bleeding associated with TURP.
文摘BACKGROUND Transurethral columnar balloon dilatation of the prostate(TUCBDP) is a new surgical treatment, but its efficacy remains controversial because of limited clinical application.AIM To investigate the clinical effect of TUCBDP for benign prostatic hyperplasia(BPH).METHODS Overall, 140 patients with BPH who underwent surgical treatment were included in the study. A random number table was used to divide the participants into study and control groups(n = 70 per group). The study group underwent TUCBDP. The prostate resection surgical time, intraoperative blood loss, bladder irrigation time, catheter indwelling time, length of hospital stay, International Prostate Symptom Score(IPSS), maximum urine flow rate(Qmax), residual urine volume(RUV), changes in the International Erectile Function Score(ⅡEF-5) score, serum prostate-specific antigen(PSA), quality of life(QOL) score, and surgical complications were compared in both groups.RESULTS The operation time, intraoperative blood loss volume, bladder flushing time, urinary catheter indwelling time, and length of hospital stay were significantly lower in the study group than in the control group(P < 0.05). There were no significant differences in the IPSS, Qmax, and RUV measurements between the study and control groups(P > 0.05). However, at 3 mo post-surgery, the IPSS and RUV measurements were both lower(P < 0.05) and Qmax values were higher(P < 0.05) compared to the pre-surgery results in both groups. The ⅡEF-5 scores before and 3 mo after surgery were not significantly different between the study and control groups(P > 0.05). At 1 mo after surgery, the ⅡEF-5 score was higher in the study group than in the control group(P < 0.05). The serum PSA levels and QOL scores before treatment and at 1 and 3 mo after treatment were not significantly different between the study and control groups(P > 0.05). However, lower serum PSA levels and QOL scores were observed after 1 and 3 mo of treatment compared to pre-treatment levels in the study group(P < 0.05). The surgical complication rate of the study group(4.29%) was lower than that of the control group(12.86%;P < 0.05).CONCLUSION TUCBDP for BPH and transurethral resection of the prostate can achieve better results, but the former method is associated with less surgical trauma.
文摘Objective:Conventional treatments for benign prostatic hyperplasia(BPH)like 5alpha-reductase inhibitors and invasive surgery are associated with some obvious side effects.Conversely,evidence,though limited,has shown that alternative medicines are safer and have potential to improve the lower urinary tract symptoms(LUTS)and quality of life in addition to improving sexual dysfunction in patients with BPH.The current article aimed to include an overview of BPH,different ways of its management,and particularly its appreciation in Greco-Arab(Unani)system of medicine,one of the alternative medicinal systems.Methods:PubMed,Scopus,ScienceDirect,Web of Sciences,Google Scholar databases and classical texts of Greco-Arab medicine were searched for data collection.Results:In Unani system of medicine,BPH,traced under the headings of Waram unuq al-mathana(bladder neck swelling)and Insidad majra-i-mathana(bladder outlet obstruction),has been managed for centuries with herbal medicines yet demanding a comprehensive scientific validation.Among the herbs,Cucurbita pepo,Tribulus terrestris,Urtica dioica,and Linum usitatissimum are worth mentioning.Conclusion:For achieving the goal of LUTS-free ageing men,and safer and cost-effective future management of BPH,Unani herbal medicine could hopefully prove beneficial.
文摘Benign prostatic hyperplasia (BPH) is a chronic condition that is more common in older men. BPH most commonly causes symptoms associated with LUTS and bladder outlet obstruction. Lower urinary tract symptoms (LUTS) in men with BPH are a major cause of reduced quality of life in older men. If bladder outlet obstruction persists for a longer period of time, the contractility and voiding capacity of the detrusor muscle will gradually be affected by the obstructive factors, eventually leading to a loss of compensatory phase, characterised by a reduced electrical stimulation response, replacement of bladder muscle tissue by connective tissue, and a possible increase in voiding pressure, but a decrease in contractility of the detrusor muscle. As BOO progresses, it eventually leads to permanent contractile dysfunction of the detrusor muscle. Therefore, early initiation of surgical treatment in patients who are not well controlled by medication can reduce the complications associated with prostate enlargement. With the rise of minimally invasive treatment and the complications of open surgery, minimally invasive treatment of BPH has attracted increasing attention. Various emerging minimally invasive surgical modalities are being developed in clinical practice, and more and more minimally invasive techniques and concepts are focusing on safety, improving quality of life and reducing long-term complications to meet the different needs of different patients. Transurethral resection of the prostate (TURP) is currently the “gold standard” of minimally invasive surgical treatment, but with concerns about post-operative complications, the search for safer and more effective minimally invasive surgical options has become even more important. In recent years, with the increasing clinical application of new minimally invasive techniques such as various lasers, interventional treatments and implantable devices, there are more options for minimally invasive treatment of BPH. This article provides a brief review of research advances in the minimally invasive treatment of benign prostatic hyperplasia, with a view to informing clinical decisions.
文摘Background: Benign prostatic hyperplasia (BPH) is characterized by the abnormal proliferation of cells, leading to structural changes. It is one of the most common diseases in ageing men. Its clinical presentations are dominated by lower urinary tract symptoms (LUTS). The therapeutic methods can be grouped into two options: the medical option and the surgical option in which prostate enucleation is found. In recent years many studies have reported the onset of urinary incontinence (UI) after prostate enucleation. The management of UI occurring after prostate enucleation is embarrassing for both the practitioner and the patient, and generates additional costs. Purpose: Cite the causes of UI after prostate enucleation for BPH, as well as ways to prevent the onset of UI after this surgery, specifically by the study of the vesicosphincteric system aimed at improving the technique of enucleation;our review will also deal with the therapeutic means of UI. Method: We retrieved studies from Science Direct, Wiley and Pubmed. Results: There are multiple etiologies of UI after prostate enucleation including urethral sphincter insufficiency (USI) and bladder dysfunction (BD). The management of UI after surgery could be conservative, surgical, or use new technologies. Urodynamic assessment before prostate enucleation for BPH is relevant. Conclusion: UI is a common post-operative complication of prostate enucleation. The study of the vesicosphincteric system leads us to believe that prostate enucleation for BPH, partially sparing the mucosa and the external urethral sphincter could decrease the incidence of UI after surgery.
