Methodology: This was a prospective descriptive cross-sectional study carried out in the Radiology Department of Donka National Hospital over a period of ten (10) months. It involved 78 women who came to the department for hysterosalpingography and/or pelvic ultrasound examinations, as part of the exploration of infertility. Data collection involved the use of pre-established survey forms to gather information on the parameters studied. Sociodemographic parameters, ultrasound and hysterosalpingography results were studied. A correlation was made between age at marriage and infertility to determine whether early marriage has an impact on primary infertility, with a statically significant result for p value greater than 0.05. Results: The mean age of our patients was 33.7 ± 5.6 years, with extremes of 18 and 35 years. The 18-35 age group was the most represented, with a frequency of 80.7%. The 34% of our patients were married before the age of 18, with a marriage duration ranging from 6 months to 15 years. The indication for investigations was dominated by secondary infertility, with a frequency of 65%, followed by primary infertility (35%). All our women underwent ultrasound-hysterosalpingography, i.e. 100%, in search of the cause of infertility. Ultrasound was pathological in 35.8%. The most common ultrasound lesions were myomas and ovarian dystrophies, with 12.8% each. However, hysterosalpingography was pathological in 35%. Tubal obstructions affected almost a third of our women (29.5%), followed by phimosis and tubo-peritoneal adhesions. Conclusion: Diagnostic evaluation of infertility requires a multidisciplinary approach, including collaboration between infertility gynecologists, radiologists and other infertility specialists. Medical imaging remains indispensable in the evaluation of female infertility.展开更多

Ninety-eight(51%) patients were pregnant(<20 weeks). Time to completion of RDUS was 66 minutes longer than POCUS(95%CI 60–73, P<0.01). Patients randomized to the RDUS arm experienced a 120 minute longer ED length of stay(LOS)(95%CI 66–173, P<0.01)CONCLUSION: In patients who require pelvic ultrasound as part of their diagnostic evaluation, POCUS resulted in a signifi cant decrease in time to ultrasound and ED LOS.展开更多

METHODS: Eight consecutive patients with pelvic abscess that were not amenable to drainage under computed tomography(CT) guidance were referred for EUS-guided drainage. The underlying cause of the abscesses included diverticulitis in 4, postsurgical surgi-cal complications in 2, iatrogenic after enema in 1, and Crohn's disease in 1 patient. Abscesses were all drained under EUS guidance via a transrectal or transsigmoidal approach. RESULTS: EUS-guided placement of one or two 7 Fr pigtail stents was technically successful and uneventful in all 8 patients(100%). The abscess was perisigmoidal in 2 and was multilocular in 4 patients. All procedures were performed under conscious sedation and without fluoroscopic monitoring. Fluid samples were success-fully retrieved for microbiological studies in all cases and antibiotic policy was adjusted according to cultureresults in 5 patients. Follow-up CT showed complete re-covery and disappearance of abscess. The stents were retrieved by sigmoidoscopy in only two patients and had spontaneously migrated to outside in six patients. All drainage procedures resulted in a favourable clinical outcome. All patients became afebrile within 24 h after drainage and the mean duration of the postprocedure hospital stay was 8 d(range 4-14). Within a median follow up period of 38 mo(range 12-52) no recurrence was reported. CONCLUSION: We conclude that EUS-guided drain-age of pelvic abscesses without fluoroscopic monitoring is a minimally invasive, safe and effective approach that should be considered in selected patients.展开更多

However, its role in the prediction of ovarian torsion has been controversial. The aim of the study was to assess the validity of ultrasound in the prediction of ovarian torsion in patients with acute pelvic pain related to clinically suspected ovarian torsion. Methods: A retrospective observational study was conducted at the Ob/Gyn department using a 10-year chart review of all female patients older than 11 years of age with highly suspected ovarian torsion who underwent clinical assessment and ultrasound prior to surgery (n = 62). The sensitivity and specificity of ultrasound were determined by cross-tabulation of the ultrasound and surgical findings. Results: Of the suspected cases, 54 (87.1%) were confirmed to be cases of ovarian torsion by surgery. The majority of the cases were suggestive of ovarian torsion, which was indicated by clinical examination (77.4%), ultrasound (77.4%), or pathological examination (79%). Almost one-half of the cases (46.8%) showed a pain score >6;two-thirds (62.9%) presented with vomiting and/or nausea;and more than one-third (38.7%) presented with leukocytosis. The estimated sensitivity and specificity of ultrasound were 0.74 and 0.0, respectively. The positive predictive value was 0.83. Ultrasound was significantly associated with both clinical examination (p = 0.039) and pain score (p = 0.008). Conclusion: The diagnosis of ovarian torsion cannot be exclusively based on ultrasound. Both clinical and sonographical evaluation of acute pelvic pain should be considered for the diagnosis. A definitive diagnosis remains challenging.展开更多

Methods: In the first phase of this study we performed a sacrospinous anchor placement in four normal fresh-frozen female pelves. Afterwards, an endovaginal ultrasound was performed to visualize the anchor localization which was validated by dissection of the cadaveric pelves. In the second phase of the study: two groups of volunteer females with and without pelvic organ prolapsed (POP-group, vs NON-POP group) were evaluated by endovaginal ultrasound to localize the sacrospinous ligament. Results: Cadaveric dissection demonstrated accurate anchor placement into the 8/8 sacrospinous ligament. We performed endovaginal ultrasound in a total of 17 N-POP and 10 (POP) patients. Among the N-POP group, the right and left ischial spines were visible in 6/17 (35%) and (6/17) 35% vs 0/10 (0%) for both right and left sides in POP group (p = 0.008). The right sacrospinous ligament was visualized in 4/17 (23%) N-POP subjects and 0/10 POP subjects (p = 0.27) and the left sacrospinous ligament was visualized in 7/17 (41%) N-POP subjects and 2/10 POP subjects (p = 0.48). Conclusions: Sacrospinous ligament and the ischial spines couldn’t be reliably visualized among women with or without pelvic organ prolapse using endovaginal ultrasound, although the structures are visualized more in some of the non-prolapsed women. The sacrospinous anchoring device demonstrated accurate placement by cadaveric dissections.展开更多
