ABSTRACT Objective To evaluate long‐term failure rates and complications after retropubic and transobturator midurethral sling procedures for primary stress urinary incontinence (SUI). Design Retrospective cohort study. Setting Academic medical centre. Population A previously described cohort of patients ( n = 1881) who underwent midurethral sling procedures (2002–2012) and a covariate‐matched cohort of patients with retropubic ( n = 570) or transobturator ( n = 317) slings. Methods Health record review with follow‐up extended by 9 years (through December 31, 2022). Main Outcome Measures Treatment failure (reoperation for recurrent SUI) and procedure‐associated complications. Results The duration of assessment was extended by 6.9 years for the retropubic group and by 6.4 years for the transobturator group. The median (IQR) follow‐up was 11.1 (5.1–14.5) years (retropubic, 11.4 [5.9–14.6]; transobturator, 9.6 [2.6–13.7]). Higher risk of reoperation was observed with transobturator (8.8%) than retropubic (4.4%) slings (unadjusted hazard ratio [HR], 2.29 [95% CI, 1.49–3.54]; p < 0.001; covariate‐matched analysis HR, 1.91 [95% CI, 1.15–3.17]; p = 0.01). The increased risk of reoperation with a transobturator sling was higher when the procedure was combined with prolapse repair (unadjusted HR, 6.34 [95% CI, 3.09–13.02]; p < 0.001; covariate‐matched analysis HR, 3.96 [95% CI, 1.35–11.58]; p = 0.01). Higher rates of reoperation for urinary retention were observed for the retropubic group than for the transobturator group (covariate‐matched analysis HR, 8.39 [95% CI, 1.11–63.22]; p = 0.04). Conclusion In this long‐term follow‐up study, midurethral slings had a low failure rate. Women with SUI undergoing transobturator sling placement plus prolapse repair had a greater risk of reoperation. However, women with retropubic slings had a greater risk of urinary retention requiring intervention.

Introduction and Hypothesis To report on clinical presentation, diagnosis, and outcomes after treatment of female urethral diverticulum (UD). Methods Using a record linkage system, women with a new diagnosis of UD at Mayo Clinic from January 1, 1980, through December 31, 2011, were identified. The presenting symptoms, clinical characteristics, diagnosis, and management of women presenting with UD were recorded. Outcomes after surgery were assessed using survival analysis. All statistical analyses were 2-sided and P values less than 0.05 were considered significant. Statistical analysis was done using SAS version 9.2 and JMP version 9.0 (SAS Institute Inc.). Results A total of 164 cases were identified. Median age at diagnosis was 46 years (range, 21–83). The most common presenting symptom was recurrent urinary tract infection (98, 59.8%), followed by urinary incontinence (81, 49.4%), dysuria (62, 37.8%), dyspareunia (37, 22.6%), and hematuria (15, 9.1%). Examination revealed vaginal mass in 55 (33.5%) of the women. A significant trend was noted toward an increase in use of both magnetic resonance imaging and computed tomography (P < 0.001) along with a progressive decrease in use of urethrogram (P < 0.001) for diagnosis of UD over the years. Among 114 women who underwent surgical treatment for UD, 14(12.3%) women presented with recurrent UD and the 5-year recurrence rate after surgery for UD was 23.4% (95% confidence interval, 13.9–37.0) and a reoperation rate of 17.0% (95% confidence interval, 8.8–30.2) at 5 years. Conclusions Female UD is a rare and unique condition. Clinical presentation is usually nonspecific, and magnetic resonance imaging is commonly used for confirming the diagnosis. Recurrence is not uncommon, and repeat surgical intervention might be needed.

Abstract We report a case of successful external cephalic version after preterm premature rupture of membranes. Transcervical amnioinfusion was used to facilitate the procedure due to minimal amniotic fluid, and the patient subsequently delivered vaginally. A femoral fracture was later identified in the neonate.

AbstractEndocrine regulation of uterine biology is critical for embryo receptivity and human reproduction. Uterine endometrium depends on extrinsic sex steroid input and hence likely has mechanisms that enable adaptation to hormonal variation. Emerging evidence suggests that sex steroid bioavailability in the endometrium is determined by adjusting their metabolic rate and fate via regulation of cytochrome (CYP) p450 enzymes. The CYP enzymes are targeted by ubiquitously expressed Sp/Krüppel-like (Sp/KLF) transcription factors. Specifically, KLF11 is highly expressed in reproductive tissues, regulates an array of endocrine/metabolic pathways via epigenetic histone-based mechanisms and, when aberrantly expressed, is associated with diabetes and reproductive tract diseases, such as leiomyoma and endometriosis. Using KLF11 as a model to investigate epigenetic regulation of endometrial first-pass metabolism, we evaluated the expression of a comprehensive array of metabolic enzymes in Ishikawa cells. KLF11 repressed most endometrial CYP enzymes. To characterize KLF11-recruited epigenetic regulatory mechanisms, we focused on the estrogen-metabolizing enzyme CYP3A4. KLF11 expression declined in secretory phase endometrial epithelium associated with increased CYP3A4 expression. Additionally, KLF11 bound to CYP3A4 promoter GC elements and thereby repressed promoter, message, protein as well as enzymatic function. This repression was epigenetically mediated, because KLF11 colocalized with and recruited the corepressor SIN3A/histone deacetylase resulting in selective deacetylation of the CYP3A4 promoter. Repression was reversed by a mutation in KLF11 that abrogated cofactor recruitment and binding. This repression was also pharmacologically reversible with an histone deacetylase inhibitor. Pharmacological alteration of endometrial metabolism could have long-term translational implications on human reproduction and uterine disease.
