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.

Importance Rectovaginal fistulas (RVFs) are challenging to treat, often requiring multiple surgical interventions. Research into novel therapies is limited by the lack of a sizeable and representative animal model. Given the similarities in porcine and human vaginal and rectal tissue, pigs are an ideal species for translation to human patients. Objective The objective of this study was to develop a feasible and reproducible RVF model in pigs. Study Design Six female pigs underwent RVF creation and were divided into 3 groups according to the following methods: (1) placement of 1-inch disc magnets across the rectovaginal septum, (2) a 1-inch round defect created using electrocautery and placement of a 1-inch stainless-steel gauge stent, (3) a 1-inch round defect using electrocautery without subsequent stenting. Fistulas were evaluated at 6 weeks with measurements and photographic documentation. The animals were euthanized between 12 and 14 weeks. The primary outcome of this study was fistula patency. Secondary outcomes were fistula dimension and histologic appearance of the fistula tract. Results All pigs did well with no infection or complications related to fistula creation. Both surgical methods reliably resulted in a patent fistula at 14 weeks: cautery alone and cautery with gauge stenting. Only 1 patent fistula in the magnet group was noted at the time of euthanasia. All patent fistulas showed histologic evidence of complete epithelialization of the fistula tract. Conclusions This study demonstrates 3 safe and feasible methods for RVF creation in pigs, with 2 methods showing increased reliability.

Importance As gender-affirming care expands, hysterectomies for gender dysphoria are increasing, but data comparing outcomes to benign hysterectomies remain limited. Objectives The objectives of this study were to compare perioperative characteristics and 30-day outcomes between transgender and gender diverse individuals (TGDI) undergoing gender-affirming hysterectomy (GAH) and patients undergoing hysterectomy for benign indications, by surgical approach. Study Design This was a retrospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program data (October 2015–December 2022). TGDI undergoing GAH were identified by gender dysphoria diagnosis and hysterectomy Current Procedural Terminology codes. Approaches included abdominal hysterectomy (AH), laparoscopic/robotic hysterectomy (L/RH), laparoscopically assisted vaginal hysterectomy (LAVH), and vaginal hysterectomy (VH). A matched cohort was created based on demographics and comorbidities. Primary outcomes were operative time, length of stay (LOS), and 30-day complications. Results A total of 975 TGDI undergoing GAH were included; 82% of GAHs were minimally invasive, mostly L/RH. GAH represented 0.7% of all benign hysterectomies, increasing over time ( P <0.001). TGDI (970) were matched to controls. In L/RH, TGDI had longer operative times (113 vs 97 min, P <0.001) but shorter LOS (0 vs 1 d, P <0.001). Similar patterns were seen in VH: longer operative times (103 vs 62 min, P <0.001) and shorter LOS (0 vs 1 d, P =0.018). In AH, TGDI had shorter LOS (1 vs 2 d, P =0.006) with similar operative times. No significant differences were found in LAVH or complications across groups. Conclusion GAH is safe with perioperative outcomes comparable to benign hysterectomy. TGDI experience shorter hospital stays and low complication rates. Promoting minimally invasive and vaginal approaches can enhance equitable, high-quality care for TGDI.

This joint Clinical Consensus Statement on the safety and feasibility of concomitant urogynecologic and gynecologic oncology surgical procedures reflects statements drafted by content experts from the American Urogynecologic Society and the Society of Gynecologic Oncology. The writing group used a Delphi process to evaluate statements developed from a structured literature search and assessed consensus. A total of 35 statements were assessed in the following categories: (1) background, (2) treatment options, (3) timing of concurrent surgery, (4) risk factors, and (5) value-based care. Of the 35 statements, 28 reached consensus on initial review. Three statements were omitted, and 4 statements were revised and reached consensus following second review utilizing the Delphi process.

Importance Exposure to the surgical management of obstetric anal sphincter injuries (OASIS) is limited during obstetrics training. Objectives The objective of this study was to quantify residents' exposure to OASI repair during 4-year obstetrics and gynecology (OBGYN) residency and examine temporal trends over a 16-year period. Study Design This was a retrospective cohort study of residents' exposure to OASIS at a community academic hospital from 2007 to 2022. Individuals with documented OASIS (third- or fourth-degree laceration) by International Classification of Diseases, Ninth and Tenth Revisions, codes during vaginal delivery (VD), spontaneous vaginal delivery (SVD), or operative vaginal delivery (OVD), were included. Delivery rates and OBGYN resident positions were examined. Temporal trends in OASIS were analyzed in 4-year epoch to determine average resident exposure during OBGYN residency. Results During the 16-year study period, there were 103,234 deliveries (62% VD, 4% OVD, 34% cesarean delivery). Among VDs, there were 2,344 (3.4%) OASIS with 88.5% classified as third-degree and 11.5% as fourth degree. The OASI rate decreased from 4.2% (2007–2010) to 2.9% (2019–2022), whereas OBGYN residents increased by 49% (67 to 99; P < 0.001). Average resident exposure to OASIS decreased from 11 (2007–2010) to 5 (2019–2022; P = 0.55). Subclassification revealed that residents were exposed to 5 third-degree repairs and less than 1 fourth-degree repair, on average, during 2019–2022. Conclusions During 4 years of training, average resident exposure was to 7 OASIS, 6 third degree, and 1 fourth degree. Limited exposure to OASIS during residency may be detrimental, as surgical treatment is a complicated yet essential obstetric procedure that carries significant risk of patient morbidity and potential long-term sequelae. Therefore, reliance on supplementation with simulation may improve surgeon competence in OASI management.

Abstract This is a single Institute, prospective cohort study. We collected twenty- two postmenopausal women with pelvic organ prolapse planning to undergo vaginal hysterectomy with transvaginal pelvic reconstructive surgery, with or without a concomitant anti-incontinence procedure. Vaginal swabs and urine samples were longitudinally collected at five time points: preoperative consult visit (T1), day of surgery prior to surgical scrub (T2), immediately postoperative (T3), day of hospital discharge (T4), and at the postoperative exam visit (T5). Women experiencing urinary tract infection symptoms provided a sample set prior to antibiotic administration (T6). Microbiome analysis on vaginal and urinary specimens at each time point. Region V3-V5 of the 16S ribosomal RNA gene was amplified and sequenced. Sample DNA was analyzed with visit T1, T2, T5 and T6. Six (27.3%) participants developed postoperative urinary tract infection whose vaginal sample at first clinical visit (T1) revealed beta-diversity analysis with significant differences in microbiome structure and composition. Women diagnosed with a postoperative urinary tract infection had a vaginal microbiome characterized by low abundance of Lactobacillus and high prevalence of Prevotella and Gardnerella species. In our cohort, preoperative vaginal swabs can predict who will develop a urinary tract infection following transvaginal surgery for pelvic organ prolapse.

Importance Racial and ethnic disparities exist in urogynecologic surgery; however, literature identifying specific disparities after sling operations for stress incontinence are limited. Objective The objective of this study was to evaluate racial and ethnic disparities in surgical complications within 30 days of midurethral sling operations. Study Design This retrospective cohort study identified women who underwent an isolated midurethral sling operation between 2014 and 2021 using the American College of Surgeons National Surgical Quality Improvement Program database. Women were stratified by racial and ethnic category to assess the primary outcome, 30-day surgical complications, and the secondary outcome, comparison of urinary tract infections (UTIs). Results There were 20,066 patients included. Mean age and body mass index were 53.9 years and 30.8, respectively. More Black or African American women had diabetes and hypertension, and more American Indian or Alaska Native women used tobacco. The only difference in 30-day complications was stroke/cerebrovascular accident, which occurred in only 1 Asian, Native Hawaiian or other Pacific Islander patient (0.1%, P < 0.0001). The most frequent complication was UTI (3.3%). Black or African American women were significantly less likely to have a diagnosis of UTI than non-Hispanic White (P = 0.04), Hispanic White (P = 0.03), and American Indian or Alaska Native women (P = 0.04). Conclusions Surgical complications within 30 days of sling operations are rare. No clinically significant racial and ethnic differences in serious complications were observed. Urinary tract infection diagnoses were lower among Black or African American women than in non-Hispanic White, Hispanic White, and American Indian or Alaska Native women despite a greater comorbidity burden. No known biologic reason exists to explain lower UTI rates in this population; therefore, this finding may represent a disparity in diagnosis and treatment.

Importance Obesity adds complexity to the decision of surgical approach for pelvic organ prolapse; data regarding perioperative complications are needed. Objective The aim of the study was to evaluate associations of body mass index (BMI) and surgical approach (vaginal vs laparoscopic) on perioperative complications. Study Design Patients who underwent prolapse surgery were identified via the Current Procedural Terminology codes from the American College of Surgeons National Surgical Quality Improvement Program database 2007–2018. Thirty-day major complications were compared across BMI to identify an inflection point, to create a dichotomous BMI variable. Multivariable logistic regression was used to assess the association between BMI and complications. An interaction term was introduced to evaluate for effect modification by operative approach. Results A total of 26,940 patients were identified (25,933 BMI < 40, 1,007 BMI ≥ 40). The proportion of patients experiencing a major complication was higher in the BMI ≥ 40 group (2.0 vs 1.1%, P = 0.007). In multivariate analysis, the odds of a major complication was 1.8 times higher for women with a BMI ≥ 40 (95% confidence interval, 1.1–2.9, P = 0.04). There was a significant interaction between operative approach and BMI; therefore, further analyses were restricted to either vaginal or laparoscopic operative approaches. Among women who underwent vaginal prolapse repair, there was no difference in the odds of a major complication (adjusted odds ratio, 1.4; 0.8–2.4; P = 0.06). Among women who underwent laparoscopic repair, those with a BMI ≥ 40 were 6 times more likely to have a major complication (adjusted odds ratio, 6.0; 2.5–14.6; P < 0.001). Conclusions Body mass index ≥ 40 was associated with an increased odds of a 30-day major complication. This association was greatest in women who underwent a laparoscopic prolapse repair.

Importance Improving opioid stewardship is important, given the common use of opioids and resultant adverse events. Evidence-based prescribing recommendations for surgeons may help reduce opioid prescribing after specific procedures. Objective The aim of this study was to assess longitudinal prescribing patterns for patients undergoing pelvic organ prolapse surgery in the 2 years before and after implementing evidence-based opioid prescribing recommendations. Study Design In December 2017, a 3-tiered opioid prescribing recommendation was created based on prospective data on postoperative opioid use after pelvic organ prolapse surgery. For this follow-up study, prescribing patterns, including quantity of opioids prescribed (in oral morphine equivalents [OMEs]) and refill rates, were retrospectively compared for patients undergoing prolapse surgery before (November 2015–November 2017; n = 238) and after (December 2017–December 2019; n = 361) recommendation implementation. Univariate analysis was performed using the Wilcoxon rank sum and χ 2 tests. Cochran-Armitage trend tests and interrupted time-series analysis tested for significance in the change in OMEs prescribed before versus after recommendation implementation. Results After recommendation implementation, the quantity of postoperative opioids prescribed decreased from median 225 mg OME (interquartile range, 225, 300 mg OME) to 71.3 mg OME (interquartile range, 0, 112.5 mg OME; P < 0.0001). Decreases also occurred within each subgroup of prolapse surgery: native tissue vaginal repair (P < 0.0001), robotic sacrocolpopexy (P < 0.0001), open sacrocolpopexy (P < 0.0001), and colpocleisis (P < 0.003). The proportion of patients discharged following prolapse surgery without opioids increased (4.2% vs 36.6%; P < 0.0001), and the rate of opioid refills increased (2.1% vs 6.0%; P = 0.02). Conclusions With 2 years of postimplementation follow-up, the use of procedure-specific, tiered opioid prescribing recommendations at our institution was associated with a significant, sustained reduction in opioids prescribed. This study further supports using evidence-based recommendations for opioid prescribing.
