Risk Factors for De Novo Overactive Bladder After Midurethral Sling.

IMPORTANCE: The low incidence of de novo overactive bladder (OAB) symptoms after a midurethral sling (MUS) procedure better informs preoperative counseling. OBJECTIVE: The study aimed to measure the incidence and risk factors for de novo OAB after MUS. STUDY DESIGN: This was a retrospective cohort study of de novo OAB symptoms in patients who underwent MUS surgery in a health maintenance organization between January 1, 2008, and September 30, 2016. Patients were identified using Current Procedural Terminology codes for MUS and International Classification of Diseases, Tenth Revision codes for urinary urgency, frequency, nocturia, OAB, and urgency urinary incontinence (UUI). The cohort of patients was identified by the absence of these International Classification of Diseases, Tenth Revision codes 12 months preoperatively and the presence of these codes within 6 months after surgery. This cohort was used to calculate the rate of de novo OAB after MUS surgery. Clinical and demographic factors were abstracted. Statistical analysis was performed using descriptive, χ2 , simple logistic, and multiple logistic regression. RESULTS: During the study period, 13,893 patients underwent MUS surgery and 6,634 met the inclusion criteria. The mean age was 56.9 years, mean parity was 2.76, and mean body mass index was 28.9 (calculated as weight in kilograms divided by height in meters squared). Of these, 410 (6.1%) developed de novo OAB within 12 months. The most common symptoms were urgency (65.4%), UUI (42.2%), and frequency (19.8%). On multivariable regression modeling, de novo urgency and UUI were not associated with concurrent surgery ( P < 0.05). Increasing age and body mass index were associated with an increased risk of nocturia ( P < 0.05). CONCLUSIONS: The incidence of de novo OAB after MUS surgery was 6.1%. This aligns with current literature and critically informs preoperative counseling for MUS surgery.

Twelve Month Outcomes of Pelvic Organ Prolapse Surgery in Patients With Uterovaginal or Posthysterectomy Vaginal Prolapse Enrolled in the Multicenter Pelvic Floor Disorders Registry.

OBJECTIVE: The aim of the study was to compare 12-month subjective and objective outcomes between 3 approaches to apical pelvic organ prolapse (POP) surgery in patients presenting with uterovaginal or posthysterectomy vaginal prolapse enrolled in the Pelvic Floor Disorders Registry for Research. STUDY DESIGN: This was an analysis of a multicenter, prospective registry that collected both patient- and physician-reported data for up to 3 years after conservative (pessary) and surgical treatment for POP. Twelve-month subjective and anatomic outcomes for patients who underwent surgical treatment were extracted from the registry for analysis. Pelvic organ prolapse recurrence was defined as a composite outcome and compared between the 3 apical surgery groups (native tissue repair, sacrocolpopexy, colpocleisis) as well as the 2 reconstructive surgery groups (native tissue repair and sacrocolpopexy). RESULTS: A total of 1,153 women were enrolled in the registry and 777 (67%) opted for surgical treatment, of whom 641 underwent apical repair and were included in this analysis (404 native tissue repair, 187 sacrocolpopexy, and 50 colpocleisis). The overall incidence of recurrence was as follows: subjective 6.5%, anatomic 4.7%, retreatment 7.2%, and composite 13.6%. The incidence of recurrence was not different between the 3 surgical groups. When baseline patient characteristics were controlled for, composite POP recurrence between the native tissue and sacrocolpopexy groups remained statistically nonsignificant. Concurrent perineorrhaphy with any type of apical POP surgery was associated with a lower risk of recurrence (adjusted odds ratio, 0.43; 95% confidence interval, 0.25-0.74; P = 0.002) and prior hysterectomy was associated with a higher risk (adjusted odds ratio, 1.77, 95% confidence interval, 1.04-3.03; P = 0.036). CONCLUSION: Pelvic Floor Disorders Registry for Research participants undergoing native tissue apical POP repair, sacrocolpopexy, and colpocleisis surgery had similar rates of POP recurrence 12 months after surgery.

Performance of Perioperative Tasks for Women Undergoing Anti-incontinence Surgery: Developed by the AUGS Quality Improvement and Outcomes Research Network.

OBJECTIVES: Surgery for the correction of stress urinary incontinence is an elective procedure that can have a dramatic and positive impact on quality of life. Anti-incontinence procedures, like inguinal hernia repairs or cholecystectomies, can be classified as high-volume/low-morbidity procedures. The performance of a standard set of perioperative tasks has been suggested as one way to optimize quality of care in elective high-volume/low-morbidity procedures. Our primary objective was to evaluate the performance of 5 perioperative tasks-(1) offering nonsurgical treatment, (2) performance of a standard preoperative prolapse examination, (3) cough stress test, (4) postvoid residual test, and (5) intraoperative cystoscopy for women undergoing surgery for stress urinary incontinence-compared among surgeons with and without board certification in female pelvic medicine and reconstructive surgery (FPMRS). STUDY DESIGN: This study was a retrospective chart review of anti-incontinence surgical procedures performed between 2011 and 2013 at 9 health systems. Cases were reviewed for surgical volume, adverse outcomes, and the performance of 5 perioperative tasks and compared between surgeons with and without FPMRS certification. RESULTS: Non-FPMRS surgeons performed fewer anti-incontinence procedures than FPMRS-certified surgeons. Female pelvic medicine and reconstructive surgery surgeons were more likely to perform all 5 perioperative tasks compared with non-FPMRS surgeons. After propensity matching, FPMRS surgeons had fewer patients readmitted within 30 days of surgery compared with non-FPMRS surgeons. CONCLUSIONS: Female pelvic medicine and reconstructive surgery surgeons performed higher volumes of anti-incontinence procedures, were more likely to document the performance of the 5 perioperative tasks, and were less likely to have their patients readmitted within 30 days.

Retreatment of Stress Urinary Incontinence After Midurethral Sling With Prior Urethral Bulking.

IMPORTANCE: There is limited current literature regarding the retreatment of stress urinary incontinence (SUI) after midurethral sling (MUS) placement with prior urethral bulking. OBJECTIVE: The objective was to evaluate the retreatment and perioperative complications of MUS placement with prior urethral bulking compared with MUS placement without prior urethral bulking. STUDY DESIGN: This was a retrospective cohort study of patients within the Southern California Permanente Medical Group who underwent MUS placement from January 2009 to December 2020. Patients who underwent prior urethral bulking were compared with a control group without prior urethral bulking in a 1:1 ratio matched by age and MUS procedure date. The primary outcome was the retreatment of SUI after MUS placement with prior urethral bulking. Secondary outcomes were perioperative complications. Regression models were used to evaluate associations between retreatment and perioperative complications while controlling for confounding variables. RESULTS: Eighty-five patients who underwent MUS placement with prior urethral bulking were identified and matched with 85 control patients who underwent MUS placement without prior urethral bulking. Patients who underwent MUS placement without prior urethral bulking were more likely to have concomitant surgery. Linear regression analysis controlling for the effect of concomitant surgery revealed no difference in estimated blood loss and operative time between the 2 groups. In logistic regression analysis, there was no difference in the retreatment rate and perioperative complications between groups. CONCLUSION: We found that the unique treatment combination of MUS placement with prior urethral bulking for recurrent SUI seems to have a similar retreatment rate and perioperative complications as MUS placement without prior urethral bulking.

Rectocele: Correlation Between Defecography and Physical Examination.

IMPORTANCE: There is a lack of consensus regarding the clinical applicability of fluoroscopic defecography in evaluation of pelvic organ prolapse. OBJECTIVES: The aim was to evaluate the association between rectocele on defecography and posterior vaginal wall prolapse (PVWP) on physical examination. The secondary objective was to describe radiologic and clinical predictors of surgical intervention and outcomes. STUDY DESIGN: This was a retrospective review of patients enrolled in a large health maintenance organization who underwent defecography and were examined by a urogynecologist within 12 months. The electronic medical record was reviewed for demographic and clinical variables, including pelvic organ prolapse and defecatory symptoms, physical examination, and surgical intervention through 12 months after initial urogynecologic examination or 12 months after surgery if applicable. RESULTS: One hundred eighty-six patients met inclusion criteria. Of those, 168 (90.3%) had a rectocele on defecography and 31 (16.6%) had PVWP at or beyond the hymen. Rectocele size on defecography was poorly correlated with PVWP stage (spearman ρ = 0.18). Forty patients underwent surgical intervention. Symptoms of splinting, digitation, and stool trapping were associated with surgical intervention (odds ratio, 4.24; 95% confidence interval, 1.59-11.34; P < 0.01) as was advanced PVWP stage ( P < 0.01), while rectocele presence and size on defecography were not. Large rectocele size on defecography was correlated with persistent postoperative defecatory symptoms ( P = 0.02). CONCLUSIONS: We demonstrated a poor correlation between rectocele size on defecography and PVWP stage. Defecatory symptoms (splinting, digitation, stool trapping) and higher PVWP stage were associated with surgical intervention, while rectocele on defecography was not.

A Randomized Controlled Trial Evaluating the Effect of an Educational Video on Patient Understanding of Midurethral Sling.

OBJECTIVE: The primary objective was to evaluate the use of a novel video for enhancing patient knowledge of midurethral sling compared with standard handout. METHODS: Participants scheduled for midurethral sling were randomized to 1 of 2 preoperative educational interventions, either video or standard handout. The primary outcome was change in knowledge measured via a 15-question questionnaire completed immediately before and after the intervention. Secondary outcomes were knowledge retention, urinary symptoms, decision satisfaction, and regret measured via validated questionnaires at 2 and 6 weeks postoperatively. Data are presented as median (interquartile range) and comparisons between intervention groups made using non-parametric statistics. A sample size of 16 per arm was calculated to detect a 20% effect size. RESULTS: Thirty-eight participants, 19 per site, were randomized from August 2019 to October 2020 and 37 (97%) completed the primary outcome per protocol. Median age was 51 years (18 years), and there were no significant demographic differences between groups. Participants randomized to video demonstrated greater change in knowledge than those randomized to handout (+8.5 (3) vs +2.0 (4), P < 0.0001). Those randomized to video demonstrated improved 6 week postoperative urinary symptoms (Urogenital Distress Inventory-6, 0.0 [8.3] vs 14.6 [26.0]; P = 0.02; Incontinence Severity Index, 0.0 [2] vs 3.0 [4]; P = 0.005). There were no differences in satisfaction with decision (5.0 [0] video vs 5.0 [0.9] handout; P = 0.48) or decision regret (1.0 [0.5] video vs 1.0 [0.8] handout; P = 0.80) at 6 weeks postoperatively. CONCLUSIONS: A preoperative educational video improved knowledge and urinary symptoms after midurethral sling compared with a standard handout.

Bowel Obstruction After Sacrocolpopexy: A Case Series.

OBJECTIVES: Bowel obstruction after sacrocolpopexy (SC) can cause significant morbidity. The aim of this study was to delineate clinical and surgical factors associated with bowel obstruction after SC and to describe its presentation, management, and sequelae. METHODS: We performed a retrospective case series of patients who underwent open, laparoscopic, or robotic SC within a large health maintenance organization and a single academic medical center between January 1, 2009, and December 31, 2019. RESULTS: Of 3,231 patients who underwent SC, 32 (1.0%) experienced a bowel obstruction. Sacrocolpopexy was performed laparoscopically or robotically in 19 (59.4%) and abdominally in 13 (40.6%). The mean time to bowel obstruction was 1.9 years (SD, 2.5; range, 3 days to 8.8 years). In patients who experienced bowel obstruction, medical management was undertaken in 19 (61.3%) cases. Eight of the 13 (61.5%) surgically managed cases underwent bowel resection, and 3 cases (23.1%) reported partial mesh excision. Recurrent obstruction was seen in 2 (10.5%) of the medically managed and 2 (15.4%) of the surgically managed cases. CONCLUSIONS: Bowel obstruction is a rare complication of SC and our rate of at least 1.0% corroborates those in the literature. Obstruction occurs from days to years after SC. Nonsurgical management was effective in most cases, with low rates of recurrent obstruction. In surgically managed cases, the majority included bowel resection or mesh excision; however, mesh excision was not associated with a subsequent identifiable procedural intervention for recurrent prolapse. These data inform patient counseling and surgical planning before SC and aid in diagnosis and management of bowel obstruction after SC.

Prevalence and Nature of Sexist and Racial/Ethnic Microaggressions Against Surgeons and Anesthesiologists.

Importance: Workplace mistreatment can manifest as microaggressions that cause chronic, severe distress. As physician burnout becomes a global crisis, quantitative research to delineate the impact of microaggressions is imperative. Objectives: To examine the prevalence and nature of sexist and racial/ethnic microaggressions against female and racial/ethnic-minority surgeons and anesthesiologists and assess the association with physician burnout. Design, Setting, and Participants: This cross-sectional survey evaluated microaggressions and physician burnout within a diverse cohort of surgeons and anesthesiologists in a large health maintenance organization. A total of 1643 eligible participants were sent a recruitment email on January 8, 2020, 1609 received the email, and 652 replied, for a response rate of 41%. The study survey remained open until February 20, 2020. A total of 588 individuals (37%) were included in the study after exclusion criteria were applied. Exposures: The Maslach Burnout Inventory, the Racial Microaggression Scale, and the Sexist Microaggression Experience and Stress Scale. Main Outcomes and Measures: The primary outcomes were prevalence and nature of sexist and racial/ethnic microaggressions against female and racial/ethnic-minority surgeons and anesthesiologists using the Sexist Microaggression Experience and Stress Scale and Racial Microaggression Scale. Secondary outcomes were frequency and severity of microaggressions, prevalence of physician burnout, and associations between microaggressions and physician burnout. Results: Data obtained from 588 respondents (249 [44%] female, 367 [62%] racial/ethnic minority, 224 [38.1%] 40-49 years of age) were analyzed. A total of 245 of 259 female respondents (94%) experienced sexist microaggressions, most commonly overhearing or seeing degrading female terms or images. Racial/ethnic microaggressions were experienced by 299 of 367 racial/ethnic-minority physicians (81%), most commonly reporting few leaders or coworkers of the same race/ethnicity. Criminality was rare (18 of 367 [5%]) but unique to and significantly higher for Hispanic and Black physicians. Individuals who identified as underrepresented minorities were more likely to experience environmental inequities (odds ratio [OR], 4.21; 95% CI, 1.6-10.75; P = .002) and criminality (OR, 14.93; 95% CI, 4.5-48.5; P < .001). The prevalence of physician burnout was 47% (280 of 588 physicians) and higher among female physicians (OR, 1.60; 95% CI, 1.03-2.47; P = .04) and racial/ethnic-minority physicians (OR, 2.08; 95% CI, 1.31-3.30; P = .002). Female physicians who experienced sexist microaggressions (racial/ethnic-minority female physicians: OR, 1.84; 95% CI, 1.04-3.25; P = .04; White female physicians: OR, 1.99; 95% CI, 1.07-3.69; P = .03) were more likely to experience burnout. Racial/ethnic-minority female physicians (OR, 1.86; 95% CI, 1.03-3.35; P = .04) who experienced racial microaggressions were more likely to report burnout. Racial/ethnic-minority female physicians who had the compound experience of sexist and racial/ethnic microaggressions (OR, 2.05; 95% CI, 1.14-3.69; P = .02) were more likely to experience burnout. Conclusions and Relevance: The prevalence of sexist and racial/ethnic microaggressions against female and racial/ethnic-minority surgeons and anesthesiologists was high and associated with physician burnout. This study provides a valuable response to the increasing call for evidence-based data on surgical workplace mistreatment.

Vaginal Hysterectomy in a Large Health Maintenance Organization: Retrospective Application of a Clinical Algorithm.

STUDY OBJECTIVE: The primary objective was to describe practice patterns of benign hysterectomy within a large community health maintenance organization (HMO) and evaluate clinical and surgeon characteristics associated with the performance of vaginal hysterectomy (VH). Secondary objectives were to retrospectively apply a VH algorithm to determine how our practice patterns conform, and compare rates of perioperative complications among patients who did and did not meet the algorithm. Patient and surgeon characteristics, and perioperative complications, were compared between patients who underwent VH and did or did not meet the VH algorithm. DESIGN: Retrospective cohort study. SETTING: Large community HMO. PATIENTS: Women undergoing benign hysterectomy. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Route of hysterectomy, patient and surgeon characteristics, perioperative complications. One hundred and thirty-one of 984 (13.3%) benign hysterectomies from January 1, 2013 to June 30, 2015 were vaginal. Patients who were vaginally parous, Hispanic, had normal preoperative uterine size and documentation of uterine descent were more likely to have VH (all p <.05). High-volume surgeons performed 18.8% of their hysterectomies vaginally, as compared to low-volume surgeons who performed 11.4% of their hysterectomies vaginally (p <.01). VH were more likely to be performed by surgeons with longer practice durations than non-vaginal hysterectomies (16.3 vs 12.2 years, p <.01). Seventy-five percent of patients who met the VH algorithm underwent non-vaginal hysterectomy and they had longer operative durations and higher rates of postoperative complications compared to patients who underwent VH. Conversely, patients who underwent VH despite not meeting the VH algorithm did not have significantly different rates of perioperative complications or blood loss than patients who met the VH algorithm. CONCLUSION: Seventy-five percent of patients deemed appropriate for VH by our algorithm underwent non-vaginal hysterectomy and had more postoperative complications and longer operative durations. Our data suggest that surgeon characteristics, including surgical volume and duration of practice, may explain some of this performance gap. These findings contribute additional insight into current practice patterns and describe clinical factors that should be included in VH algorithms.

Ergonomics in Surgery: A Review.

OBJECTIVE: Work-related musculoskeletal disorders (WMSDs) are prevalent among surgeons and may result in practice modification. We aimed to perform a comprehensive review of the English-language literature regarding ergonomic risk, prevalence of WMSDs, and unique ergonomic considerations by route of surgery. METHODS: Multiple searches were performed of PubMed and University library resources to access English-language publications related to surgeon ergonomics. Combinations of keywords were used for each mode of surgery, including the following: "ergonomics," "guidelines," "injury," "operating room," "safety," "surgeon," and "work-related musculoskeletal disorders." Each citation was read in detail, and references were reviewed. RESULTS: Surgeon WMSDs are prevalent, with rates ranging from 66% to 94% for open surgery, 73% to 100% for conventional laparoscopy, 54% to 87% for vaginal surgery, and 23% to 80% for robotic-assisted surgery. Risk factors for injury in open surgery include use of loupes, headlamps, and microscopes. Unique risks in laparoscopic surgery include table and monitor position, long-shafted instruments, and poor instrument handle design. In vaginal surgery, improper table height and twisted trunk position create injury risk. Although robotic surgery offers some advantages, it remains associated with trunk, wrist, and finger strain. Surgeon WMSDs often result in disability but are under-reported to institutions. Additionally, existing research tools face limitations in the operating room environment. CONCLUSIONS: Work-related musculoskeletal disorders are prevalent among surgeons but have received little attention owing to under-reporting of injury and logistical constraints of studying surgical ergonomics. Future research must aim to develop objective surgical ergonomics instruments and guidelines and to correlate ergonomics assessments with pain and tissue-level damage in surgeons with WMSDs. Ergonomics training should be developed to protect surgeons from preventable, potentially career-altering injuries.

Impact of surgical training on the performance of proposed quality measures for hysterectomy for pelvic organ prolapse.

BACKGROUND: Recent healthcare reform has led to increased emphasis on standardized provision of quality care. Use of government- and organization-approved quality measures is 1 way to document quality care. Quality measures, to improve care and aid in reimbursement, are being proposed and vetted in many areas of medicine. OBJECTIVES: We aimed to assess performance of proposed quality measures that pertain to hysterectomy for pelvic organ prolapse stratified by surgical training. The 4 quality measures that we assessed were (1) the documentation of offering conservative treatment of pelvic organ prolapse, (2) the quantitative assessment of pelvic organ prolapse (Pelvic Organ Prolapse-Quantification or Baden-Walker), (3) the performance of an apical support procedure, and (4) the performance of cystoscopy at time of hysterectomy. STUDY DESIGN: Patients who underwent hysterectomy for pelvic organ prolapse from January 1 to December 31, 2008, within a large healthcare maintenance organization were identified by diagnostic and procedural codes within the electronic medical record. Medical records were reviewed extensively for demographic and clinical data that included the performance of the 4 proposed quality measures and the training background of the primary surgeon (gynecologic generalist, fellowship-trained surgeon in Female Pelvic Medicine and Reconstructive Surgery, and "grandfathered" Female Pelvic Medicine and Reconstructive Surgery). Data were analyzed with the use of descriptive statistics. Inferential statistics with chi-squared tests were used to compare performance rates of quality measures that were stratified by surgical training. Probability values <.05 were considered statistically significant. RESULTS: Six hundred thirty patients who underwent hysterectomy for pelvic organ prolapse in 2008 had complete records available for analysis. Fellowship-trained surgeons performed 302 hysterectomies for pelvic organ prolapse; grandfathered Female Pelvic Medicine and Reconstructive Surgery surgeons performed 98 hysterectomies, and gynecologic generalist surgeons performed 230 hysterectomies. Fellowship-trained surgeons had the highest performance rates for individual quality measures (91.4-98.7%) and cumulative performance of all measures (80.8% of cases). Grandfathered Female Pelvic Medicine and Reconstructive Surgery surgeons performed significantly fewer measures (80.6-95.9% performance rate for individual measures; 65.3% cumulatively for all measures) than fellowship-trained surgeons and more than gynecologic generalists (64.3-70% for individual measures; 29.1% cumulatively for all measures). There was an association between surgeon training background and number of hysterectomies performed for pelvic organ prolapse, with specialist surgeons performing more hysterectomies. When quality measure performance was stratified by surgeon volume, similar significant associations were found, with high-volume surgeons performing more quality measures than low-volume surgeons. CONCLUSION: Within a large healthcare maintenance organization, fellowship-trained Female Pelvic Medicine and Reconstructive Surgery surgeons were more likely to perform proposed quality measures in women who underwent hysterectomy for pelvic organ prolapse compared with those surgeons without such training. Grandfathered Female Pelvic Medicine and Reconstructive Surgery surgeons performed measures more frequently than gynecologic generalists but less than fellowship-trained surgeons. Further study is indicated to correlate the proposed quality measures with clinical outcomes.

Evaluation of microscopic hematuria and risk of urologic cancer in female patients.

BACKGROUND: Urologic cancer has a lower prevalence in women compared with men; however, there are no differences in the recommended evaluation for women and men with microscopic hematuria. OBJECTIVES: The purpose of this study was to identify risk factors that are associated with urologic cancer in women with microscopic hematuria and to determine the applicability of a hematuria risk score for women. STUDY DESIGN: We conducted a retrospective cohort study within an integrated healthcare system in Southern California. All urinalyses with microscopic hematuria (>3 red blood cells per high-power field) that were performed from 2009-2015 were identified. Women who were referred for urologic evaluation were entered into a prospective database. Clinical and demographic variables that included the presence of gross hematuria in the preceding 6 months were recorded. The cause of the hematuria, benign or malignant, was entered into the database. Cancer rates were compared with the use of chi-square and logistic regression models. Adjusted risk ratios of urologic cancer were estimated with the use of multivariate regression analysis. We also explored the applicability of a previously developed, gender nonspecific, hematuria risk score in this female cohort. RESULTS: A total of 2,705,696 urinalyses were performed in women during the study period, of which 552,119 revealed microscopic hematuria. Of these, 14,539 women were referred for urologic evaluation; clinical data for 3573 women were entered into the database. The overall rate of urologic cancer was 1.3% (47/3573). In women <60 years old, the rate of urologic cancer was 0.6% (13/2053) compared with 2.2% (34/1520) in women ≥60 years old (P<.01). In women who reported a history of gross hematuria, the rate of urologic cancer was 5.8% (20/346) compared with a 0.8% (27/3227) in women with no history of gross hematuria (P<.01). In multivariate analysis, > 60 years old (odds ratio, 3.1; 95% confidence interval, 1.6-5.9), a history of smoking (odds ratio, 3.2; 95% confidence interval, 1.8-5.9), and a history of gross hematuria in the previous 6 months (odds ratio, 6.2; 95% confidence interval, 3.4-11.5) were associated with urologic cancers. A higher microscopic hematuria risk score was associated with an increased risk of cancer in this test cohort (P<.01). Women in the highest risk group had a urologic cancer rate of 10.8% compared with a rate of 0.5% in the lowest risk group. CONCLUSIONS: In this female population, >60 years old and a history of smoking and/or gross hematuria were the strongest predictors of urologic cancer. Absent these risk factors, the rate of urologic cancer did not exceed 0.6%. A higher hematuria risk score correlated significantly with the risk of urologic cancer in this female test cohort.

Recurrent Urinary Tract Infection After Midurethral Sling: A Retrospective Study.

OBJECTIVES: Our primary objective was to estimate the proportion of patients with culture-proven urinary tract infection (UTI) and recurrent UTI after midurethral sling (MUS), as well as to evaluate their risk factors. Our secondary objective was to characterize the difference in the proportion of patients with recurrent UTI before and after MUS. METHODS: We conducted a retrospective study of patients who underwent MUS from 2009 to 2012 within a large health maintenance organization and subsequently had documentation of at least 1 positive urine culture (>100 K CFU/mL) within 1 year. Validated procedural and diagnostic codes were used to identify patients undergoing MUS and the diagnosis of UTI, respectively. RESULTS: Of the 7461 MUS performed, 883 (12%) patients had at least 1 culture-proven UTI and 258 (3.5%) patients met the definition of recurrent UTI postoperatively. Of those 883 patients, 89 (10%) patients met the definition of recurrent UTI before, and 258 (29%) patients after, MUS. McNemar χ test revealed that patients were more likely to have recurrent UTI after MUS compared with before (P < 0.0001). In multivariate logistic regression, Caucasian (odds ratio [OR], 1.60, 95% confidence interval [95% CI], 1.12-2.29; P = 0.01) and African-American (OR, 3.42; 95% CI, 1.42-8.29; P = 0.01) ethnicity, older age (OR, 1.02; 95% CI, 1.00-1.04; P = 0.03), and a history of recurrent UTI (OR 3.79, 95% CI 1.88-7.93, P = 0.0003) were risk factors for postoperative recurrent UTI. CONCLUSIONS: In this population, preoperative recurrent UTI was the only modifiable risk factor associated with an increased risk of postoperative recurrent UTI.

Preoperative vaginal estrogen and midurethral sling exposure: a retrospective cohort study.

INTRODUCTION AND HYPOTHESIS: We evaluated whether the use of estrogen vaginally prior to synthetic midurethral sling insertion mediates the risk of mesh exposure. A secondary aim was to evaluate other factors that may be associated with mesh exposure. METHODS: We performed a retrospective cohort study of patients undergoing midurethral sling insertion from January to December 2010 within the Southern California Permanente Medical Group. Women who used estrogen vaginally prior to surgery were classified as those who filled a prescription between 1 and 45 days before surgery or whose medical records indicated its use at the time of preoperative evaluation. Logistic regression analysis was used to calculate odds ratios (OR) and 95 % confidence intervals (CI) for factors associated with mesh exposure while controlling for confounding variables. RESULTS: A total of 1544 patients met inclusion criteria, of whom 248 (16.1 %) used estrogen vaginally prior to surgery. Mean age was 53.7 years (range 27-89). Thirty-seven (2.4 %) women were diagnosed with mesh exposure, of whom 19 underwent surgical reoperation. In multivariate logistic regression analysis, preoperative use of estrogen vaginally was not associated with the risk of mesh exposure (OR 0.79, CI 0.26-2.38, p = 0.67). Age, body mass index, menopausal status, use of hormone replacement therapy, smoking status, and diabetes were not associated with risk of mesh exposure. CONCLUSIONS: Preoperative use of estrogen vaginally did not appear to mediate the risk of mesh exposure following midurethral sling placement in this cohort.

Laparoscopic Hysterectomy and Urinary Tract Injury: Experience in a Health Maintenance Organization.

STUDY OBJECTIVES: To evaluate the incidence, detection, characteristics, and management of urinary tract injury in a cohort undergoing laparoscopic hysterectomy, and to identify potential risk factors for urinary tract injury with laparoscopic hysterectomy. DESIGN: Retrospective analysis (Canadian Task Force classification II-2). SETTING: Kaiser Permanente San Diego Medical Center, 2001 to 2012. PATIENTS: Women who underwent attempted laparoscopic hysterectomy for benign indications. INTERVENTIONS: Total laparoscopic hysterectomy, laparoscopic-assisted vaginal hysterectomy, and laparoscopic supracervical hysterectomy. MEASUREMENTS AND MAIN RESULTS: Demographic and clinical characteristics, surgical techniques, and perioperative complications were abstracted from the medical record. Multivariable logistic regression analysis assessed independent risk factors for ureteral or bladder injury. RESULTS: A total of 3523 patients (mean age, 45.9 ± 8.0 years; median parity, 2; range, 0-10), with a median body mass index (BMI) of 29 kg/m(2) (range, 16-72 kg/m(2)), underwent laparoscopic hysterectomy; 20% had intraoperative cystoscopy. The incidence of urinary tract injury was 1.3% (46 of 3523); of the 46 patients with injuries, 19 (0.54%) had ureteral injuries, 25 (0.71%) had bladder injuries, and 2 (0.06%) had both types. Of the 21 ureteral injuries, 6 (29%) were diagnosed intraoperatively and 15 (71%) were diagnosed postoperatively, including 4 with normal intraoperative cystoscopy. Of the 27 bladder injuries, 23 (85%) were identified intraoperatively. In multivariable logistic analysis, a BMI of 26 to 30 kg/m(2) (compared with >30 kg/m(2)) was associated with an increased risk of ureteral injury, and a BMI ≤25 kg/m(2) (compared with >30 kg/m(2)) and the presence of endometriosis were associated with an increased risk of bladder injury. CONCLUSION: Urinary tract injury occurred in 1.3% of laparoscopic hysterectomies, with ureteral injuries almost as common as bladder injuries. Normal intraoperative cystoscopy findings did not exclude the presence of ureteral injury.

Repeat midurethral sling compared with urethral bulking for recurrent stress urinary incontinence.

OBJECTIVE: To compare the effectiveness and safety of repeat midurethral sling with urethral bulking after failed midurethral sling. METHODS: This is a retrospective cohort study of patients within Kaiser Permanente Southern California Medical Group who underwent a midurethral sling for stress urinary incontinence (SUI) from 2008 to 2011 and subsequently had either a midurethral sling or urethral bulking for recurrent SUI. Current Procedural Terminology codes were used to identify patients and electronic medical records were queried for individual patient information. Our primary outcome was either subjective failure defined by SUI or objective failure defined as a positive cough stress test, urodynamic stress incontinence, or retreatment for SUI. Secondary outcomes included perioperative complications and adverse events. RESULTS: Of 6,914 midurethral slings performed, 165 patients underwent a repeat procedure for recurrent SUI, including 98 midurethral slings and 67 urethral bulking. Of the 165 patients who underwent repeat procedures, there were 11 failures (11.2%) in the midurethral sling group and 26 failures (38.8%) in the urethral bulking group (P=.004). There were no differences in perioperative complications or adverse events between the groups. In multivariable logistic regression, risk of failure was significantly higher in those undergoing urethral bulking compared with those undergoing midurethral sling (odds ratio 3.49, 95% confidence interval 1.34-9.09, P=.01). CONCLUSIONS: In a managed care population, urethral bulking was associated with higher risk of failure than repeat midurethral sling after primary midurethral sling failure with no differences in perioperative complications or adverse events. LEVEL OF EVIDENCE: II.

Effects of concomitant surgeries during midurethral slings (MUS) on postoperative complications, voiding dysfunction, continence outcomes, and urodynamic variables.

OBJECTIVE: To determine whether concomitant surgeries affected outcomes in a randomized trial comparing retropubic midurethral sling (MUS) vs transobturator MUS. METHODS: Subjects (n = 597) were stratified into 4 groups based on type of concomitant surgeries: group I had anterior/apical with or without posterior repairs (n = 79, 13%); group II had posterior repairs or perineorrhaphy only (n = 38, 6%); group III had nonprolapse procedures (n = 34, 6%); and group IV had no concomitant surgeries (n = 446, 75%). Complication rates, voiding dysfunction, objective and subjective surgical failure rates, and changes in urodynamic values (postop minus preop) were assessed and compared in these 4 groups. RESULTS: There were no differences in complications, voiding dysfunction, and subjective failure outcomes between these 4 groups. Group I had lower odds ratio of objective surgical failure compared with group IV (OR 0.38, 95% CI 0.18-0.81, P = .05). The OR of failure of all patients undergoing concomitant surgeries (groups I-III) was lower than group IV (OR 0.57, 95% CI 0.35-0.95, P = .03). The change in Pdet@Qmax (from pressure-flow) was significantly higher in group III vs IV (P = .01). The change in Q(max.) (from uroflowmetry) was significantly less in groups I and II vs group IV (P = .046 and .04, respectively). CONCLUSION: Concomitant surgeries did not increase complications. Subjects who underwent certain concomitant surgeries had lower failure rates than those undergoing slings only. These data support safety and efficacy of performing concomitant surgery at the time of MUS.

Impact of surgically induced weight loss on pelvic floor disorders.

INTRODUCTION AND HYPOTHESIS: Given the increased prevalence of obesity and pelvic floor disorders (PFDs), we estimated changes in prevalence, bother, and quality of life (QOL) for PFDs in obese women undergoing bariatric surgery. We hypothesized PFDs would improve after surgical weight loss. METHODS: The prevalence, bother, and QOL impact of PFDs were estimated using validated measures. McNemar's and paired t tests were used to compare pre- and postprocedural outcomes. Power calculations deemed that 90 individuals would achieve at least 80 % power to detect a decrease in prevalence of 12 %. RESULTS: The baseline mean (± standard deviation) age and body mass index (BMI) of the 98 women were 43.3 ± 11.8 years and 39.7 ± 6.2 kg/m.(2) BMI decreased to 34.4 ± 5.8 at 6 months and 34.0 ± 5.6 at 12 months. Whereas the overall prevalence of stress urinary incontinence (SUI) decreased from 22/69 (32 %) at baseline to 10/69 (15 %) at 6 months (p = 0.006) and 14/69 (20 %) at 12 months (p = 0.027), there were no significant decreases in overall prevalence of other PFDs. However, for women with SUI, overactive bladder (OAB), and anal incontinence at baseline, 11/23 (48 %), 8/11 (73 %) and 4/20 (20 %) resolved at 12 months, respectively. Pelvic Floor Impact Questionnaire scores decreased from baseline to 12 months (p < 0.001). Mean visual analog scores for women with SUI, OAB, and anal incontinence decreased at 12 months. CONCLUSIONS: Surgical weight loss resulted in resolution of symptoms in nearly half of women with SUI and three quarters of women with OAB and was associated with significant improvement in QOL.

Long-term outcomes after native tissue vs. biological graft-augmented repair in the posterior compartment.

INTRODUCTION AND HYPOTHESIS: We aimed to compare the outcomes of native tissue vs. biological graft-augmented repair in the posterior compartment. We hypothesized that the addition of graft would result in superior anatomic and functional outcomes. METHODS: A retrospective review of posterior repairs between 2001 and 2008 was performed to compare the anatomic and functional outcomes between native tissue and graft-augmented techniques. Mann-Whitney and chi-square tests were used. Power calculation determined that 32 subjects were needed in each group. RESULTS: One hundred twenty-four native tissue and 69 graft-augmented repairs were performed with a median follow-up of 35.8 months (range, 6 to 157 months). Anatomic success was similar for native tissue vs. graft (Bp < -1, 86% vs. 80% and Bp ≤ 0, 97% vs. 97%; all p > 0.05). Postoperative splinting and incomplete evacuation was greater in the graft group (splinting, 85% vs. 68%; p = 0.04 and incomplete evacuation, 85% vs. 64%; p = 0.03). CONCLUSION: Long-term success of posterior repair is high. Graft augmentation does not appear to improve anatomic or functional outcomes.
