Introduction and Hypothesis: The objective was to develop a prediction model for urinary tract infection (UTI) after pelvic surgery., Methods: We utilized data from three tertiary care centers of women undergoing pelvic surgery. The primary outcome was a UTI within 8 weeks of surgery. Additional variables collected included procedural data, severity of prolapse, use of mesh, anti-incontinence surgery, EBL, diabetes, steroid use, estrogen use, postoperative catheter use, PVR, history of recurrent UTI, operative time, comorbidities, and postoperative morbidity including venous thromboembolism, surgical site infection. Two datasets were used for internal validation, whereas a third dataset was used for external validation. Algorithms that tested included the following: multivariable logistic regression, decision trees (DTs), naive Bayes (NB), random forest (RF), gradient boosting (GB), and multilayer perceptron (MP)., Results: For the training dataset, containing both University of British Columbia and Mayo Clinic Rochester data, there were 1,657 patients, with 172 (10.4%) UTIs; whereas for the University of Calgary external validation data, there were a total of 392 patients with a UTI rate of 16.1% (n = 63). All models performed well; however, the GB, DT, and RF models all had an area under the curve (AUC) > 0.97. With external validation the model retained high discriminatory ability, DT: AUC = 0.88, RF: AUC = 0.88, and GB: AUC = 0.90., Conclusions: A model with high discriminatory ability can predict UTI within 8 weeks of pelvic surgery. Future studies should focus on prospective validation and application of randomized trial models to test the utility of this model in the prevention of postoperative UTI., (© 2024.

Introduction and Hypothesis: Support of the vaginal apex is paramount for a durable repair of pelvic organ prolapse (POP). Our aim is to assess national utilization of apical suspension procedures for the surgical treatment of complete POP. We hypothesize that there might be a high rate of apical suspension with advanced prolapse., Methods: The 2006-2016 National Surgical Quality Improvement Program database was queried for a primary postoperative diagnosis of complete POP. The primary outcome was type of repair. Secondary outcomes included patient characteristics associated with apical suspension or colpocleisis. Procedures were delineated using CPT codes. Chi-squared and multivariate logistic regression analyses were used to evaluate factors associated with repair type., Results: A total of 2,784 women underwent surgery for complete POP with a mean age of 64.6 ± 11.0 years. Overall, 1,300 (46.7%) patients underwent apical suspension: 487 sacrocolpopexies (17.5%), 428 extraperitoneal suspensions (15.4%), and 391 uterosacral suspensions (14.0%). 5.2% (144) underwent colpocleisis, and 47.5% (1,332) of women had a concurrent hysterectomy (CH). With CH, 38.6% (502) had apical suspension or colpocleisis versus 69.5% (940) of post-hysterectomy cases. On logistic regression, CH was inversely associated with apical suspension (adjusted odds ratio [aOR] 0.37, CI 0.32-0.44, p < 0.001). Colpocleisis was associated with older age (aOR 4.9 per 10 years, CI 3.8-6.3, p < 0.001), post-hysterectomy surgery (aOR 0.23, CI 0.1-0.4, p < 0.001 for CH), and higher comorbidity index (OR 1.7, CI 1.1-2.6, p = 0.009). Complication rates are similar with and without apical suspension (8.2% versus 7.0%, p = 0.269)., Conclusions: During surgery for complete POP, an apical suspension procedure is performed in 46.7% of patients and is more common post-hysterectomy.

Introduction and Hypothesis: The purpose of this study was to evaluate the accuracy of the American College of Surgeons National Surgery Quality Improvement Program (ACS NSQIP) surgical risk calculator in predicting postoperative complications in patients undergoing pelvic organ prolapse surgery., Methods: We performed a retrospective review of 354 patients who underwent surgery for pelvic organ prolapse from 2013 to 2017 at a single academic institution. Patient medical information and surgical procedure were entered into the calculator to obtain predicted complication rates, which were compared with observed complications. Logistic regression, C-statistic, and Brier score were used to assess the accuracy of the calculator., Results: Of 354 patients included in the analysis, 79.7% were under the age of 75, and 41.5% were classified as American Society of Anesthesiologists class ≥3. The majority of patients underwent robotic sacrocolpopexy (40.7%) or uterosacral ligament suspension (36.4%), followed by colpocleisis, abdominal sacrocolpopexy, and extraperitoneal suspension. Complications were experienced by 100 patients (28.3%). Most common complications were urinary tract infection (n = 57), surgical site infection (n = 42), and readmission (n = 16); other complications were rare. The surgical risk calculator displayed poor predictive ability for experiencing a complication (C-statistic = 0.547, Brier score = 0.25)., Conclusions: The NSQIP surgical risk calculator displayed poor predictive ability in our cohort of patients undergoing surgery for pelvic organ prolapse, suggesting that this tool might have limited clinical applicability to individual patients in this population.

Introduction and Hypothesis: Preoperative counseling about salpingectomy with pelvic surgery is recommended by the American College of Obstetrics and Gynecology for ovarian cancer risk reduction. Our objective was to determine recent practice patterns and patient factors associated with salpingectomy with vaginal hysterectomy (VH) for pelvic organ prolapse (POP) in the USA. We hypothesize that salpingectomy might have become more common in recent years., Methods: We queried the 2014-2016 National Surgical Quality Improvement Program database for women with a postoperative diagnosis of POP who underwent VH with any combination of pelvic reconstructive procedures. CPT codes do not differentiate salpingectomy from salpingo-oophorectomy, so subjects were stratified by whether concurrent adnexectomy was performed. Chi-squared and multivariate logistic regression analyses were used to evaluate characteristics associated with adnexectomy. Propensity score matching was utilized when evaluating postoperative complication rates., Results: Of 5,344 women who underwent VH, 2019 (37.8%) had adnexectomy. Adnexectomy rate increased from 34.4% in 2014 to 46.8% in 2016 (p < 0.001). Adnexectomy rates of fellowship-trained urogynecologists and general gynecologists were similar (36.0% vs 38.8%, p = 0.197). On logistic regression analysis, patients more likely to undergo adnexectomy were < 65 years old (OR 0.844, CI 0.75-0.95, p = 0.004), had BMI <30 (OR 0.76, CI 0.68-0.86, p < 0.001), and were non-smokers (OR 0.78, CI 0.64-0.95, p = 0.016). Mean operative time was 17 min longer with adnexectomy (145 vs 128 min, p < 0.001). There were no differences in postoperative complications or reoperation rates between groups., Conclusions: Adnexectomy during VH for POP is safe and increasingly utilized by gynecology surgeons in the USA.

Objective: To determine if the presence of cerebral white matter disease (WMD) affects the response to anti-cholinergic medications., Materials and Methods: This was a retrospective cohort of age-matched patients treated for OAB with anti-cholinergic medications between January 2010 and December 2017. Inclusion criteria were a chief complaint of OAB, never evaluated by a urogynecologist for OAB, treated with a maximum dose for a minimum of 4 weeks, and underwent head computed tomography (CT) within 12 months of starting therapy. Patients with WMD were matched 1:1 by age and number of prior failed antimuscarinics to controls with normal head CTs. Exclusion criteria included incomplete documentation of therapeutic response, non-WMD CT abnormalities, and non-idiopathic OAB. The primary outcome was anti-cholinergic treatment failure. Pairwise analysis between groups was performed using Wilcoxon rank-sum and Fisher's exact test where appropriate. Univariate logistic regression was performed, and any variable that was associated with treatment failure and a p value ≤ 0.2 was included in the multivariable regression analysis., Results: Sixty-eight cases were matched with 68 controls. Patients with WMD were more likely to have undergone hysterectomy (57.4% vs. 41.2%, p = 0.04) and to use diuretics (31.1% vs. 19.1%, p = 0.04). Patients with WMD were more likely to fail treatment compared with controls (60.7% vs. 29.4%, p = 0.004). After adjusting for confounders, WMD was strongly associated with an increased probability of failure (aOR = 7.31, 95% CI: 1.49-12.20). Additional significant risk factors for treatment failure were the previous number of failed medications (aOR = 3.65 per medication, 95% CI: 1.48-9.01) and a rising HbA1c (aOR: 1.39 per 1.0% increase, 95% CI: 1.0-1.91)., Conclusion: WMD is independently associated with anti-muscarinic treatment failure in women with overactive bladder symptoms.

Introduction and Hypothesis: Opportunistic salpingectomy (OS) at the time of benign hysterectomy has recently emerged as a potential primary preventive modality for ovarian cancer. Our objective was to determine whether the reported rate of OS at the time of prolapse surgery is similar to the rate of OS at the time of gynecologic surgery for non-prolapse indications., Methods: An anonymous online survey was sent to the Society of Gynecologic Surgery members. Responses were divided into surgeons who did and did not perform OS at the time of prolapse repair. Differences between surgeons who did and did not perform OS were evaluated using the chi-square test. Multivariable logistic regression was used to identify which responses related to increased odds of performing OS., Results: There were 117 (33.1%) completed responses; of these, 98 (83.8%) reported performing OS at the time of prolapse repair, which was similar to the reported rate of OS at the time of hysterectomy for non-prolapse indications, 82.1%. After multivariable logistic regression, performance of salpingectomy at the time of hysterectomy for a non-prolapse indication (aOR: 17.9, 95% CI: 3.11-42.01), use of a laparoscopic or robotic surgical approach (aOR 14.1, 95% CI: 1.81-32.21) and completion of an FPMRS fellowship (aOR: 3.47, 95% CI: 1.20-10.02) were associated with a higher likelihood of performing OS at the time of prolapse repair., Conclusions: OS at the time prolapse repair is performed more frequently with concomitant hysterectomy compared with OS at the time of post-hysterectomy prolapse repair and is similar to rates of OS performed at the time of hysterectomy for non-prolapse indications.

Introduction and Hypothesis: There is limited data available regarding the risk for perioperative cardiac morbidity following pelvic reconstructive surgery (PRS). We sought to determine the incidence of cardiac arrest and myocardial infarction within 30 days of pelvic organ prolapse (POP) surgery and determine which factors may contribute to an increased risk of these complications., Methods: Using the American College of Surgeons National Quality Improvement Program (NSQIP) database, we identified patients who underwent PRS procedures between 2010 to 2015 using Current Procedural Terminology (CPT) codes. Patient demographics and clinical and surgical factors were obtained. Patients who experienced myocardial infarction or cardiac arrest (MICA) were compared with patients without these complications. Differences between groups were calculated using the chi-square and Student's t test. Stepwise backward multivariate logistic regression was used to identify factors associated with acute cardiac morbidity., Results: A total of 46, 367 women were identified. The incidence of MICA was 0.11% and of death was 0.01% for the entire cohorot. Age >70 years [adjusted odds ratio (aOR) = 2.99, 95% confidence interval (CI) 1.56-5.73], length of stay >1 day (aOR = 3.34, 95% CI 1.70-6.40), dependent functional status (aOR = 5.99 95% CI 1.95-16.32), hypertension (aOR = 2.86, 95% CI 1.36-6.04), American Society of Anesthesiologists (ASA) class 3 (aOR = 2.01, 95% CI 1.10-3.64), and inpatient status (aOR = 4.35, 95% CI 1.78-10.49)., Conclusion: The rate of MICA is low following PRS. Additional studies are necessary to determine whether more extensive preoperative cardiac evaluation is warranted in this patient population.

Introduction and Hypothesis: Disorders of micturition result from a wide variety of conditions and evaluation often involves multiple diagnostic modalities. However, the sensitivity and specificity of these techniques are highly variable and may not always yield a diagnosis. Novel imaging techniques such as ultrasound shear wave elastography may help to improve diagnostic accuracy., Methods: Continent women were recruited from outpatient gynecology offices from a tertiary medical system. Participants underwent ultrasound evaluation with measurement of the shear wave velocity (SWV) of the bladder neck (BN). SWV was used to determine the Young's modulus of the bladder neck. The median bladder neck stiffness was calculated and univariate and step-wise and backward multivariate logistic regression analyses were used to identify significant patient characteristics associated with bladder neck stiffness above or below the median., Results: Fifty-seven women underwent SWE of the bladder; 12 were excluded, and 45 were included in the analysis. The median bladder neck stiffness of the study population was 22 (17.1-28.2) kPa. Age greater than 45 years was associated with a bladder neck stiffness above the median, OR 8.39, p < 0.001. Having no vaginal deliveries was also associated with a bladder neck stiffness greater than 22 kPa, unadjusted OR 4.76 (95 % CI 1.41-20.0, p = 0.012). Bladder volume and bladder neck thickness were not significantly associated with bladder neck stiffness above or below the median., Conclusion: Trans-abdominal shear wave elastography can be used to quantitatively assess bladder neck stiffness. This technique may potentially be useful for evaluating chronic urinary retention.
