Estimated Levator Ani Subtended Volume: A Predictive Biomarker for Surgical Outcomes Following Native Tissue Apical Repair.

OBJECTIVE: The aim of the study was to investigate the clinical utility of estimated levator ani subtended volume (eLASV) as a prospective preoperative biomarker for prediction of surgical outcomes. STUDY DESIGN: This is a prospective case-control pilot study. Patients were recruited and gave consent between January 2018 and December 2020. Surgical failure was defined by composite score. The eLASV was calculated for each patient based on a previously published algorithm. Descriptive statistics, Fisher exact test, log-binomial regression, area under a receiver operating characteristics, Bland-Altman plot, Lin coefficient, and κ coefficient were all performed for analysis. RESULTS: Fifty-one patients gave consent, 31 completed preoperative magnetic resonance imaging, 27 underwent surgery (uterosacral ligament suspension), and 19 followed up for 1-year examination. Five patients (26.3%) were defined as surgical failure with median eLASV volume of 57.0 (interquartile range, 50.1-66.2). Fourteen patients (73.7%) were defined as surgical success with median eLASV of 28.2 (interquartile range, 17.2-24.3). Eighty percent of the surgical failure group (4/5) had elevated volume of eLASV, where only 14.3% of the success group (2/14) had an elevated volume (P = 0.0173). No confounders were found and unadjusted log-binomial regression suggested that patients with a high eLASV were 8.7 (95% confidence interval, 1.2-61.9) times more likely to experience surgical failure compared with those with low eLASV. The c-statistic (area under a receiver operating characteristics) was high at 0.829 along with Lin concordance coefficient of 0.949 (95% confidence interval, 0.891-0.977) for continuous data between the 2 interrater observer teams. CONCLUSIONS: In this small prospective pilot study, patients with elevated eLASV on a preoperative pelvic magnetic resonance imaging were associated with an increased risk for surgical failure at 1 year regardless of age, body mass index, stage, or parity.CLINICAL TRIAL REGISTRATION:ClinicalTrials.gov, NCT03534830.

A Retrospective Cohort Study to Identify the Risk Factors for Urinary Tract Infection After Office Procedures.

OBJECTIVE: The objective of this study is to identify the incidence of and risk factors for urinary tract infection (UTI) after office cystoscopy and urodynamic studies (UDS) in a female population. METHODS: This was a retrospective cohort study investigating incidence of and risk factors for UTI after office testing. Inclusion criteria included women presenting for either cystoscopy or UDS from September 2019 to February 2020. Modified Poisson regression with robust error variance was used to identify risk factors for UTI after cystoscopy and UDS in a female population. RESULTS: A total of 274 patients met inclusion criteria. One hundred eighty-five patients underwent office cystoscopy. Nine (4.8%) had a postcystoscopy UTI. Significant risk factors for postcystoscopy UTI included recurrent UTI (relative risk, 7.51; 95% confidence interval, 1.66-34.05) and a history of interstitial cystitis (relative risk, 4.56; 95% confidence interval, 1.52-13.73). Of those with recurrent UTI, 13.7% had a postcystoscopy UTI. Among patients with interstitial cystitis, 25% had a postcystoscopy UTI. One hundred ninety-two patients underwent UDS. Ten (5.2%) developed a post-UDS UTI. No risk factors were identified. CONCLUSIONS: Patients with recurrent UTI were 7.51 times more likely to develop a UTI after cystoscopy, whereas those with interstitial cystitis were 4.56 times more likely to develop a UTI after cystoscopy. The incidence of UTI after UDS was low overall. Understanding who is at higher risk of postprocedural UTIs may help identify subpopulations that may benefit from prophylactic strategies.

Vesicovaginal fistula repair at the time of colpocleisis.

INTRODUCTION AND HYPOTHESIS: The objectives of this video are to discuss the presentation, evaluation, and surgical management of a patient with a vesicovaginal fistula at the time of colpocleisis. METHOD: We present the case of an 83-year-old woman with a history of stage IV prolapse who had had a pessary device removed. Urine had been noted to be in the vaginal vault, leading to suspicion of a vesicovaginal fistula. Following evaluation, the patient decided to proceed with surgical management. The patient underwent a vesicovaginal fistula repair with concomitant colpocleisis. A cystoscopy was performed at the conclusion of the case where the bilateral ureteral stents were removed and a strong efflux was noted at both ureteral orifices. RESULTS: At the patient's 1-month follow-up, she had no complaints of prolapse or vaginal leaking. CONCLUSION: Neglect of a vaginal pessary can lead to serious complications, indicating the importance of patient education and careful follow-up. Surgical planning is a key component in effectively managing a vesicovaginal fistula with ureteral presentation in order to preserve ureteral integrity. Concomitant vesicovaginal repair and colpocleisis can be performed safely with effective cure of a vesicovaginal fistula and stage IV prolapse.

Adnexal surgery at the time of hysterectomy in women 65 years and older undergoing hysterectomy for prolapse: do practice trends differ by route of surgery?

INTRODUCTION AND HYPOTHESIS: The objective was to determine whether the rate of adnexal surgery varies by route of hysterectomy in women over the age of 65 undergoing hysterectomy for prolapse. We hypothesized that women undergoing vaginal hysterectomy would be less likely to undergo bilateral salpingo-oophorectomy (BSO) at the time of their hysterectomy for prolapse. METHODS: This was a cross-sectional analysis using the National Inpatient Sample (NIS) database. Our primary outcome was concomitant adnexal surgery performed at the time of hysterectomy, classified into five groups: BSO, unilateral salpingo-oophorectomy (USO), bilateral salpingectomy (BS), other adnexal surgery, and no adnexal surgery. The study sample included women aged 65 years and older who underwent hysterectomy between 1 January 2009 and 31 December 2014 and with a diagnosis of genital prolapse. RESULTS: Of the 91,292 patients over the age of 65 who underwent a hysterectomy for prolapse, the majority of hysterectomies were vaginal (69%), followed by abdominal (13%), laparoscopic (11%), and robotic (7%). The number of women having a hysterectomy and undergoing a BSO was much lower for vaginal than for other hysterectomy types; 20.3% of women undergoing vaginal hysterectomies had a BSO, compared with 79.2% in abdominal, 81.8% in laparoscopic, and 73.8% in robotic-assisted procedures. Women who received vaginal hysterectomies were five times as likely (RR: 5.02, 95% CI: 4.70-5.35) to have no concomitant adnexal procedure compared with other routes of hysterectomy. CONCLUSIONS: Women over the age of 65 undergoing hysterectomy for prolapse are significantly less likely to have adnexal surgery if undergoing hysterectomy via vaginal route compared with the other routes.

A multicenter retrospective cohort study comparing urethral diverticulectomy with and without pubovaginal sling.

BACKGROUND: Urethral diverticulum is a rare entity and requires a high suspicion for diagnosis based on symptoms and physical exam with confirmation by imaging. A common presenting symptom is stress urinary incontinence (SUI). The recommended treatment is surgical excision with urethral diverticulectomy. Postoperatively, approximately 37% of patients may have persistent and 16% may have de novo SUI. An autologous fascial pubovaginal sling (PVS) placed at the time of urethral diverticulectomy (UD) has the potential to prevent and treat postoperative SUI. However, little has been published about the safety and efficacy of a concomitant pubovaginal sling. OBJECTIVE: The objective of this study was to compare the clinical presentation, outcomes, complications, and diverticulum recurrence rates in women who underwent a urethral diverticulectomy with vs without a concurrent pubovaginal sling. STUDY DESIGN: This multicenter, retrospective cohort study included women who underwent a urethral diverticulectomy between January 1, 2000, and December 31, 2016. Study participants were identified by Current Procedure Terminology codes, and their records were reviewed for demographics, medical or surgical history, symptoms, preoperative testing, concomitant surgeries, and postoperative outcomes. Symptoms, recurrence rates, and complications were compared between women with and without a concomitant pubovaginal sling. The primary outcome was the presence of postoperative stress urinary incontinence symptoms. Based on a stress urinary incontinence rate of 50% with no pubovaginal sling and 10% with a pubovaginal sling, we needed a sample size of 141 participants who underwent diverticulectomy without a pubovaginal sling and 8 participants with a pubovaginal sling to achieve 83% power with P<.05. RESULTS: We identified 485 diverticulectomy cases from 11 institutions who met the inclusion criteria; of these, 96 (19.7%) cases had a concomitant pubovaginal sling. Women with a pubovaginal sling were older than those without a pubovaginal sling (53 years vs 46 years; P<.001), and a greater number of women with pubovaginal sling had undergone diverticulectomy previously (31% vs 8%; P<.001). Postoperative follow-up period (14.6±26.9 months) was similar between the groups. The pubovaginal sling group had greater preoperative stress urinary incontinence (71% vs 33%; P<.0001), dysuria (47% vs 30%; P=.002), and recurrent urinary tract infection (49% vs 33%; P=.004). The addition of a pubovaginal sling at the time of diverticulectomy significantly improved the odds of stress urinary incontinence resolution after adjusting for prior diverticulectomy, prior incontinence surgery, age, race, and parity (adjusted odds ratio, 2.27; 95% confidence interval, 1.02-5.03; P=.043). It was not significantly protective against de novo stress urinary incontinence (adjusted odds ratio, 0.86; 95% confidence interval, 0.25-2.92; P=.807). Concomitant pubovaginal sling increased the odds of postoperative short-term (<6 weeks) urinary retention (adjusted odds ratio, 2.5; 95% confidence interval, 1.04-6.22; P=.039) and long-term urinary retention (>6 weeks) (adjusted odds ratio, 6.98; 95% confidence interval, 2.20-22.11; P=.001), as well as recurrent urinary tract infections (adjusted odds ratio, 3.27; 95% confidence interval, 1.26-7.76; P=.013). There was no significant risk to develop a de novo overactive bladder (adjusted odds ratio, 1.48; 95% confidence interval, 0.56-3.91; P=.423) or urgency urinary incontinence (adjusted odds ratio, 1.47; 95% confidence interval, 0.71-3.06; P=.30). A concomitant pubovaginal sling was not protective against a recurrent diverticulum (adjusted odds ratio, 1.38; 95% confidence interval, 0.67-2.82; P=.374). Overall, the diverticulum recurrence rate was 10.1% and did not differ between the groups. CONCLUSION: This large retrospective cohort study demonstrated a greater resolution of stress urinary incontinence with the addition of a pubovaginal sling at the time of a urethral diverticulectomy. There was a considerable risk of postoperative urinary retention and recurrent urinary tract infections in the pubovaginal sling group.

Cost-effectiveness of a preoperative pelvic MRI in pelvic organ prolapse surgery.

OBJECTIVE: To investigate the cost-effectiveness of preoperative pelvic magnetic resonance imaging (MRI) in identifying women at high risk of surgical failure following apical repair for pelvic organ prolapse (POP). METHODS: A decision tree (TreeAgePro Healthcare software) was designed to compare outcomes and costs of screening with a pelvic MRI versus no screening. For the strategy with MRI, expected surgical outcomes were based on a calculated value of the estimated levator ani subtended volume (eLASV) from previously published work. For the alternative strategy of no MRI, estimates for surgical outcomes were obtained from the published literature. Costs for surgical procedures were estimated using the 2008-2014 National Inpatient Sample (NIS). A cost-effectiveness analysis from a third-party payer perspective was performed with the primary measure of effectiveness defined as avoidance of surgical failure. Deterministic and probabilistic sensitivity analyses were performed to assess how robust the calculated incremental cost-effectiveness ratio was to uncertainty in decision tree estimates and across a range of willingness-to-pay values. RESULTS: A preoperative MRI resulted in a 17% increased chance of successful initial surgery (87% vs. 70%) and a decreased risk of repeat surgery with an ICER of $2298 per avoided cost of surgical failure. When applied to annual expected women undergoing POP surgery, routine screening with preoperative pelvic MRI costs $90 million more, but could avoid 39,150 surgical failures. CONCLUSION: The use of routine preoperative pelvic MRI appears to be cost-effective when employed to identify women at high risk of surgical failure following apical repair for pelvic organ prolapse.

A 10-Year Case Series of Surgically Managed Periurethral Masses at a Single Tertiary Care Institution.

OBJECTIVE: This study aimed to present the evaluation, diagnoses, and surgical management of symptomatic periurethral masses of women at an academic institution. METHODS: This study is an institutional review board-approved retrospective case series of women who presented with a symptomatic periurethral mass and scheduled for surgery within the Department of Urology and Female Pelvic Medicine and Reconstructive Surgery over a 10-year period (October 2003-July 2014). RESULTS: Fifty-nine women (mean age, 46 years; range, 22-73 years) were evaluated during the study period. Final pathology revealed 38 (64%) urethral diverticula and 21 (36%) from other benign etiologies. Of the 38 urethral diverticula, 2 (5%) were associated with adenocarcinoma and 4 (11%) with previous bulking agents. Of the 21 nondiverticula, there were 7 (12%) Skene duct cysts/abscesses, 3 (5%) Gartner duct cysts, 2 (3%) vaginal wall inclusion cysts, 2 (3%) bulking agents, 2 (3%) urethral polyps, and one (2%) of each of the following: leiomyoma, angiomyofibroblastoma, redundant vaginal mucosa epithelium, suture abscess, and encapsulated mesh remnant. Fifty-seven women underwent surgical excision (97%), and 2 elected observation. Most (78%) reported resolution of symptoms after excision. Of the patients surgically managed, 7% had postoperative stress urinary incontinence and 12% had persistent lower urinary tract symptoms. Of the 38 women with urethral diverticula, 17% had recurrence and were more likely to have multiple diverticula (44% vs 8%, P = 0.03). CONCLUSION: Although urethral diverticulum was the most common cause of a periurethral mass, final pathology revealed a variety of benign diagnoses in more than one-third of cases, demonstrating the importance of a thorough investigation for accurate diagnosis.

Furosemide Use and Time to Confirmation of Ureteral Patency During Intraoperative Cystoscopy: A Randomized Controlled Trial.

OBJECTIVE: To investigate the effect of intravenous administration of furosemide on the time to confirmation for ureteral patency during intraoperative cystoscopy. METHODS: In a double-blind randomized controlled trial, intravenous administration of furosemide 10 mg was compared with placebo (normal saline) to investigate the effect of furosemide on the time to confirmation for ureteral patency during intraoperative cystoscopy. The primary outcome was time to confirmation of ureteral patency. Secondary outcomes included adverse reaction to study medication and delayed diagnosis of ureteric injury. A sample size of 72 per group (N=144) was powered to detect a 3-minute difference in time to confirmation of ureteral patency between groups. RESULTS: From May 2017 to March 2018, 215 patients were eligible for inclusion and 150 were randomized, with 145 available for final evaluation. The two groups were similar in regard to baseline characteristics. The administration of intravenous furosemide 10 mg in a routine cystoscopy resulted in a shorter time to confirmation compared with the administration of the placebo (86.5 seconds, interquartile range 55.0-137.0 vs 165.0 seconds, interquartile range 77.0-280.0; P<.05). Furthermore, at any given time period, patients receiving intravenous administration of furosemide 10 mg were 2.3 times more likely to have ureteral patency confirmed compared with patients receiving normal saline (95% CI 1.59-3.23). There were no adverse events related to administration of intravenous furosemide and no delayed diagnoses of ureteric injury. CONCLUSION: Compared with placebo, intravenous administration of 10 mg furosemide at time of intraoperative cystoscopy resulted in a statistically significantly shorter time to confirmation of ureteral patency, though the clinical significance of this finding is small.

External Use of an Oxidized Regenerated Cellulose Agent in the Treatment of Labial Agglutination in Postmenopausal Women.

BACKGROUND: Vulvovaginal diseases affect women of all ages. Vaginal atrophy and vulvar lichen sclerosus are common etiologies for chronic vulvovaginal pruritus and labial agglutination in both prepubertal and postmenopausal women. CASES: We present two cases of a novel approach in management of symptomatic labial agglutination in postmenopausal women. At the time of surgical intervention, an oxidized regenerated cellulose gauze was sutured in place within the operative field of separation of the labia minora and clitoral hood adhesions. At more than 18-months' follow-up, no recurrence of agglutination has been noted. CONCLUSION: The use of an oxidized regenerated cellulose agent may create an effective barrier to recurrence of labial agglutination in postmenopausal women.

Demonstration of a box-stitch technique for laparoscopic uterosacral ligament suspension.

AIM: We demonstrate a novel box stitch technique of laparoscopic post-hysterectomy uterosacral ligament suspension for apical prolapse in restorative pelvic reconstructive surgery. MATERIAL AND METHODS: We present a case of a 58yo female with symptomatic stage III pelvic organ prolapse with a history of a total abdominal hysterectomy 30 years prior. She strongly desired the usage of no synthetic or biologic mesh for her restorative surgical repair. This video provides a step-by-step guide on how to perform a laparoscopic box stitch as a technique for uterosacral ligament suspension as an apical native tissue option for patients with the need for post hysterectomy apical prolapse. CONCLUSION: This video demonstrates a novel box-stitch technique of laparoscopic post-hysterectomy uterosacral ligament suspension as a native tissue option for minimally invasive reconstructive surgery. The procedure is a reasonable option to address apical prolapse in patients who do not desire or who are unable to have synthetic or biologic mesh placed for restorative reconstructive prolapse surgery.

Evaluation of patient preparedness for surgery: a randomized controlled trial.

BACKGROUND: Patient preparedness for pelvic reconstructive surgery has important implications for patient satisfaction and the perception of improvement after surgery. The ideal method in which to optimally prepare patients for surgery has not been determined. OBJECTIVE: The objective of the study was to evaluate the impact of a preoperative patient education video on patient preparedness prior to sacrocolpopexy as measured by a preoperative preparedness questionnaire. STUDY DESIGN: We performed a single-blind, randomized, stratified clinical trial at a single academic center evaluating the use of a preoperative patient education video as an adjunct to preoperative counseling on patient preparedness. Eligible patients presenting for their preoperative appointment prior to undergoing pelvic reconstructive surgery were randomized to watch a preoperative video vs usual care. Preoperative questionnaires assessing patient preparedness, understanding, perception of time, and actual time spent with a health care team were administered at the end of this visit. The primary outcome was patient preparedness for pelvic reconstructive surgery as measured by a preoperative preparedness questionnaire. Secondary outcomes included actual time spent during the physician-patient encounter, perception of time spent with the health care team, and identification of patient factors associated with patient preparedness. RESULTS: Of the total 100 recruited patients, 52 were randomized to the video group and 48 to the usual-care group. The use of the video did not increase overall patient preparedness (71.1% with video vs 68.8% usual care, P = .79) prior to surgery. The use of the video did not decrease the amount of time spent during the physician-patient encounter (16.9 ± 5.6 min vs 17.1 ± 5.4 min, P = .87). There was a significant association between patient preparedness and perception that the health care team spent sufficient time with the patient (89.5% vs 10.5%; P < .001), but no association was observed between preparedness and actual time spent (17.4 ± 5.4 min vs16.5 ± 5.5 min, P = .47). Those with a history of a previous surgery (82.1% vs 33.3%, P = .002) and those with more significant apical prolapse (0.6 ± 4.6 vs -1.6 ± 3.9, P = .05) were more likely to report feeling prepared for surgery. CONCLUSION: The majority of patients undergoing pelvic surgery at our institution felt prepared prior to undergoing surgery. The use of preoperative education video did not increase overall patient preparedness for surgery. Greater preparedness was associated with patient perception of how much time the health care team spent with the patient but not actual time spent.

Levator Ani Muscle Defects in Patients With Surgical Failure.

INTRODUCTION: The objective of the study was to use a well-described system of measuring levator ani (LA) muscle defects from magnetic resonance images to evaluate whether major defects are correlated to an increased risk of surgical failure. METHODS: A retrospective cohort study performed on patients who underwent laparoscopic uterosacral ligament suspension from 2010 to 2012. Surgical failure was defined as a composite score of anatomic bulge beyond the hymen with sensation of bulge or repeat treatment of prolapse via pessary or surgery by 1-year follow-up. Levator ani muscle defects were graded by a score of 0 (no defect), 1 (<50% muscle bulk missing), 2 (>50% muscle bulk missing), or 3 (complete loss of muscle). Total score is the sum from both graded sides, with 0 classified as having no defect, 1 to 3 classified as having minor defects, and 4 to 6 classified as having major defects. Dichotomous values of LA major defects were compared against dichotomous values of surgical outcomes via a contingency table. Fisher exact test was then performed to correlate major defects to surgical success/failure. P value of less than 0.05 was considered statistically significant. RESULTS: Sixty-six women met the inclusion criteria. Thirteen (19.6%) patients met the criteria for surgical failure at 1 year. Of the 13, 54% (7) had a major defect, and 46% (6) had a minor or no defect (odds ratio, 1.31; 95% confidence interval, 0.39-4.41; P = 0.762). CONCLUSIONS: We did not find a statistical correlation to surgical failure after a laparoscopic uterosacral ligament suspension with LA muscle defects on preoperative magnetic resonance images within this specific patient population.

Social networking and Internet use among pelvic floor patients: a multicenter survey.

BACKGROUND: Internet resources are becoming increasingly important for patients seeking medical knowledge. It is imperative to understand patient use and preferences for using the Internet and social networking websites to optimize patient education. OBJECTIVES: The purpose of this study was to evaluate social networking and Internet use among women with pelvic floor complaints to seek information for their conditions as well as describe the likelihood, preferences, and predictors of website usage. STUDY DESIGN: This was a cross-sectional, multicenter study of women presenting to clinical practices of 10 female pelvic medicine and reconstructive surgery fellowship programs across the United States, affiliated with the Fellows' Pelvic Research Network. New female patients presenting with pelvic floor complaints, including urinary incontinence, pelvic organ prolapse, and fecal incontinence were eligible. Participants completed a 24 item questionnaire designed by the authors to assess demographic information, general Internet use, preferences regarding social networking websites, referral patterns, and resources utilized to learn about their pelvic floor complaints. Internet use was quantified as high (≥4 times/wk), moderate (2-3 times/wk), or minimal (≤1 time/wk). Means were used for normally distributed data and medians for data not meeting this assumption. Fisher's exact and χ2 tests were used to evaluate the associations between variables and Internet use. RESULTS: A total of 282 surveys were analyzed. The majority of participants, 83.3%, were white. The mean age was 55.8 years old. Referrals to urogynecology practices were most frequently from obstetrician/gynecologists (39.9%) and primary care providers (27.8%). Subjects were well distributed geographically, with the largest representation from the South (38.0%). Almost one third (29.9%) were most bothered by prolapse complaints, 22.0% by urgency urinary incontinence, 20.9% by stress urinary incontinence, 14.9% by urgency/frequency symptoms, and 4.1% by fecal incontinence. The majority, 75.0%, described high Internet use, whereas 8.5% moderately and 4.8% minimally used the Internet. Women most often used the Internet for personal motivations including medical research (76.4%), and 42.6% reported Google to be their primary search engine. Despite this, only 4.9% primarily used the Internet to learn about their pelvic floor condition, more commonly consulting an obstetrician-gynecologist for this information (39.4%). The majority (74.1%) held a social networking account, and 45.9% visited these daily. Nearly half, 41.7%, expressed the desire to use social networking websites to learn about their condition. Women <65 years old were significantly more likely to have high Internet use (83.4% vs 68.8%, P = .018) and to desire using social networking websites to learn about their pelvic floor complaint (P = .008). The presenting complaint was not associated with Internet use (P = .905) or the desire to use social networking websites to learn about pelvic floor disorders (P = .201). CONCLUSION: Women presenting to urogynecology practices have high Internet use and a desire to learn about their conditions via social networking websites. Despite this, obstetrician-gynecologists remain a common resource for information. Nonetheless, urogynecology practices and national organizations would likely benefit from increasing their Internet resources for patient education in pelvic floor disorders, though patients should be made aware of available resources.

Estimated levator ani subtended volume: a novel assay for predicting surgical failure after uterosacral ligament suspension.

BACKGROUND: Levator ani muscle complex plays an important role in pelvic support and defects or laxity in this muscle complex contributes to pelvic organ prolapse and recurrence after surgical repair. OBJECTIVE: The purpose of this study was to determine whether estimated levator ani subtended volume can predict surgical outcomes for laparoscopic bilateral uterosacral ligament suspension. STUDY DESIGN: A retrospective cohort study was performed in patients who underwent laparoscopic uterosacral ligament suspension from 2010-2012. Only patients with a preoperative pelvic magnetic resonance image were included. Surgical failure was defined as a composite score that included the presence of anatomic bulge beyond the hymen with sensation of vaginal bulge or repeat treatment for prolapse via pessary or surgery by 1-year follow-up evaluation. Standard protocol pelvic magnetic resonance imaging measurements pubococcygeal line, H-line, and M-line were collected along with the calculation of the width of the levator ani hiatus. Estimated levator ani subtended volume was calculated for each subject. An optimal cutoff point was calculated and compared against categoric values of surgical success/failure. A Fisher exact test, an area under receiver operating characteristics curve, and logistic regression analysis were performed. A probability value of <.05 was considered statistically significant. RESULTS: Ninety-three women underwent laparoscopic bilateral uterosacral ligament suspension during study period. Of these, 66 women had a standardized preoperative pelvic magnetic resonance image per institutional protocol. Thirteen patients (19.6%) met the criteria for surgical failure by 1 year. An optimal cutoff point of 38.5 was calculated by Liu's method for optimization. Among the patients with defined surgical failures, 84.6% (11/13) had an estimated levator ani subtended volume above cutoff point of 38.5. Among the patients with defined surgical success, 39.6% (21/53) had an estimated levator ani subtended volume above the cutoff point (84.6% vs 39.6%; P = .0048) with a significant odds ratio of 8.38 (95% confidence interval, 1.69-41.68; P = .009). An area under receiver operating characteristics curve of 0.725 (95% confidence interval, 0.603-0.847), sensitivity of 84.6% (95% confidence interval, 54.6%-98.1%), and specificity of 60.4% (95% confidence interval, 46%-73.5%) at 38.5 were predictors of surgical success/failure by 1 year. Logistic regression analysis demonstrated no significant confounders among age, body mass index, stage, or parity. CONCLUSIONS: Estimated levator ani subtended volume may predict surgical failure for laparoscopic bilateral uterosacral ligament suspension. Patients with a calculated estimated levator ani subtended volume above 38.5 on a preoperative pelvic magnetic resonance imaging were associated with an increased risk for surgical failure by 1 year, regardless of age, body mass index, stage, or parity. Future investigation that will include repeatability, reliability analysis, and a prospective study is warranted.
