Identifying Patients With Vesicovaginal Fistula at High Risk of Urinary Incontinence After Surgery.

ABSTRACT: OBJECTIVE:To develop a risk score to identify women with vesicovaginal fistula at high risk of residual urinary incontinence after surgical repair. METHODS:We conducted a prospective cohort study among 401 women undergoing their first vesicovaginal fistula repair at a referral fistula repair center in Lilongwe, Malawi, between September 2011 and December 2014, who returned for follow-up within 120 days of surgery. We used logistic regression to develop a risk score to identify women with a high likelihood of residual urinary incontinence, defined as incontinence grade 2-5 within 120 days of vesicovaginal fistula repair, based on preoperative clinical and demographic characteristics (age, number of years with fistula, human immunodeficiency virus status, body mass index, previous repair surgery at an outside facility, revised Goh classification, Goh vesicovaginal fistula size, circumferential fistula, vaginal scaring, bladder size, and urethral length). The sensitivity, specificity, and positive and negative predictive values of the risk score at each cut point were assessed. RESULTS:Overall, 11 (3%) women had unsuccessful fistula closure. Of those with successful fistula closure (n=372), 85 (23%) experienced residual incontinence. A risk score cut point of 20 had sensitivity of 82% (95% confidence interval [CI] 72-89%) and specificity 63% (95% CI 57-69%) to potentially identify women with residual incontinence. In our population, the positive predictive value for a risk score cut point of 20 or higher was 43% (95% CI 36-51%) and the negative predictive value was 91% (95% CI 86-94%). Forty-eight percent of our study population had a risk score 20 or greater and, therefore, would have been identified for further intervention. CONCLUSION:A risk score of 20 or higher was associated with an increased likelihood of residual incontinence with satisfactory sensitivity and specificity. If validated in alternative settings, the risk score could be used to refer women with a high likelihood of postoperative incontinence to more experienced surgeons.

Project description:ImportanceAmong women and men with severe obesity, evidence for improvement in urinary incontinence beyond the first year after bariatric surgery-induced weight loss is lacking.ObjectivesTo examine change in urinary incontinence before and after bariatric surgery and to identify factors associated with improvement and remission among women and men in the first 3 years after bariatric surgery.Design, setting, and participantsThe Longitudinal Assessment of Bariatric Surgery 2 is an observational cohort study at 10 US hospitals in 6 geographically diverse clinical centers. Participants were recruited between February 21, 2005, and February 17, 2009. Adults undergoing first-time bariatric surgical procedures as part of clinical care by participating surgeons between March 14, 2006, and April 24, 2009, were followed up for 3 years (through October 24, 2012).InterventionParticipants undergoing bariatric surgery completed research assessments before the procedure and annually thereafter.Main outcomes and measuresThe frequency and type of urinary incontinence episodes in the past 3 months were assessed using a validated questionnaire. Prevalent urinary incontinence was defined as at least weekly urinary incontinence episodes, and remission was defined as change from prevalent urinary incontinence at baseline to less than weekly urinary incontinence episodes at follow-up.ResultsOf 2458 participants, 1987 (80.8%) completed baseline and follow-up assessments. At baseline, the median age was 47 years (age range, 18-78 years), the median body mass index was 46 kg/m2 (range, 34-94 kg/m2), and 1565 of 1987 (78.8%) were women. Urinary incontinence was more prevalent among women (49.3%; 95% CI, 46.9%-51.9%) than men (21.8%; 95% CI, 18.2%-26.1%) (P < .001). After a mean 1-year weight loss of 29.5% (95% CI, 29.0%-30.1%) in women and 27.0% (95% CI, 25.9%-28.6%) in men, year 1 urinary incontinence prevalence was significantly lower among women (18.3%; 95% CI, 16.4%-20.4%) and men (9.8%; 95% CI, 7.2%-13.4%) (P < .001 for all). The 3-year prevalence was higher than the 1-year prevalence for both sexes (24.8%; 95% CI, 21.8%-26.5% among women and 12.2%; 95% CI, 9.0%-16.4% among men) but was substantially lower than baseline (P < .001 for all). Weight loss was independently related to urinary incontinence remission (relative risk, 1.08; 95% CI, 1.06-1.10 in women and 1.07; 95% CI, 1.02-1.13 in men) per 5% weight loss, as were younger age and the absence of a severe walking limitation.Conclusions and relevanceAmong women and men with severe obesity, bariatric surgery was associated with substantially reduced urinary incontinence over 3 years. Improvement in urinary incontinence may be an important benefit of bariatric surgery.

Project description:ObjectiveTo identify factors that may contribute to patient satisfaction with outcome in women who received retropubic and transobturator midurethral slings.MethodsSatisfaction was assessed 12 months postsurgery as a planned analysis in 597 participants from a multicenter randomized trial comparing retropubic with transobturator midurethral slings using the Incontinence Surgery Satisfaction Questionnaire. Significantly related variables associated with satisfaction in univariable analyses were entered into multivariable logistic regression models to test their independent association with satisfaction.ResultsOne year after surgery, 264 (88.6%) in the retropubic group and 263 (88.0%) in the transobturator group completed satisfaction questionnaires. Both treatment groups demonstrated a high level of satisfaction with respect to urine leakage (retropubic 85.9% compared with transobturator 90.0%; P=.52), urgency to urinate, frequency of urination, capability of physical activity, social activity, ability to engage in sexual activity, and from an emotional standpoint. Baseline characteristics associated with reduced satisfaction were higher Medical, Epidemiologic, and Social Aspects of Aging Questionnaire urgency subscale scores, detrusor overactivity, and diabetes mellitus. The severity of both objective (frequency of incontinence episodes, pad test weight) and subjective (Incontinence Impact Questionnaire and Urogenital Distress Inventory score) measures of incontinence at baseline and the patients' perceptions of preoperative severity of incontinence and expectations of achieving postoperative cure or improvement were not statistically different between satisfied and unsatisfied patients. In the final multivariable model, satisfaction was associated with overall treatment success (odds ratio [OR] 2.57, 95% confidence interval [CI] 1.29-5.13], greater reduction in Urogenital Distress Inventory (OR 0.97, 95% CI 0.96-0.98) and Incontinence Impact Questionnaire scores (OR 0.99, 95% CI 0.98-0.99), and fewer complications (OR 0.55, 95% CI 0.30-0.99).ConclusionThe high level of satisfaction seen after midurethral sling procedures is associated with greater objective and patient-perceived improvement of stress incontinence and fewer complications.Clinical trial registrationClinicalTrials.gov, www.clinicaltrials.gov, NCT00325039.Level of evidenceII.
