OBJECTIVE: To assess stress urinary incontinence (SUI) and other lower urinary tract symptom outcomes in women undergoing repeat midurethral sling procedures compared with those undergoing primary midurethral sling procedures.
METHODS: Cure was defined as responses of “not at all” or “somewhat” to both questions of the SUI subscale of the Urogenital Distress Inventory-6; symptom effect was assessed using the Incontinence Impact Questionnaire-7. Multivariable models were created controlling for baseline Medical Epidemiologic and Social Aspects of Aging questionnaire urge score and Urogenital Distress Inventory-6 stress subscale score.
RESULTS: One thousand three hundred sixteen patients had charts available for review: 135 of 1,316 (10.2%) had undergone prior midurethral sling procedures; 799 of 1,316 (61%) questionnaires were returned, with 92 from those having undergone prior midurethral sling procedures. Median follow-up time was 36.4 months with a range of 11.4–71.5 months. Cure rates were 71% (95% confidence interval [CI] 67.7–74.3%) in the primary midurethral sling group and 54% (95% CI 43.8–64.2%) in the repeat midurethral sling group (P<.001). Women undergoing repeat midurethral sling procedures experienced significantly greater improvement in symptom-specific quality of life (QOL) compared with those undergoing primary midurethral sling procedures (−28.87±37.6 compared with −18.42±32.73, P=.01). Multivariable analyses revealed that women in the repeat midurethral sling group had increased risk of SUI failure (odds ratio 1.7, 95% CI 1.1–2.8).
CONCLUSION: Women undergoing repeat midurethral sling procedures had almost two times the odds of SUI treatment failure but greater improvement in symptom effect on QOL than did those undergoing a primary midurethral sling procedure. This information can help counsel patients regarding their expectations of repeat midurethral sling surgery for recurrent SUI .
LEVEL OF EVIDENCE: II
Women undergoing repeat midurethral sling procedures have higher failure rates but greater improvement in symptom-specific effect on quality of life than do women undergoing primary midurethral sling procedures.
