Abstract

Aims: The primary objectives were to describe the rate of repeat surgery for stress urinary incontinence (SUI) after release of an obstructing synthetic mid-urethral sling (MUS) and to evaluate the effect of time from sling placement to sling release on repeat surgery rates. The secondary objective was to assess rates of recurrent and persistent SUI. Methods: This is a retrospective review of women who underwent synthetic MUS release (incision or excision of segment of sling) from 2005-2013. SUI rates and repeat surgery were ascertained by patient report and urinary distress inventory (UDI-6) questionnaire responses. Data analysis included descriptive statistics and multivariable logistic regression analysis. Results: 107 patients were included. Median time to sling release was 22 months (IQR 5-49 months). 43.2% were transobturator slings. 15/107 patients (14%) underwent repeat surgery for SUI. On multivariable analysis, women were significantly less likely to undergo repeat surgery for SUI when sling release was performed >24 months after initial sling surgery (OR 0.12, 95% CI 0.02-0.85, P=0.03) compared to release within 3 months. 49% and 77% reported recurrent and persistent SUI after sling release, of which 83% were significantly bothered. Conclusion: The repeat surgery rate for SUI was 14%. The rate of recurrent SUI was 49%. Most of these women were significantly bothered. On multivariate analysis, longer interval to sling release was associated with decreased likelihood of repeat surgery for SUI. The reason for a low repeat surgery rate for SUI despite a high rate of bothersome SUI should be explored in future studies.
