Challenges of Multidimensional Outcome Reporting after Suburethral Mid Urethral Sling Removal

Purpose: We sought to determine the types and frequency of presenting symptoms in women undergoing suburethral mid urethral sling removal to improve outcome reporting after removal. Materials and Methods: Following institutional review board approval women who underwent suburethral mid urethral sling removal of 1 mid urethral sling were evaluated for their presenting symptoms and correlation with the UDI-6 (Urogenital Distress Inventory-Short Form) questionnaire. Demographic data were recorded. Patient reported presenting symptoms were categorized into 5 domains, including storage symptoms, voiding symptoms, pain, recurrent urinary tract infections or urinary incontinence. The UDI-6 was reviewed preoperatively and 6 to 12 months postoperatively. We also calculated an ideal outcome, defined as resolution of incontinence, pain, resumption of sexual activity and no need for further anti-incontinence procedures. Results: A total of 230 women from 2006 to 2017 met study inclusion criteria, including 116 who completed the UDI-6 postoperatively. Of the women 80% had 3 or more presenting symptoms with pain as the most common symptom. The most common combination of symptoms was all 5 domains, which was noted in 46 of the 230 women (20%). An increasing number of symptoms correlated with the total preoperative UDI-6 score. Symptom domains were associated with the corresponding UDI-6 subdomain questions. Domains not covered by the UDI-6, ie recurrent urinary tract infections and dyspareunia, accounted for 27% of reported symptoms. Due to limited data on sexual activity an ideal outcome was reached in 10% of patients but this rate was 40% after sexual activity information was excluded. Conclusions: In this series the presenting symptoms were manifold in women undergoing suburethral mid urethral sling removal. The UDI-6 questionnaire correlated with many of these complaints. It may be used in outcome analysis in conjunction with self-reported symptoms.
