Purpose: We evaluate the clinical effectiveness of transobturator tension-free vaginal tape procedures in the surgical management of mixed urinary incontinence in women at 3-year followup.

Materials and Methods: In this secondary analysis of a prospective, single-blind, randomized controlled trial 83 of 341 women (24%) with mixed urinary incontinence were randomized to undergo an outside-in (Aris (R) transobturator sling system 42) or inside-out (TVT (TM)-O 41) transobturator tension-free vaginal tape procedure. Patients were contacted by postal questionnaire at a minimum of 3 years postoperatively. The primary outcome was the patient reported success rate, defined as very much improved/much improved on the PGI-I (Patient Global Impression of Improvement). Secondary outcomes included improvement in quality of life, impact on preoperative urgency/urgency incontinence and repeat surgical treatment for stress urinary incontinence. Outcomes at 3 years were compared between groups (outside-in vs inside-out) and to 1-year outcomes. Analysis was performed using SPSS (R) version 20 with significance levels set at p = 0.05.

Results: A total of 66 women with mixed urinary incontinence completed the 3-year followup (outside-in 35 vs inside-out 31). In each group 2 women underwent further continence surgery. The patient reported success rate was 73.8% with no significant differences between the groups (OR 1.035, 95% CI 0.342-3.134, p = 0.951). Overall 34 (50.1%) and 26 women (56.5%) reported cure of preoperative urgency and urgency incontinence, respectively, and 52 women (86.7%) had a clinically significant improvement in quality of life (18 points or more in total KHQ [King's Health Questionnaire] score) compared to baseline.

Conclusions: Transobturator tape procedures are associated with a good (73.8%) patient reported success rate at a minimum of 3 years of followup in the surgical management of mixed urinary incontinence in women with predominant stress urinary incontinence symptoms. Nearly half of the women reported cure of urgency/urgency incontinence.
