Evaluation of transobturator tension-free vaginal tapes in the management of women with mixed urinary incontinence: one-year outcomes

Aims to assess the efficacy of transobturator tapes in the management of women with urodynamic mixed urinary incontinence (UI). A secondary analysis of a prospective randomized study; 83 women with mixed UI on urodynamics and predominant stress UI symptoms were recruited and randomly assigned to undergo "outside-in" or inside-out transobturator tapes. Preoperative assessment included urodynamic assessment and completion of validated symptom severity and quality of life (QoL) questionnaires. The primary outcome was patient-reported success rates at 1-year as assessed by the Patient Global Impression of Improvement (very much/much improved). Secondary outcomes included changes in preoperative urgency/urgency incontinence, changes in QoL scores and comparison between the 2 types of transobturator tapes. Seventy-seven women completed 1-year follow-up (outside-in [n=42] vs inside-out [n=35]). The patient-reported success rate and objective cure rate were 75% and 90%, respectively. At 1-year follow-up; 40 women (52%) and 31 women (57.4%) reported cure in their preoperative urgency and urgency incontinence, respectively. A total of 74% reported≥10 point improvement in QoL scores. In women with urodynamic mixed incontinence and predominant stress UI, transobturator tapes were associated with good patient-reported success rate at 1 year. Urgency/ urgency incontinence are cured in over 50% of women
