Long-term postoperative follow-up results of transobturator autologous rectus fascial sling versus transobturator tension-free vaginal tapes for female stress urinary incontinence: Randomized controlled clinical trial.

Abstract

To evaluate the outcomes of a new surgical technique for the treatment of stress urinary incontinence (SUI). This randomized study included 132 index patients from January 2017 to May 2021, 60 applied with autologous facia and 60 with transobturator tension-free vaginal tape (TVT-O). The primary endpoint was dryness (negative stress test and 0 pad use per day) and this was assessed at 3, 6, 12, and 24 months. The secondary endpoints were the International Consultation on Incontinence Questionnaire short form (ICIQ-SF) and the urinary incontinence quality of life (QoL) at 3, 6, 12, and 24 months. The dryness rate at 24 months was 92.4% (49/53) for patients with transobturator autologous rectus fascial sling (TO-AFS) and 94.6% (53/56) for those with TVT-O (p = 0.47). No difference was determined between the TO-AFS and TVT-O groups in respect of the ICIQ-SF and QoL scores at 2 years postoperatively (p = 0.87). There were five postoperative complications in the TO-AFS group (one urinary retention, one hematoma at suprapubic incision line, and three intermittent groin pains) and four in the TVT-O group (four persistent groin pain) (p = 0.98). The objective cure rates of the 24-month outcomes of TO-AFS indicate that this novel surgical technique seems to be a highly effective, safe, and feasible procedure for the treatment of SUI, but further studies including long-term follow-up are mandatory to confirm these preliminary data.
