Effects of a Modified Tension-Free Vaginal Tape-Obturator on Female Stress Urinary Incontinence With Slight Anterior Vaginal Prolapse

Abstract

Objective To investigate effects of a modified tension-free vaginal tape-obturator(TVT-O)on treating female stress urinary incontinence(SUI)with slight anterior vaginal prolapse. Methods 28 females with stress urinary incontinence accepted a modified tension-free vaginal tape- obturator surgery by suspending mid-urethra, including 13 cases with anterior vaginal prolapse(11 cases were slight,2 cases were midrange), and 15 cases with pure stress urinary incontinence. Results All patients showed no stress urinary incontinence symptoms completely after the modified tension-free vaginal tape-obturator surgery, with average operation time of 20 minutes, and average intraoperative hemorrhage volume was 40 mL. A 6-month follow-up of 27 patients revealed no recurrence, and previous slight anterior vaginal prolapse in 10 patients become less prominent, while in 2 patients improved significantly. Conclusion The modified tension-free vaginal tape-obturator surgery is effective, minimally invasive, less complicated, and suitable for female stress urinary incontinence with slight anterior vaginal prolapse patients.
