Transobturator tape sling for female stress incontinence with polypropylene tape and outside-in procedure: prospective study with 1 year of minimal follow-up and review of transobturator tape sling.

Objectives: To assess the efficacy and safety of a minimally invasive surgical procedure using a polypropylene transobturator tape to treat female stress urinary incontinence during a minimal follow-up of 1 year and to present a review of this technique.

Methods: A total of 206 women with stress urinary incontinence who underwent the transobturator tape procedure in a French multicenter prospective open tracker study, with a minimal follow-up of 1 year (range 12 to 33 months), were assessed. A nonelastic, polypropylene tape was placed under the mid-urethra. The surgical placement technique used a vaginal and transobturator percutaneous approach. Postoperative assessments included clinical examination, cough-stress test (full bladder), uroflowmetry, and postvoid residual urine volume performed after 1, 6, 12, 18, and 24 months.

Results: The mean follow-up was 16 months (range 12 to 33). Of the 206 patients, 79.1% were completely cured, 13% improved, and 7% failed. No vascular, nervous system, or digestive perioperative complications were observed; however, 2.4% of the patients had postoperative urinary retention.

Conclusions: The results of the present study have confirmed the optimal results in stress incontinence previously reported in short-term studies. These results suggest that the transobturator tape procedure is a valuable alternative to the transvaginal tape procedure, with a low rate of complications.
