Tape shortening for recurrent stress urinary incontinence after transobturator tape sling: 3-year follow-up results

Abstract

Purpose: Recently, as the number of transobturator tape (TOT) procedures has increased, recurrence after this procedure has been frequently reported. However, there are no standard guidelines for treatment. We describe our experience with shortening the previously implanted tape in patients with recurrent stress urinary incontinence after the TOT procedure. Materials and Methods: We enrolled 10 women who underwent shortening of the previously implanted tape and were followed up for 3 years. Shortening of the previously implanted tape was done by a figure-eight suture with 1-0 Prolene. One year after TOT shortening, we investigated continence status, patient satisfaction by means of a questionnaire, maximal flow rate (Qmax), and postvoid residual urine volume. Three years after TOT shortening, we evaluated continence status and patient satisfaction. Results: The mean period of TOT shortening was 4.2 months (range, 1-12 months) after the TOT procedure. One year after TOT shortening, 7 patients showed complete dryness, 2 patients showed improvement, and 1 patient reported failure. Eight patients were very satisfied or satisfied with the 1-year result after TOT shortening. The mean preoperative and postoperative Qmax were 23.8 and 26.7ml/s, respectively, and there was no significant difference. Three years after TOT shortening, 6 patients showed complete dryness, 2 patients showed improvement, and 2 patients reported failure. Among them,1 had failed from 1 year after TOT shortening and the other had shown 1 year of complete dryness. Eight patients were very satisfied or satisfied and 2 patients were dissatisfied with the 3-year result after TOT shortening. Conclusion: Most of the patients who underwent TOT shortening reported satisfaction as well as improvement of incontinence after a 3-year follow up. Therefore, we suggest that TOT shortening may be recommended primarily in patients with recurrent stress urinary incontinence after the TOT sling procedure.
