Management of post-operative urinary incontinence after midurethral sling explantation for pelvic or perineal pain.

INTRODUCTION AND HYPOTHESIS

The objective was to report the management of post-operative urinary incontinence after midurethral sling (MUS) revision for chronic pelvic pain (CPP), and to report functional outcomes.

METHODS

From November 2004 to February 2018, a total of 89 women who underwent removal or section of MUS for CPP, were enrolled. Patients were divided into the transobturator tape (TOT) group (50 patients) and the tension-free vaginal tape (TVT) group (37 patients); 2 patients had had both slings implanted. We report the rate of stress urinary incontinence (SUI) recurrence, the rate of de novo urge urinary incontinence (UUI), the need for subsequent SUI or UUI surgery, and functional outcomes (pain and continence).

RESULTS

Median follow-up was 41.4 months [0.9-138.8]. SUI recurrence or de novo UUI occurred in 52 cases (58.4%): 19 (51.3%) patients in the TVT group, 31 (62%) in the TOT group, and both patients (100%) who underwent total removal of both slings. Among patients with SUI recurrence or de novo UUI, 39 (75%) had pain relief after sling removal. Seventeen patients (32.6%) refused any treatment, 14 (26.9%) were cured with conservative therapy, and 21 (40.3%) underwent SUI or UUI surgery. One patient had de novo pelvic pain after reoperation. The overall continence rate for all patients who underwent sling revision was 82% (73 out of 89) at the last follow-up.

CONCLUSION

After MUS revision for CPP, post-operative UI may occur in 58.4% of patients, of which, one-fourth may be managed with conservative measures only. Forty percent of them had redo surgery with a low risk of pain recurrence and a high rate of urinary continence.
