Pain after midurethral sling; the underestimated role of mesh removal

The primary aim of this study was to evaluate the results of midurethral sling (MUS) removal in women who have pain as their single complication of MUS.

We performed a retrospective chart study supplemented with a cross sectional questionnaire. Women who underwent MUS removal for pain as the solitary reason for removal between 2004 and 2018 were included. Primary outcome was change in pain levels assessed by the visual analogue scale (VAS) pain score (range 0-10). Secondary outcome was the recurrence of stress urinary incontinence (SUI).

Twenty-six of 31 patients returned the questionnaire. Median medical file follow-up was 12 months (range 2-66) and 25 months (range 5-104) regarding questionnaires. VAS pain score dropped from 7.8 (SD 1.9) at baseline to 4.5 (SD 3.2) at follow-up (p <.00). Seven (23%) patients were pain-free. Patients undergoing partial vaginal resection (n = 6) had a VAS pain score decrease of 4.7 (p = .02) versus 2.7 (p = .02) for complete vaginal removal (n = 14). Twenty-three (89%) patients experienced SUI at follow-up, whereof 10 (45%) reported (almost) no incidents of SUI.

MUS removal is a viable and safe option with a significant drop in VAS pain score in patients with chronic pain after MUS placement. A post-operative increase of SUI and a possible renewed wish for SUI treatment have to be considered. This should not be a reason to refrain from information and/or referral for surgical removal.
