The purpose of this study was to report the rate of stress urinary incontinence (SUI) recurrence after sling revision, and to determine predictive factors of SUI recurrence.
We conducted a retrospective cohort study in a single academic center between 2005 and 2022, of patients who underwent sling revision. Four surgical techniques were used for sling revision (loosening, section, partial, and total excision). The primary endpoint was recurrence of SUI at 3 months postoperatively, and the other outcome of interest was the rate of subsequent anti-incontinence surgical procedure.
Sixty-nine patients were included for analysis. SUI recurred in 46.4% of patients. Fifteen patients underwent a subsequent anti-incontinence procedure (21.8%). The time to revision was significantly longer in the group with recurrent SUI (median: 84.5 vs. 44.8 months; p = 0.004). The recurrence rate differed significantly depending on the revision technique: 7.7% after sling loosening, 22.2% after sling section, 60% after partial excision, and 66.7% after complete sling removal (p = 0.001). The risk of SUI recurrence was lower for those whose indication of reoperation was voiding dysfunction (27.3% vs. 66.7%; p = 0.002), and was higher for those who underwent a trans-obturator tap rather than a tension-free vaginal tape revision (68.4% vs. 35.7%; p = 0.02). In multivariate analysis, only the revision technique remained significantly associated with the risk of recurrence of SUI (complete excision vs. section: odds ratio = 4.66; p = 0.04).
The risk of SUI recurrence may differ widely according to the techniques used, and it seems that the less extensive the surgical procedure is, the lower the risk is.
