International audience. Introduction and hypothesis: Bladder outlet obstruction (BOO) is a common occurrence after midurethral sling (MUS) insertion and can result in acute or chronic urinary retention or de novo lower urinary tract symptoms (LUTS). However, the management of BOO after MUS is not standardised. The objective of this study was to compare two therapeutic strategies for suspected BOO after MUS. Methods: Patients who had surgical revision for voiding dysfunction with a post-void residual (PVR) ≥100 ml after MUS in five centres between 2005 and 2020 were included in a retrospective study. Patients were divided into two groups: early sling loosening (EL) vs delayed section/excision of the sling (DS). Results: Seventy patients were included: 38 in the EL group and 32 in the DS group. The postoperative complication rate was comparable in both groups (10.5% vs 12.5%; p = 0.99). At 3 months, the rate of withdrawal from self-catheterisation was similar in the two groups (92.1% vs 100%; p = 0.25) as was the PVR (57.5 vs 63.5 ml; p = 0.09). After a median follow-up of 9 months, there were significantly more patients with resolved voiding dysfunction in the EL group (63.2% vs 31.3%; p = 0.01). The rate of persistent/recurrent stress urinary incontinence (SUI) was higher in the DS group (21% vs 43.7%; p = 0.04). In multivariate analysis, the main predictive factor of recurrent SUI was DS (OR 2.87, 95% CI 1.01–8.60, p = 0.048). Conclusions: Early loosening of MUS in the case of postoperative voiding dysfunction offers better efficacy than DS of the sling, with a lower risk of recurrent/persistent SUI.
