To identify and compare long-term predictors for 'surgical failures' in matched groups of Midurethral sling (MUS) and Burch colposuspension (BC).
A secondary analysis of patients with urodynamic stress incontinence who were treated either by open BC or retropubic MUS. The study had a cohort of 1344 women with a ratio of 1:3 (BC:MUS). We defined surgical success or failure by combining Patient Reported Outcome Measures and the need for repeat surgery. Risk factors for failure identified by multivariate analysis.
Of the 1344 women included, 336 had BC and 1008 had MUS. Patients were followed-up for 13.1 and 10.1 years, and the rate of failure was 22% and 20%, for BC and MUS, respectively (p=0.35). Significant predictors for MUS failure were BMI>30, preoperative anticholinergic medication use, smoking, diabetes, and previous surgery for incontinence (Hazard ratio (HR) 3.6, 2.6, 2.5, 1.8, 2.3, respectively). BMI>25, preoperative use of anticholinergic medication, age>60, previous surgery for incontinence, and loss of follow-up>5 years (HR: 3.2, 2.8, 2.6, 2.5, 2.1, respectively), were significant predictors of BC failure.
This study shows similar predictors for surgical failure for BC and MUS, with high BMI, mixed urinary incontinence and previous continence procedures being the most important.
