Abstract

ObjectivesTo determine predictive factors for the cure of stress urinary incontinence (SUI) or persisting or de novo overactive bladder syndrome (OAB) after a mid-urethral sling procedure (MUS) for women with SUI, especially for menopausal women. Study designAll women who had consecutively received MUS for SUI between January 2008 and July 2019 in a tertiary referral center were reviewed. Main outcome measuresMultivariable Cox proportional hazards model or logistic regression analysis was used to assess the predictors of cure and persisting or de novo OAB after MUS. ResultsA total of 385 women had undergone MUS, of whom 265 (68.8%) were menopausal. The multivariable Cox proportional hazards model revealed that age (hazard ratio = 1.04), and preoperative detrusor overactivity (hazard ratio = 2.26) were independent predictors of persisting/recurrent SUI. Among the 216 women with preoperative OAB, 109 (50.5%) experienced resolution of their OAB after MUS; and among 169 women without preoperative OAB, twenty-five (14.8%) women developed de novo OAB after MUS (p < 0.0001). Preoperative OAB (hazard ratio = 3.97), small voided volume (hazard ratio = 0.83), and preoperative detrusor overactivity (hazard ratio = 1.62) were predictors of postoperative OAB. In addition, six (1.6%) women had mesh extrusion. Parity (odds ratio = 2.08) was the sole predictor of mesh extrusion. Menopause (hazard ratio = 1.69) was a predictor of postoperative OAB in the univariate analysis. However, menopause was not a predictor of cure or OAB in the multivariable analysis. ConclusionsAge and preoperative detrusor overactivity were independent predictors of persisting/recurrent SUI. In addition, preoperative OAB, small voided volume, and preoperative detrusor overactivity were predictors of postoperative OAB. These findings could serve as a guide for preoperative consultation for MUS.
