Mid-urethral sling surgery was the gold standard for stress urinary incontinence. Our objective was to assess the current outcome (efficacy, adverse events) of women who had been successfully operated upon for SUI by means of a TVT procedure.

We performed a retrospective cohort study including 60 women (mean age 69.4 years) who underwent a successful TVT procedure in a teaching hospital between January 2017 and December 2024. The main outcome measure was the incidence of patient self-reported no leakage. Secondary outcome were change of urodynamic parameter, incidence of de novo overactive bladder symptoms. We carried out a univariate logistic regression analysis to examine the relationship between outcomes and a set of clinical variables

A total 60 women were enrolled with mean age 58. 29 patients were pure stress urinary incontinence and 31 patients had mixed urinary incontinence. The cure rate were 85.7% (MUI) and 77.4% (SUI) separately. 10 patients (15%) had de-novo overactive bladder symptoms. The Urodynamic change showed the decrease of voiding volume (mean difference -114 ml [-162~-67], p<0.0001) and peak flow rate (mean difference: -7 [-10~-4], p<0.0001) after surgery. Age was the risk factor of de novo overactive bladder symptoms (OR: 1.1 [1.0~1.2], p = 0.039).

The effectiveness of mid-urethral sling surgery for women with stress urinary incontinence or mixed urinary incontinence in our hospital was comparable. Age seems to be the only risk factor for de novo overactive bladder symptoms.
