Purpose: We wanted to identify factors predicting persistent urge urinary incontinence (UUI) after the transobturator tape (TOT) procedure in patients with mixed urinary incontinence (MUI).
Materials and Methods: Of 293 patients who underwent a TOT procedure from May 2007 to August 2010, 175 MUI patients had at least one 6-month follow-up visit. Preoperative evaluations including history taking, physical examination, urinalysis, urine culture, uroflowmetry, postvoid residual (PVR), urodynamic studies (UDS), and symptom questionnaire were performed. After the operation, surgical outcome and patient satisfaction were assessed by symptom questionnaire, uroflowmetry, PVR, and stress test. Statistical analysis was carried out to determine the possible factors influencing persistent UUI after the TOT procedure.
Results: Of 175 patients with MUI, 51 (29.1%) had persistent UUI after the TOT procedure. In a univariate analysis, age (p=0.012) and previous anticholinergic use (p=0.040) were found to be associated with persistent UUI. However, only age (adjusted odds ratio, 3.317; 95% confidence interval, 1.015-12.060; p=0.036) was an independent risk factor in the multivariate analysis.
Conclusions: Our findings suggested that women who are older than 65 years may have an increased likelihood of persistent UUI after a TOT procedure. Clinicians should consider the possibility of persistent postoperative UUI in elderly women with mixed incontinence.
