Lee, Lee, and Kim: Clinical Outcome of the Tension-free Vaginal Tape Procedure for Treating Women with Urinary Incontinence (the 2-year Follow Up): Comparison between Stress Urinary Incontinence and Mixed Urinary Incontinence

Abstract

Purpose

We evaluated and compared the outcomes between stress urinary incontinence (SUI) and mixed urinary incontinence (MUI) for those patients who had undergone a tension-free vaginal tape (TVT) procedure.

Materials and Methods

Patients were categorized into the SUI (43 patients) and MUI (28 patients) groups. The preoperative evaluations included a comprehensive medical history, physical examination and urodynamic study that included determining the Valsalva leak point pressure (VLPP). Further, we asked about lower urianry tract symptoms (LUTSs) with using a female bladder questionnaire. After treatment, the same questionnaires were repeated. The objective and subjective success rate were evaluated during the postoperative period.

Results

For the operation outcome results, in SUI group there were 37 cases of cure (86.0%) and 4 cases of improvement (9.3%), and in MUI group there were 21 cases of cure (75.0%) and 4 cases of improvement (14.3%) (p>0.05). The operation satisfaction rate of patients was 88.4% in the SUI group and 82.2% in the MUI group (p>0.05). The objective success rate and satisfaction rate of the SUI patients did not significantly differ from the women with MUI. Also, these results show that the TVT procedure improves some LUTSs in both groups of patients.

Conclusions

We consider the TVT procedure to be an effective treatment not only for SUI, but also for MUI.
