Purpose

We prospectively compared the efficacy and safety of tension-free vaginal tape and transobturator vaginal tape inside-out for female stress urinary incontinence.

MATERIALS AND

Methods:

A total of 120 women with stress urinary incontinence were alternately assigned to the tension-free vaginal tape group (60) or the transobturator vaginal tape inside-out group (60). Preoperative evaluation included urodynamic study and a Korean version of the incontinencequality of life questionnaire. One year after operation the surgical result, patient satisfaction, incontinencequality of life questionnaire, long-term complications and uroflowmetry were evaluated in the 2 groups.

Results:

Patient characteristics were comparable in the 2 groups. Mean +/- SD operative time was significantly shorter in the transobturator vaginal tape inside-out vs the tension-free vaginal tape group (11 +/- 1.4 vs 15 +/- 1.8 minutes). In the transobturator vaginal tape inside-out and the tension-free vaginal tape groups the rates of cure (86.8% and 86.8%), improvement (6.6% and 8.2%) and failure (6.6% and 5.0%, respectively) were similar. Incontinencequality of life questionnaire parameters 1 year after surgery were improved significantly in each group and there was no difference between the 2 groups (p<0.001 and >0.05, respectively). There was no long-term complication in either group. Preoperative urge incontinence resolved in 80% of the tension-free vaginal tape group and in 100% of the transobturator vaginal tape inside-out group. De novo urgency developed in 4 patients (6.6%) in the transobturator vaginal tape inside-out group.

Conclusions:

The tension-free vaginal tape and transobturator vaginal tape inside-out procedures were minimally invasive and similar in operation related morbidity. Transobturator vaginal tape inside-out appeared to be as effective and safe as tension-free vaginal tape for the surgical treatment of stress urinary incontinence in women at 1-year followup.
