A Comparative Study of the Tension-free Vaginal Tape and Transobturator Vaginal Tape Inside-out for the Surgical Treatment of Female Stress Urinary Incontinence

ABSTRACT

PURPOSE: We compared the preoperative with the postoperative outcomes between tension-free vaginal tape (TVT) and transobturator vaginal tape inside-out(TVT-O) for the surgical treatment of female stress urinary incontinence MATERIALS AND METHODS: From January 2003 to December 2005, 72 women, one is TVT group(n=52) and the other is TVT-O group(n=20), after operation following were assigned. The preoperative and postoperative evaluations analysis and urodynamic study and Korean version of I-QoL, surgical outcomes, complications and uroflowmetry were analysed. RESULTS: All outcomes included the patients`states, incontinence quality of life(I-QoL)(p=0.013), the success rate of the cure(p=0.003) and the rate of the patient satisfaction(p=0.001) were not comparable statistically between two groups and there are no differences and no long-term complications such as bladder perforation or prolonged voiding difficulty. Preoperative and postoperative uroflowmetry was similar between the two groups. Mean operation time(TVT 15.6 min, TVT-O 13.2 min) was significantly shorter in TVT-O than in TVT. CONCLUSION: The observation of 1-year following-up shows the equally effectiveness between two groups(TVT and TVT-O) as the surgical treatment of stress urinary incontinence.
