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

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 patients̀ 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. (J.
