Two-year comparison of tension-free vaginal tape and transobturator tape for female urinary stress incontinence.

Tension-free vaginal tape (TVT) and transobturator tape (TOT) are relatively new, minimally invasive procedures for the management of stress incontinence. All patients with urodynamic stress incontinence who underwent a TVT procedure from April 2003 to March 2005 (n = 76) were compared with all patients who had TOT from September 2004 to August 2006 (n = 73). The overall success rate for TVT was 97.4% and for TOT was 94.5%. Success was defined as no leakage, as reported by the patient at follow-up. Voiding difficulty in the TVT group was 9.2% for <1 week's duration and 2.6% for >1 week's duration, while in the TOT group, it was 4.1% and 1.4%, respectively. Bladder perforation was 1.3% in the TVT group but was 0 (none) in the TOT group. Both TOT and TVT have good success rates with minimal complications, although bladder perforation has a higher incidence rate in the TVT group.
