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.
