TVT versus TVT-O for minimally invasive surgical correction of stress urinary incontinence.

OBJECTIVE The present work describes our experience in surgical correction of stress urinary incontinence, comparing both the TVT and the TVT-O techniques. METHOD Between October 2001 and March 2004, 76 patients underwent the TVT procedure. Between January 2004 and January 2005, 98 surgical corrections of urinary incontinence were carried out using the TVT-O technique. RESULTS Median operative time was 28 minutes for TVT and 7 minutes for TVT-O. Intraoperative complications for TVT occurred in 4 patients (6.6%): urinary bladder perforation in 3 patients (5%, p=0.0228) and parietal peritoneum perforation in 1 case (1.6%). No intraoperative complications took place during TVT-O. Immediate postoperative complications: transient urinary retention in TVT, 2 cases (2.6%) and overcorrection in TVT-O (1%) which was readjusted within 24 hours. There were no late complications after TVT. There were 2 cases (2.04%) with late complications in TVT-O. TVT and TVT-O resulted in correction of incontinence in 100% of the patients. CONCLUSION TVT and TVT-O are two effective techniques for the correction of stress urinary incontinence. TVT-O would seem to be a technique much easier to perform resulting in less intraoperative complications.
