title: Tension-free vaginal tape versus tension-free vaginal tape obturator in women with stress urinary incontinence.
abstract: BACKGROUND
  To assess the efficacy and complications of tension-free vaginal tape (TVT) versus tension-free vaginal tape obturator in women with urodynamic stress incontinence.
  
  
  METHODS
  Prospective, randomized study. Initially, 91 patients were included in the study and 89 of them were available at 12 months follow-up. Forty-six patients were subjected to classic TVT procedure and 43 to transobturator vaginal tape from inside to outside (TVT-O) operation. There was no significant difference between the groups for age, BMI, menopausal status and prolapse. No patients had cystocele greater than stage I. Subjective and objective cure and improvement rate, mean operative time, hospital stay and complications incidence were assessed.
  
  
  RESULTS
  Mean operative time was significant shorter in the TVT-O group (17.4 +/- 6.9 min) compared to the TVT group (26.7 +/- 8.6 min). There was no significant difference in the duration of hospital stay between two groups. The objective cure rate for TVT group was 89%, the improvement rate was 6.5%, the failure rate was 4.3% and the subjective cure rate 73.9%. The objective cure rate for TVT-O group was 90%, the improvement rate was 7.6%, the failure rate was 2.5% and the subjective cure rate 76.7%. The hemoglobin loss ranged between 1.0 +/- 0.5 g/dl for TVT group and 0.9 +/- 0.4 g/dl for TVT-O group.
  
  
  CONCLUSIONS
  The TVT-O technique presents success rates comparable to the classic TVT method in the short term.
