title: TVT compared with TVT-O and TOT: results from the Norwegian National Incontinence Registry.
abstract: OBJECTIVE
  The aim of this study is to compare the outcome and complication rates of the tension-free vaginal tape (TVT) operations with the transobturator vaginal tape (TVT-O and TOT) operations in the treatment of urinary stress incontinence.
  
  
  METHODS
  This is a multicenter, prospective cohort study. Preoperative and postoperative assessments included a validated Stress and Urge Incontinence Questionnaire, a 24-h pad test, and a standardized stress test.
  
  
  RESULTS
  The study included 5,942 women--4,281 women had a TVT operation and 731 and 373 women had TVT-O and TOT operations, respectively. Median follow-up time was 8 months. Women in the TVT group had less leakage during stress test and fewer subjective stress incontinence symptoms, and were more satisfied with the operation compared with the women in TVT-O and TOT groups, but more complications were reported after TVT operation.
  
  
  CONCLUSIONS
  The TVT operation is more efficient than TVT-O and TOT operations in treating stress incontinent women.
