title: Body mass index and outcome of tension-free vaginal tape.
abstract: OBJECTIVE
  To assess the effectiveness of tension-free vaginal tape (TVT) in women with high body mass indices (BMIs).
  
  
  METHODS
  Thirty-eight consecutive patients with BMIs exceeding 30 who underwent tension-free vaginal tape were compared with 149 consecutive patients with BMIs of 30 or less who underwent the same procedure. Body mass index was calculated pre-operatively and at follow-up. Women were classified as being of normal weight (BMI 20-25), overweight (BMI 26-30), or obese (BMI >30). Patient characteristics, operative and post-operative complications, reported continence rates were analyzed according to BMI.
  
  
  RESULTS
  There were no significant differences between groups in terms of age, parity, menopausal status, previous surgery, type and degree of incontinence. Estimated blood loss, operative times, bladder injuries, post-operative urgency and voiding disorders did not differ significantly between women with high BMIs and those with low BMIs. Women with BMIs exceeding 30 had a significantly higher incidence of post-operative urge urinary incontinence (17.9 versus 3.4 and 6.4% p = 0.02) without any effects on the objective and subjective cure rates (82 versus 88.7 and 93% p = 0.1, 71.7 versus 72.1 and 74% p = 0.9).
  
  
  CONCLUSIONS
  We did not find pre-operative obesity to be a risk factor for failure of tension-free vaginal tape.
