title: Body mass index as a risk factor for cystotomy during suprapubic placement of mid-urethral slings.
abstract: OBJECTIVE
  This study aims to investigate whether body mass index (BMI) is a risk factor for cystotomy during sling placement via suprapubic approach for stress urinary incontinence.
  
  
  METHODS
  Retrospective chart review was performed for suprapubic mid-urethral sling placement between June 2005 and October 2007. Data collected included demographics, BMI, and history of prior and concomitant procedures. Primary outcome was cystotomy during sling placement.
  
  
  RESULTS
  Of 198 women identified, 129 had a BMI < 30 kg/m2 and 69 had a BMI > or = 30 kg/m2. There were 18 (14.0%) cystotomies in the BMI < 30 kg/m2 group and three (4.3%) in the BMI > or = 30 kg/m2 group (p = 0.04). BMI < 30 kg/m2 remained a risk factor for cystotomy after controlling for confounders (OR 4.63, 95% CI 1.20-17.86), as did prior anti-incontinence surgery (OR 3.55, 95% CI 1.01-12.50).
  
  
  CONCLUSIONS
  BMI < 30 kg/m2 may be a risk factor for cystotomy during sling placement utilizing the suprapubic approach.
