Introduction And Hypothesis:
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.
