The Role of Obesity in Success and Complications in Patients Undergoing Retropubic Tension-Free Vaginal Tape Surgery

Objectives: The aim of this study was to examine the impact of obesity on the success rate of and complications from retropubic tension-free vaginal tape (TVT) midurethral slings for stress urinary incontinence (SUI). Methods: A retrospective, cohort study was performed on patients with retropubic TVT surgery between 2008 and 2014. Demographic, outcome, and complication data were obtained from electronic medical records and analyzed using logistic regression, analysis of variance, and multivariate regression analysis. Short-term (1-2 weeks) and long-term (2 months) outcomes were measured. Results: Two hundred twenty-seven patients were included; 100 (44%) were of normal weight, 71 (31%) were overweight, and 56 (24%) were obese. Overall SUI cure rates were high, although the obese group had a lower cure rate. Compared with normal weight, overweight patients had a 2.43 times higher odds (P = 0.14) of short-term complaints of persistent SUI, whereas obese patients had a 3.56 times higher odds (P = 0.03). Similar failure rates were seen at 2 months among the groups. Odds of intraoperative complications did not differ between overweight and normal weight (odds ratio [OR], 0.64; P = 0.319) and obese and normal weight (OR, 0.90; P = 0.83) patients. Postoperative complications did not differ between overweight and normal weight (OR, 0.40; P = 0.27) and obese and normal weight (OR, 1.45; P = 0.54) patients. Conclusions: Obese women undergoing retropubic TVT surgery had a 3.56 increased odds of short-term complaints of SUI compared with normal weight patients, but 2-month failure rates were similar. Obese and overweight patients were equally likely to have complications from TVT.
