Efficacy and safety of tension-free vaginal tape compared with transobturator tape among obese women with stress urinary incontinence: a retrospective cohort study.

OBJECTIVE:To determine the efficacy and safety of tension-free vaginal tape (TVT) compared with transobturator tape (TOT) in obese women with stress urinary incontinence (SUI). METHODS:We performed a retrospective chart review of patients who underwent insertion of TVT or TOT for stress urinary incontinence between January 2003 and October 2009. Women were excluded if they had had previous surgery for SUI or had a diagnosis of intrinsic sphincter deficiency. RESULTS:One hundred eighty obese women (BMI > 30 kg/m²) with SUI and with follow-up for at least one year were identified (90 had TVT and 90 had TOT). The rates of success on the objective criteria were 91% for the TVT group and 88% for the TOT group (P = 0.46) and 87% versus 80% (P = 0.23) on subjective assessment. CONCLUSION:Our retrospective cohort study demonstrated similar rates of cure for obese women with SUI who underwent insertion of TVT and TOT.
