Little data are available on the outcome of tension-free obturator tape (TVT-O) procedures in obese and overweight women. We hypothesized that the subjective and objective outcomes of TVT-O in women with a higher body mass index (BMI) would differ from those with a lower BMI. We retrospectively reviewed the records of 129 patients who had undergone TVT-O, stratifying by BMI into normal weight (n = 39), overweight (n = 58), and obese (n = 32) groups. We compared pre- and postoperative evaluations, including subjective and objective outcome of TVT-O, complications, and quality of life assessed by validated questionnaires. The median follow-up was 24 months. There were no significant differences between groups in terms of objective cure rate and subjective success, quality of life scores, or postoperative complications. BMI did not influence the outcome of TVT-O procedures at a median of 24 months after surgery.
