Body Mass Index Based Evaluation of 6-Year Outcomes after Transobturator Tension-Free Vaginal Tape for Female Urinary Incontinence

Abstract

Introduction

The long-term results will be presented according to the body mass index (BMI) rates for transobturator tension-free vaginal.

Methods

Three hundred nineteen female patients were evaluated (2008-2014). Their incontinence was classified according to the Stamey classification. The International Consultation on Incontinence Questionnaire-Short form was filled in before and after surgery. The Pelvic Organ Prolapse quantification system was utilized. The Female Sexual Function Index and the International Index of Erectile Functions were asked to be filled in. Their satisfaction level was assessed in the sixth year with the modified Clavien classification system. BMI cut-off points for public health action for the Asian population were adopted in the present study as follows: 18.5-23.0 kg/m² (normal), 23.1-27.4 kg/m² (high) and at least 27.5 kg/m² (obese), respectively.

Results

The median success rate on the 12^th month was calculated as 81.25% in the follow-ups after TOT; it was observed that the median success rate after 72 months decreased to 79.15%. Significant improvements were observed in the Female Sexual Function Index and the Index of Erectile Dysfunction. The objective cure rates detected according to normal, high and obese BMI rates, respectively, were 93.1%, 75.9% and 81.4%, while the patient satisfaction rates were 83.3%, 81.3% and 83.1%, respectively.

Conclusions

It was observed that the objective and subjective patient satisfaction rates were very good in the long term in all BMI groups. No statistically significant differences were observed in perioperative complication rate, 6-year success rates and patient satisfaction among the three different BMI groups in the long term.
