TVT-O in the treatment of stress urinary incontinence： long-term evaluation and urodynamic study

Abstract

Objective To evaluate the long-term outcomes, complications and urodynamie parame- ters of using tension-free vaginal tape-obturator （TVT-O） in the treatment of patients with stress urinary in- continence. Methods Preoperative and postoperative evaluations including urodynamic data and quality of life were performed for 24 patients with stress urinary incontinence who were enrolled and treated with TVT-O between May 2007 and June 2011. Results Patients completed long-term postoperative follow-up from 12 to 60 months after surgery. Twenty-one （87.5%） patients achieved long-term subjective success and 22 （91.7%） achieved objective success. Surgical satisfaction and quality of life was high. Long-term postoperative abdominal leak point pressure of 23 patient was greater than 100 cm H20, and the remaining parameters preoperative and postoperative showed no significant differences. Voiding difficulty and external reflection voding desire were the main long-term complications. Conclusions TVT-O is with few compli- cations and high patient satisfaction. It is a simple, safe and effective procedure for treatment of patients with stress urinary incontinence. Long follow-up period is important for the comprehensive evaluation of TVT-O. Postoperative urodynamic study has significance in complications, diagnosis and evaluation.
