Two-year Follow Up of IRIS Procedure for Surgical Treatment of Female Stress Urinary Incontinence

ABSTRACT

PURPOSE: To assess the efficacy and safety of a IRIS(innovative replacement of incontinence surgery) procedure for surgical treatment of stress urinary incontinence in women during the follow-up of 2 years. MATERIALS AND METHODS: From March 2003 to March 2004, 48 women with stress urinary incontinence underwent a IRIS procedure under local, spinal or general anesthesia. Post-operative evaluation was carried out after 1 month, 12 months and 24 months. The mean age was 51.1+/-11.0 years and mean follow-up period was 32.1+/-3.8 months. Operation time, success rate and patient's satisfaction, perioperative and postoperative complications were evaluated. RESULTS: The mean operation time was 24.46+/-1.95 minutes and mean hospital stay was 1.77+/-0.75 days. The success rates were 95.8%(cured 79.2%, improved 16.7%) and 93.8%(cured 75.0%, improved 18.8%), at the 1 and 2-year follow-up, respectively. The satisfaction rates were 91.7% at 1-year follow-up and persisted at 2-year follow-up. There were no serious or long-term complications related to the procedure, and no significant changes in the postoperative outcome over time. CONCLUSION: Our results demonstrate that the IRIS procedure is as safe and effective as TVT procedure for the treatment of female stress urinary incontinence, although longer follow-up is necessary to determine long-term effect.
