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.
