IRIS-Transobturator Tape Procedure for the Treatment of Women with Stress Urinary Incontinence / 대한비뇨기과학회지

ABSTRACT

PURPOSE: We wanted to evaluate the clinical efficacy, safety and satisfaction of patients with IRIS-transobturator tape (TOT) operation for the women suffering with stress urinary incontinence. MATERIALS AND METHODS: 53 women with stress urinary incontinence who underwent the TOT procedure between February 2004 and June 2005 were included in this study. Preoperatively, the patients were evaluated with history taking, a physical examination, a voiding diary, a one-hour pad test, uroflowmetry and the post voided residual urine. The procedure was carried out using a previously established method under local anesthesia for 37 patients and under spinal anesthesia for 16 patients. The post-operative symptoms and patient satisfaction were assessed by questionnaire. RESULTS: The patients' mean age was 49.6 years (average age 35-73 years). The mean follow-up was 10.9 months (average follow-up 3-20 months). The mean operation time was 30.2 minutes (average time 20-50 minutes). The mean duration of the post operative indwelling catheter was 1 hour for local anesthesia and 18 hours (range 14-20 hours) for spinal anesthesia. Of the 53 patients, 49 (92.4%) of the patients were cured and 4 (7.6%) were significantly improved. The postoperative complications were urinary retention in 4 patients, and tape exposure by vaginal erosion in 1 patient. De novo urgency occurred in 1 patient and de novo urge incontinence occurred in 1 patient. CONCLUSIONS: Despite the short term follow-up period, the IRIS-TOT procedure is simple, effective and less invasive for the treatment of stress urinary incontinence in terms of the high success rate and the low complication rates.
