Abstract

PURPOSE
Sling operation has been known the best treatment of woman with anatomical urinary incontinence(AI) and intrinsic sphincteric deficiency(ISD). We evaluated the clinical outcome of anterior vaginal wall sling as a treatment for stress urinary incontinence.
MATERIALS AND METHODS
Thirty three patients with stress urinary incontinence who treated with anterior vaginal wall sling from October 1995 to March 2000 were analyzed. Patients were evaluated preoperatively with history, physical examination, voiding cystourethrography, evaluation with SEAPI classification and urodynamic study including of Valsalva leak point pressure(VLPP) and maximal urethral closing pressure(MUCP). All patients were assessed for the outcome of the procedure and subjective satisfaction by questionnaires. Surgical outcomes were then analyzed in relation to VLPP , MUCP and subjective SEAPI score. Of the total 33 patients, 26(78.8%) had AI and 7(21.2%) had ISD. According to the Stamey grades, 6(18.2%) were grade I, 23(69.7%) were grade II and 4(12.1%) were grade III.
RESULTS
With a mean follow-up of 42.4 months (range 14 to 66). Urinary incontinence completely disappeared in 20 patients(60.6%), significantly improved in 8 patients(24.2%), failed in 5 patients(15.2%). Complication included urinary retention in two patients, suprapubic pain in two patients, and urge incontinence in two patients. Pre- and postoperative urge incontinence was major factor for failure rate.
CONCLUSIONS
Anterior vaginal sling operation is a simple, safe and effective procedure for treatment of both AI and ISD. The urge incontinence is closely related to success rate.
