Abstract

PURPOSE: Sling operation has been performed mainly in urinary incontinence patients with intrinsic sphincteric deficiency. Recently it has been widely used for the correction of various types of stress urinar y incontinence patients. There are three types of sling materials, autologous substance, homologous substance and synthetic substance. Some urologists prefer to use of synthetic substance than autologous substance because of its convenience. We had perform sling operation with Mersilene mesh in 24 patients and evaluated its efficacy.
MATERIALS AND METHODS
We reviewed 24 patients who had undergone sling operation and had been followed up more than one year. Mean age of these patients was 54.3 years and mean duration of symptom was 8.5 years. By the Blaivas classification, 7 were typeI, 10 were type IIa, 4 were type IIb, and 3 were type III. All patients were assessed for operative time, length of hospital stay, postoperative residual urine volume, morbidity, and complications.
RESULTS
Mean operating time was 67 minutes and mean postoperative hospital stay was 5.8 days. Postoperative urethral Foley catheter was kept for 1 to 2 days. Twenty three out of 24 patients were free of symptom after the operation. Mean duration of clean intermittent catheterization was 2 days. As a complication, iatrogenic bladder rupture occurred in one patient during the dissection of anterior vaginal wall, urge incontinence developed in one patient, and urianry retention requring urethrolysis developed in one patients. There was no recurrence of incontinence during observational period, and the overall improvement was found in 23 patients (96%).
CONCLUSIONS
Sling operation using Mersilene mesh was thought to be an effective treatment for stress urinary incontinence not only in the intrinsic sphincter deficiency but also for patients who had previous intra-pelvic surgery and recurred patients after anti-incontinence surgery in variable stress urinary incontinence.
