Evaluation of prolene mesh as a transobturator tape for treatment of female stress urinary incontinence - Abstract

INTRODUCTION: Slings are commonly used to treat female stress urinary incontinence (SUI). Various sling materials have been tried. The objective of this retrospective study was to determine the short-term efficacy, safety, and urodynamic effects of a suburethral sling made of polypropylene mesh and passed through the obturator foramen.

METHODS: The participants were 53 female patients with SUI; 16 (30%) had pure intrinsic sphincter deficiency (ISD) and 37 (70%) had mixed ISD and hypermobility. Preoperative evaluation consisted of history, voiding diary, examination, ascending cystography, urodynamic studies, and routine laboratory investigations. All patients were treated with a polypropylene mesh (Prolene; Ethicon Ltd, Bracknell, UK) suburethral sling. The Prolene mesh was cut into a tape measuring 30 x 1.5 cm and sterilized by autoclave. The mesh was placed at the midurethra and passed through the obturator foramen by Vicryl sutures, loaded on a curved needle that was specially designed to hold the suture. The needle was passed from the outside to the inside. The mesh was anchored to the subcutaneous tissue at the lateral edge of labia majora with Vicryl sutures. One month after surgery, patients had an interview, examination, urine analysis, and pelvic ultrasound to detect residual urine. Urodynamic evaluation was done 3 months postoperatively. Patients were then followed every 3 months through a voiding diary and examination. The mean follow-up period was 18 months.

RESULTS: All procedures were completed with no intraoperative complications, failures, or recurrences of SUI. At the 1-month follow-up, 3 patients (5%) had developed a small erosion of the anterior vaginal wall associated with lower abdominal pain, urgency, dysuria, and urinary tract infection. The patients were managed conservatively with antibiotics and local estrogen cream. At the 3-month follow-up, the erosion healed completely. Three patients (5%) complained of sensory urge incontinence both preoperatively and postoperatively. They were managed with anticholinergics.

CONCLUSION: Preliminary results showed that the suburethral transobturator Prolene mesh sling is a safe, efficient, reproducible, and low-cost technique for treatment of stress urinary incontinence. Complications exist but can be successfully managed.
