The Marlex sling operation for the treatment of recurrent stress urinary incontinence: a 16-year review

Abstract

Between 1968 and 1983, 281 patients with recurrent stress urinary incontinence and nine patients with primary stress urinary incontinence were treated with a two-team (suprapubic vaginal) Marlex urethral sling operation. Selection was based on the patient's history and the clinical demonstration of an anatomic defect in the closure mechanism of the urethra. The operative technique as described in 1970 remains unchanged. The bladder neck is released from the scar and replaced in a midretropubic position on a hammock of Marlex mesh attached to Cooper's ligaments. Patients with a sloughed urethra had a sling operation in conjunction with the reconstruction of a neourethra. The overall success rate based on a minimum 5-year follow-up of 208 patients was 77.4%. There was a high failure rate in the sloughed urethra group. Significant overall complications include bladder neck obstruction and chronic cystitis.
