Our experience with pubovaginal slings in patients with stress urinary incontinence

Abstract

Purpose: Pubovaginal slings successfully treat stress urinary incontinence in women with intrinsic sphincter deficiency. Because of its durability, it has been an attractive procedure in select patients with urethral hypermobility. We examine our experience with pubovaginal sling.

Materials and methods: A total of 150 patients were evaluated for pelvic prolapse and urinary incontinence. An abdominal leak point pressure was determined in all patients. Of patients with type II stress urinary incontinence, 36 patients (80%) underwent additional gynecological procedures at the time of the pubovaginal sling, compared to 29% with intrinsic sphincter deficiency and 33% with coexisting urethral hypermobility and intrinsic sphincter deficiency.

Results: The overall cure rate was 93% with a mean followup of 22 months. At 1 week postoperatively spontaneous voiding was accomplished by 56% of the patients with urethral hypermobility and 57% with intrinsic sphincter deficiency. Only 2.8% of patients required surgical therapy for prolonged urinary retention. De novo urgency/urge incontinence occurred in 19% of women with a 3% incidence of persistent urge incontinence.

Conclusions: Pubovaginal slings are effective and durable. Voiding dysfunction is uncommon and is temporary in most patients.
