Sling plication for recurrent stress urinary incontinence.

ABSTRACT

OBJECTIVES: Management of recurrent stress urinary incontinence (SUI) after synthetic mid-urethral sling placement is a challenging clinical dilemma. This case series describes a safe, minimally invasive treatment option for recurrent SUI after failure of the primary mid-urethral sling procedure. METHODS: Twenty women with recurrent SUI after previous synthetic mid-urethral sling placement underwent plication of the sling with 2-0 polyester suture under intravenous sedation with an intra-operative cough stress test between December 2004 and December 2008. A retrospective chart review was performed to obtain pertinent preoperative and postoperative data. RESULTS: Nine of the patients had prior retropubic synthetic mid-urethral slings. The other 11 women had transobturator mid-urethral slings, 10 of whom had slings via the outside-in approach and 1 had a single-incision mini-sling placed. The mean patient age was 59.8 years (range 38-83 years). Sling plication was performed at a median of 159.5 days after initial sling placement (range 26-2090 days). Overall 85% of patients had subjective improvement in SUI after sling plication with a median follow-up of 54.5 days (range 29-972 days). Those patients with prior retropubic slings had a 100% improvement rate compared to 72% improvement with prior obturator slings (P = 0.22). The subjective cure rate was 65%, 88% for the retropubic slings and 45% for the transobturator slings (P = 0.07). There were no complications. CONCLUSIONS: Midline plication of previously placed synthetic mid-urethral slings is a safe and effective method of treating recurrent SUI.
