Suprapubic sling adjustment: minimally invasive method of curing recurrent stress incontinence after sling surgery

PURPOSE: Recurrent stress urinary incontinence after sling surgery is a complex problem. A minimally invasive method of correcting recurrent stress urinary incontinence after pubovaginal sling surgery is described. MATERIALS AND METHODS: We performed suprapubic sling adjustment in 10 women with recurrent stress urinary incontinence after sling surgery. Of these 10 women 4 had received antibacterial polytetrafluoroethylene patch sling, 3 an autologous dermis patch sling and 3 an autologous rectus fascia patch sling but stress incontinence recurred. To correct recurrent incontinence, a pubovaginal sling was revised by adjusting the sling tension suprapubically with the aid of a cotton swab test and bladder leak test. RESULTS: Mean followup was 13 months (range 8 to 28). Of the 10 women 9 became completely dry and 1 was greatly improved. One patient who had persistent stress incontinence generated an abdominal leak point pressure of 189 cm. H(2)O compared to a preoperative pressure of 120 cm. H(2)O. The incidence of de novo urge incontinence was 2% (2 of 10 cases). Mean resting cotton swab angle was (+) 20 and (+) 5 degrees, and mean Valsalva cotton swab angle was (+) 40 and (+) 5 preoperatively and postoperatively. Mean pad use decreased from 3 pads to less than 1 pad a day. Mean self-reported satisfaction score was 9 (range 8 to 10) on a visual analog scale. CONCLUSIONS: Pubovaginal slings may be revised safely with excellent results. Adjusting the sling tension suprapubically is a minimally invasive technique. Suprapubic sling adjustment may be performed as an intermediary step before resorting to a complete sling takedown/revision.
