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

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.

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.

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.

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.
