American investigators suggest that a prophylactic midurethral sling inserted during vaginal prolapse surgery appears to lower urinary incontinence rates at 3 and 12 months. Among women who received the sling, the urinary incontinence rates at 3 and 12 months were 23.6% and 27.3%, respectively, com­pared with 49.4% and 43.9% rates for women who received sham incisions during surgery.
