Currently, the midurethral sling (MUS) is widely used as a standard treatment in patients with stress urinary incontinence (SUI). Several studies have reported the failure rate of MUS to be approximately 5%?20%. In general, sling failure can be defined as persistent SUI after surgery or a temporary improvement in incontinence followed by recurrence. Failure is also often considered to include cases requiring secondary surgery due to mesh exposure, postoperative voiding difficulty, de novo urgency/urge incontinence, and severe postoperative pain. Because of the lack of large-scale, high-quality research on this topic, no clear guidelines exist for second-line management. To date, transurethral bulking agent injections, tape shortening, repeat MUS, pubovaginal sling (PVS) using autologous fascia, and Burch colposuspension are available options for second-line surgery. Repeat MUS is the most widely used second-line surgical method at present. Bulking agent injections have lower durability and efficacy than other treatments. Tape shortening demonstrates a relatively low success rate, but comparable outcomes if the period from first treatment to relapse is short. In patients with intrinsic sphincter deficiency, PVS and retropubic (RP) MUS can be considered first as second-line management because of their higher success rate than other treatments. When revision or reoperation is required due to prior mesh-related complications, PVS or colposuspension, which is performed without a synthetic mesh, is appropriate for second-line surgery. For patients with detrusor underactivity, a readjustable sling can be a better option because of the high risk of postoperative voiding dysfunction in PVS or RP slings.
