An update on surgical management for stress urinary incontinence

Stress urinary incontinence (SUI) is a common condition for which women often opt for surgical management. Synthetic midurethral slings (MUS) have been the dominant treatment for decades. Single-incision slings (SIS) have been introduced to lower the morbidity associated with trocar passage during MUS placement. Urethral bulking has been used less frequently owing to its lower cure rates. New data have recently emerged in support of single-incision slings (SIS) and urethral bulking with Bulkamid polyacrylamide hydrogel (PAHG).

Several studies with a follow-up ≥10 years have shown stable efficacy and complication rates of retropubic (RMUS) and transobturator (TMUS) midurethral slings over time. SIS products show equivalent efficacy to traditional TMUS and RMUS at up to 3 years of follow-up and can be placed under local anesthesia. While urethral bulking with PAHG results in lower cure rates compared to slings, satisfaction rates are high and responders have sustained improvement at 7 years follow-up.

All three types of available slings, TMUS, RMUS, and SIS, are now considered appropriate surgical options for the treatment of SUI. Although the absence of comparative data precludes a formal recommendation for one injectable over another, urethral bulking with PAHG has favorable long-term results and an excellent safety profile.
