ABSTRACT
In 2006, the single-incision synthetic midurethral sling (MUS) was introduced as a modification to traditional retropubic and transobturator muss. These slings were designed to require less dissection in the midurethral area without the need to make additional incisions suprapubically or in the groin. They are placed entirely through an incision in the vagina having no exit point. They were designed to minimize the risk of bladder perforation associated with traditional retropubic mus and the risk of groin discomfort or other issues related to the inner thigh associated with passage of transobturator slings through the obturator membrane and adductor compartment. Single-incision minislings are anchored into the obturator internus muscles or connective tissues of the endopelvic fascia of the retropubic space behind the pubic bone, and more recently, some are anchored directly into the obturator membrane.
