Stress urinary incontinence (SUI) is a common condition affecting up to 50% of women in developed countries, with the risk of requiring surgery of about 4%.1,2 Surgical treatment is indicated when conservative management fails.3 Many types of surgery have been performed over the years. To date, mid-urethral slings are considered the first option because of high efficacy rates.4 Different synthetic sling procedures are available. Single-incision slings (SISs) were introduced in 2006 with the purpose to decrease the risk of complications including visceral injury, major bleeding, infection, and neurological pain.5,6 SISs showed cure rates comparable with standard tapes in the short-term, with efficacy unaffected by age, body mass index (BMI), obstetrical history, and proper bilateral anchoring on obturator membranes.5,7-9 Nevertheless, there is a lack of evidence about long-term outcomes.
