Abstract

Objective: To compare postoperative pain scores and assess efficacy between an adjustable single-incision sling and a standard transobturator sling for stress urinary incontinence (SUI).

Methods: This single-blinded randomized controlled trial involved 156 women with clinically proven SUI. Women were allocated to receive either an adjustable single-incision or a transobturator sling. The primary outcome was postoperative pain score on a visual analog scale. Secondary outcomes were objective and subjective cure rates at 12 months, symptom bother scores, quality of life, and complications.

Results: The mean pain score in the first week postoperatively was significantly lower at all time points in the adjustable single-incision sling group compared with the transobturator sling group. Maximum difference in pain score was reported on the evening of the day of surgery; median pain score was 1.0 (interquartile range 2.0) in the adjustable sling group and 3.0 (interquartile range 4.5) in the transobturator sling group (Mann Whitney U test P<.001). There was no statistical difference in analgesic use. The objective cure rates in the adjustable single-incision sling and in the transobturator sling group were 90.8% and 88.6% (P=.760), and the subjective cure rates were 77.2% and 72.9% (P=.577), respectively. No difference in the complication rate was found.

Conclusion: An adjustable single-incision sling for the treatment of SUI is associated with lower early postoperative pain scores but shows comparable cure rates with a transobturator at 12 months of follow-up.
