Importance: The comparison between single-incision slings (SISs) and midurethral slings has been documented in the literature, but results vary according to the SIS device.
Objectives: The purpose of this study is to assess whether SIS (Solyx) is noninferior to transobturator (TOT) (Obtryx) sling for treating women with confirmed stress-predominant urinary incontinence.
Study Design: A prospective, parallel, nonblinded, multicenter, noninferiority, randomized controlled study with 114 patients were randomized and followed 6 and 12 months after surgery.
