No incision and tension-free vaginal sling for stress urinary incontinence: The role of knotless barbed suture.

Midurethral mesh sling is the most performed incontinence procedure. This hypotheses propose knotless barbed suture could be positioned as a tension-free trans-vaginal sling under the mid-urethra without vaginal incision. Knotless suture sling support and stabilize mid-urethra when intraabdominal pressure increase. This procedure is designed to replace midurethral mesh sling operation, aiming at reducing complications. It is completed in a similar way with retropubic mesh sling procedure, and less invasive. This involve the passage of fine needle from suprapubic skin to midurethral vaginal wall, and knotless suture passing through in fine needle as a U shape. The foundational promises for this hypothesis pertain to two clinical facts: midurethral sling procedure is a gold standard treatment, and the knotless suture offer superior tissue holding or fixation strength originated from the unique barbed design.
