Open vs. Robot-Assisted Artificial Urinary Sphincter Implantation in Women with Stress Urinary Incontinence: A...

Area of Science:

• Urology
• Minimally Invasive Surgery
• Female Pelvic Medicine

Background:

• Artificial urinary sphincter (AUS) implantation is a treatment for stress urinary incontinence (SUI) due to intrinsic sphincter deficiency (ISD).
• Open AUS implantation presents technical challenges and risks, limiting its widespread use.
• Robotic-assisted surgery offers a potential alternative, but comparative data with open procedures are scarce.

Purpose of the Study:

• To compare the outcomes of robot-assisted versus open AUS implantation in women with SUI secondary to ISD.
• To evaluate complication rates, perioperative parameters, and functional results between the two surgical approaches.

Main Methods:

• Retrospective analysis of 135 female patients undergoing open or robot-assisted AUS implantation (2006-2020) across 12 centers.
• Primary outcome: 30-day complication rate (Clavien-Dindo Classification).
• Secondary outcomes: Perioperative metrics, functional continence rates, explantation, and revision rates.

Main Results:

• Robot-assisted group (71 patients) had significantly lower intraoperative (12.7% vs 27.4%) and postoperative (15.5% vs 46.8%) complication rates than the open group (64 patients).
• Higher continence rates (83.3% vs 62.3%) and superior 1-year explantation-free survival (98.6% vs 78.3%) were observed in the robotic group.
• The open group experienced higher explantation (27.4% vs 1.4%) and revision (17.5% vs 5.6%) rates.

Conclusions:

• Robot-assisted AUS implantation is associated with reduced perioperative morbidity compared to open surgery.
• Robotic approach demonstrates improved functional outcomes, including higher continence rates and lower explantation rates.
• Robot-assisted surgery represents a promising advancement for treating SUI in women with ISD.
