The artificial urinary sphincter (AS 800): experience in 166 consecutive patients

Area of Science:

• Urology
• Medical Devices
• Surgical Innovation

Background:

• Urinary incontinence affects a significant patient population, necessitating effective treatment options.
• The artificial urinary sphincter (AUS) is a recognized solution for managing severe urinary incontinence.
• Evaluating the performance and safety of specific AUS models is crucial for clinical practice.

Purpose of the Study:

• To assess the efficacy and safety of the artificial urinary sphincter (AUS) model AS 800 in patients with urinary incontinence.
• To determine the rates of continence, improvement in urinary control, and complications associated with AS 800 implantation.
• To analyze patient demographics and surgical variations influencing outcomes.

Main Methods:

• Retrospective analysis of 166 patients implanted with the AS 800 artificial urinary sphincter.
• Data collection included patient demographics, etiology of incontinence, implantation site, follow-up duration, and outcomes.
• Complication rates, including mechanical failures, cuff erosions, and infections, were recorded and analyzed.

Main Results:

• Total or near-total continence was achieved in 75.3% of patients (125/166).
• An additional 15.1% (25/166) experienced improved urinary control.
• Reoperation rates were 19.3% (32/166), with mechanical device failure (7.8%) and cuff erosion (6.6%) being the most common complications.

Conclusions:

• The AS 800 artificial urinary sphincter is an effective treatment for urinary incontinence, offering significant continence rates.
• While surgical complications are present, they are manageable and do not negate the overall positive impact on patient quality of life.
• Further research may focus on optimizing surgical techniques and patient selection to minimize complications and maximize outcomes.
