Artificial Urinary Sphincter

What is an Artificial Urinary Sphincter (AUS)?

An Artificial Urinary Sphincter (AUS) is a surgically implanted device designed to treat severe urinary incontinence, especially in men who have undergone prostate surgery (e.g., radical prostatectomy). It mimics the function of a natural sphincter, providing control over urination.

Who Needs an Artificial Urinary Sphincter?

• Men with severe stress urinary incontinence (SUI) after prostatectomy.
• Patients with neurogenic bladder dysfunction due to spinal cord injury or neurological disorders.
• Individuals who have failed other incontinence treatments (e.g., medications, pelvic floor therapy).

How Does an AUS Work?

The device consists of three main components:

1. Cuff – Placed around the urethra, it closes to prevent urine leakage.
2. Pump – Implanted in the scrotum, allowing manual control of urination.
3. Balloon (Pressure-Regulating Reservoir) – Maintains cuff pressure and regulates function.

Benefits of Artificial Urinary Sphincter (AUS)

✔ High success rate (70–90% improvement in continence).

✔ Long-term effectiveness (can last 10+ years with proper care).

✔ Improved quality of life by restoring bladder control.

✔ Minimally invasive surgical implantation with low complication rates.

Procedure and Recovery

• Surgery Duration: 1–2 hours under general or spinal anesthesia.
• Hospital Stay: Outpatient or short hospital stay (1 day).
• Recovery Time: 4–6 weeks for healing before activation.
• Post-Surgical Care: Avoid heavy lifting, cycling, or pressure on the device.

Risks and Complications

• Device malfunction or erosion (may require revision surgery).
• Infections (rare but possible).
• Urethral atrophy due to prolonged pressure from the cuff.

Is an AUS Right for You?

Men suffering from severe urinary incontinence after prostate surgery may benefit from an AUS, especially if other treatments have failed.
