Activating an Artificial Urinary Sphincter: Patient Instructions

The artificial urinary sphincter (AUS) — typically AMS 800 — restores continence via a mechanically controlled cuff around the urethra.

Activation/Deactivation Procedure

1. Sit comfortably on toilet or chair.
2. Hold the remote control handpiece (pump) against the scrotum/labia over the implanted pump (in scrotum/labia majora).
3. To void (deactivate): Squeeze and hold the pump for 3–5 seconds → cuff opens → urine flows. Release pump → cuff auto-reinflates in 1–3 minutes (refill delay).
4. To store urine (activate): No action needed; cuff remains inflated (closed) at baseline pressure (61–70 cm H₂O).

Key Points

• Pump location: scrotum (men), labia majora (women).
• Pressure-regulating balloon (abdomen) maintains cuff pressure.
• Typical cycle: 3–4 voids/day; avoid excessive cycling.
• Infection, erosion, mechanical failure → revision surgery.

Patient Education Essentials

• Demonstrate pump location and squeeze technique pre-op.
• Practice with training device.
• Carry device ID card; inform all providers.
• Antibiotics for any invasive procedure.

AUS provides excellent continence (85–90% dry) with learning curve. Most patients master within weeks.
