Artificial Urinary Sphincter — AMS 800 (males)
Implantable Device Restoring Urinary Control After Prostate Surgery
What is Artificial Urinary Sphincter — AMS 800 (males)?
The Artificial Urinary Sphincter AMS 800 is the gold-standard surgical treatment for moderate-to-severe male stress urinary incontinence, most commonly occurring after radical prostatectomy or radiation therapy. The device consists of a fluid-filled urethral cuff, a pressure-regulating balloon, and a control pump in the scrotum. By squeezing the scrotal pump, the patient deflates the cuff allowing urination; the cuff automatically re-inflates to maintain continence. The procedure is performed under general or spinal anaesthesia with a hospital stay of 1–2 Days. Success rates reach >85% in appropriately selected patients at experienced centres.
How the Procedure Works
Perineal Incision & Urethra Exposure
A perineal or scrotal midline incision is made depending on the implantation approach; bulbar urethra dissected free.
Cuff Sizing
A urethral cuff sizer is passed around the circumference of the urethra to determine the correct cuff size.
Cuff Placement
The correctly sized cuff is placed around the bulbar urethra with its tab pointing anteriorly.
Balloon & Pump Placement
The pressure-regulating balloon (61–70 cmH₂O) is placed in the retropubic space; scrotal pump positioned in the dependent scrotum.
Connection & Deactivation
All three components connected with kink-resistant tubing using snap connectors; device deactivated for 6 weeks allowing healing.
Outcomes
Who Needs This Treatment?
- →Men with post-radical-prostatectomy urinary incontinence that has not resolved after 12 months of conservative management.
- →Those with post-radiation incontinence who have adequate urethral tissue for cuff placement.
- →Patients with neurogenic bladder neck incompetence (spina bifida, spinal cord injury) causing severe leakage.
- →Men who have had a failed urethral sling (AdVance or Virtue) requiring salvage treatment.
- →Those with severe intrinsic sphincter deficiency not responsive to other treatments.
- →Patients willing to perform the manual pump activation required for voiding.
"The AMS 800 artificial urinary sphincter is transformative for men with severe post-prostatectomy incontinence. In properly selected patients, it restores dignity and quality of life in a way no other treatment can match."
