Artificial urethral sphincter
Artificial urinary sphincters replace the function of the natural urinary sphincter in patients with sphincter damage or neurologic disease, most commonly as a result surgery for prostate cancer.
They are sometimes used in combination with a bladder neck stent.
A typical design includes:
- urethral cuff at the bladder neck or proximal urethra
- fluid balloon reservoir
- connecting tubes
Pump can be manually used to inflate or deflate the urethral cuff by redistributing the fluid in the balloon reservoir. Deflation of the cuff allows urine to leave the bladder and flow through the urethra.
