Artificial urinary sphincters, also also known as inflatable artificial sphincters and urinary control systems, are devices used for treatment of urinary stress incontinence (e.g. due to pelvic floor dysfunction in female or prostate surgery in male) and are sometimes used in combination with a bladder neck stent.
Components
A typical design includes:
- urethral cuff at the bladder neck or proximal urethra
- fluid balloon reservoir (placed usually under the lower abdominal muscle, connected directly with the cuff)
- a pump which relaxes the cuff by moving fluid from the cuff to the balloon (placed under the skin of lower abdomen or leg, or alternatively in the scrotum in male)
- connecting tubes
Function
The pump can be manually used to inflate or deflate the urethral cuff by redistributing the fluid between the cuff and the balloon reservoir. Deflation of the cuff allows urine to leave the bladder and flow through the urethra. The fluid from the balloon is automatically shifted back to the cuff after approximately 2 minutes.
