Artificial Urethral Sphincter (AUS)
The control pump allows you to empty the cuff and allow the urine to come out when you need to pass urine. You squeeze the pump to empty the cuff, and after a minute or so the cuff will automatically refill.
The AUS operation is a bigger procedure than the sling, and manipulating the pump can need a bit of dexterity. Also, because the AUS is a mechanical device with a number of complex components, it may malfunction over time and need replacing. There is a small risk of getting infections around the device, which would mean it may have to be removed and could only be replaced after a few months. There is a small risk of the cuff eroding into the water pipe and causing damage as well. These problems are uncommon, and most patients have a good result from this operation.
However, the AUS is more effective than other treatments for Post Prostatectomy Incontinence, particularly when the degree of leaking is more severe (eg more than 4 pads per day)
