Bladder Neck Artificial Urinary Sphincter

In less than 5% of people undergoing AUS surgery, the cause of the leakage is not prostate cancer treatment but, rather, neurologic diseases like spinal cord injury or spina bifida.

The bladder neck is the area at the bottom of th bladder where it funnels down from a wide bladder to a narrower urethra.
