After removing the prostate, the surgeon reconnects the bladder to the urethra, and the Foley catheter put in place at the start of surgery is left in place for approximately one week (rarely longer due to possibility of infection). Once the catheter is removed, most men leak urine for a period of time. The leakage occurs mainly due to stress incontinence - failure of the urethral sphincter to close properly (Ficazzola 1998). The sphincter can be thought of like a valve or aperture of a camera; it lies just beyond the prostate.
