Here's mu guess. With a prostatic procedure he probably had a catheter inserted. If the catheter tip is pushed into the bladder wall it cannot drain urinary fluid. They did say this admission was for a bladder problem. Just urinary retention, like bloating. You don't go into ICU for that unless you are either crying like a baby or in ICU you get more security.
