Yes, it would have been nice if my urologist had prepared me for possible side effects of having my prostate removed. About 24 hours after coming home from the hospital, my scrotum began to swell. Eventually it more than doubled in size. For a full 24 hours, my scrotum had become so enlarged that I could no longer see the head of my penis. All I could see was the catheter tube poking out of the enlarged scrotum. I was sure something was very wrong, but when I called the urologist office, I was assured this was not unusual; no need to go to the ER. And the scrotum did slowly return to normal size about a week after the operation. Definitely a scary side effect, but not serious. Hope this helps.
