When you get a prostatectomy they take more than your prostate, they also take two sphincters that men have over women to control our bladder, being left with the same mechanisms that women have. It takes getting used to. When you pee do you have the urge and it's indeed quite a bit or is it less than what you think a full bladder should be? I ask because you could have bladder urgency that doesn't really required you to go pee but you think it does, and you can try waiting those a bit more each day until you get through a night. You can also take Oxybutynin to help with bladder urgency - I was put on that as a precaution but stopped it after a few days past surgery.

For me I notice nothing different, it feels like the same system is still there and while I was usually up 1 time a night to pee, now I'm not.
