So the laparoscopic? Using the Davinci robot? If so, that's what my dad had done at Toronto General. Much lower risk of losing "male function" going this route, though I know he now needs blue pill "assistance", but at his age, I'm not really surprised about that even without the surgery.
Regaining bladder control will be an adventure. You have to teach your body to use that muscle and it takes considerable time and effort. Be prepared for that, and be prepared to get help with that. I will impact your ability to go places and when you have to go, it comes on insanely fast! I took my dad to his follow-ups and there were some "I have to go, NOW" moments during the trip.
It has been I think 4 or 5 years now and things are normal. His PSA is 0 and he's healthy and cancer free.
Best luck to you!
