So I won the lottery last September when they found PC in most of my P and a lot of my seminal vesical as well. This eventually led to my choosing to have a radical robotic prostatectomy with non-nerve sparing. The surgery went fine but when the pulled the catheter out after surgery I found (Like most men) that I was incontinent. This is disturbing (I say in that it was horrifying). I knew it was likely and it was still horrifying. Perhaps there are those out there contemplating the same surgery and I have a recommendation.
Before you have surgery, have the surgeon refer you to a good physical therapist experienced in treating incontinence. It's not enough just to "do your kegels". Get a PT to teach you how to do the exercises right. It requires coaching.
I did not do this but I started PT about 6 weeks after surgery and after a few weeks I went from wearing several full diapers a day with maybe 7 or 8 pads to cutting that well in half. It has made a huge difference.
The surgeon is unlikely to recommend PT. You'll have to ask for it. But it helped me immensely and I am going to keep at it.
Good luck brothers and sisters
