Yes, about the MRI, the proof was in the pudding regarding malignant findings as they did find a malignancy in the pathology post-surgery. Indeed, something to be said about it. Observed was a growing consensus about pre-biopsy, or targeted biopsies using MRI based on unnecessary complications that may or may not happen, infections, changes in PSA markers, bleeding, etc. I based my decision on that. My URO gave me an Rx for Flowmax after being catheterized- which didn't make sense to deal with side effects of medication to help me pee through a catheter that was placed there to help me pee- the URO agreed. I didn't welcome bypassing the catheter either for more risks of infection. I was on a forum for catheter users, it was invaluable and informative.
You made the best decision for your health and situation; in the end it's how you feel about it that's important. Above that- no cancer! That's got to be a huge relief! Frequent urinating is normal after surgery, and so is incontinence. I kept an 8 liter water bottle by the bed so I could roll over and wiz into that and return quickly to sleep. I bought some liners, but lucked out with incontinence. It stopped. If I'm really full it can squirt with stress flatulence or a really strong cough. Waking up two times a night is pretty damned good, in my opinion.
I don't know you at all, but I am glad for you and it's hopeful to know that other men are having success out there with this struggle and all that goes with it.
