Bruce - yes , I have been there . Its a huge shock when you hear these diagnosis words ! How old are you ? Your PSA and Gleason are not "off the scale" and actually your PSA is quite low to many pre treatment . Get that PSMA and let us know what it says . You should be able to get a good bounce off of a 4.1 PSA . I had the operation about 4 years ago in April 2021 . Healing takes some time 3-4 months , but after that I was fine . No incontinance , no pain, ED was fine after the first 6 months . I was 58 when I had it , now 62 . I would do it the same way again. God Bless and let us know how the Pet scan works . You may want to ask for a MRI WITH contrast too ! Very effective at time looking at soft tissues in prostate and seminal vesicles . James on Vancouver Island .
