Hello, I had Hi-Fu surgery at University of Chicago medicine. Hi-Fu treats the prostate from the outside of the prostate . Tulsa Pro was offered to me about one and a half years later as a new attempt to reach areas missed from the initial Hi-Fu. Tulsa pro enters the prostate and treats it from the inside out. My argument was even the areas treated with Hi-Fu showed up as returning cancer in the PSMA scan that I had done at Northwestern Hospital in Chicago. That is why I questioned the whole Hi-Fu procedures effectiveness. It just didn't work for me. On a case by case it may work for others. I chose it knowing I only had about a 60% chance ( Dr. quote) of success, as it seemed to be the easiest recovery and least invasive. Ultimately had to undergo SBRT for 27-8 visits along with a hated 4 mth ADT shot. Good Luck to you....
