I had Gleason 3+4 as well with a PSA of 10.2. I had no ADT treatment but did have a tight margin, Radiation machine called the Mridian.

After the third dose of the five hypo fractional treatments that I was supposed to have, my urine flow was restricted and they gave me Flomax, which worked overnight. I did have spaceoar put in.

I believe because I had those tight margins for radiation (2 mm vs 3-5 for most other forms of radiation) that the amount of exposure to radiation of my healthy tissue was minimized as were my side effects. I finished treatment in February 2023.
