I just got home from 36 hour HDR brachy implant treatment in the hospital/treatment center. I had 19 needles implanted and was given three treatments total. Not particularly fun lying flat all that time, but they rolled me side to side to keep me relatively comfortable. The dose with this type of brachy is very high, especially to the general prostate/tumor area. (I believe my total Gys a little over 90, about half from the HDR.) Some of the needles were actually placed a little outside the prostate to get treatment to the most likely areas that the cancer might have leaked out. The radioactive wire didn't stop that long in these locations. This HDR treatment followed 26 IMRT treatments. The IMRT shrank the prostate from 46cc to about 35cc size. My known tumor was high at the right base, right up against the bladder. Seeds were not a good choice for me due the the GL7 and the location of cancer. They put a scope inside my bladder while the needles were inserted, as they need to press right up againt the bladder wall, but not penetrate it. The scope showed no sign of cancer into the bladder.
Today I feel pretty good. Not too sore and can't even see where most of the needles went through. Everything seems to be working, but I haven't really tried for an erection - tho a little stimulation in the shower today indicated things should work when I give it a real try. Urine flow is still slow, I'm using Flomax.
I feel this was the right choice for me under my circumstances. I'm in the Central Washington State area. Dr. Sean Cleary at NorthStar Lodge/Memorial Hospital directed my treatments along with my urologist, Dr. Mark Uhlman. Neither really pushed any specific treatment. This one was at the bottom of my list when I first heard of it, but gradually moved up to the top as I researched and understood more about my PCa.
Good luck with your treatment. At this point, I'm feeling pretty good about mine.
