I'm 5 years after HDR Brachy.
I've had a couple of incidents of bleeding prostate over the last year, and one UTI, but that was carelessness on my part cleaning up the blood.
I work with a few urologists who are always saying radiotherapy causes this and that problem. Well, they only get to see the patients who do have problems and not those who don't, so even though it's small minority, that's all the urologists see, so in their eyes, all radiotherapy patients have problems.
Conversely, the oncologists get to see 30% of the prostatectomy patients, for whom the procedure fails.
