@rockin2047 , I think I was fortunate because the only side effect I experienced during treatment was urgency to urinate, but as I recall it was only during the first couple of weeks of treatment (after that ... no urgency experienced). I experienced no bowel or rectum issues (I had SpaceOAR) and no ED issue. During each weekly consult with my oncologist, he seemed really pleased that I wasn't experiencing other common urinary difficulties (e.g., hesitation, dribbling, weak stream, incomplete bladder emptying), painful urination, or frequency of urinating. In speaking to a few other guys who were being treated during the same timeframe, it seems that their urinary difficulties were successfully treated with Flomax pills. Also, keep in mind that I didn't have SBRT so my experience (lower radiation doses over longer timeframe) may not be a good indicator for you.
