I am 92 years old now and had IMRT radiation to my prostate a few months ago. During treatment and shortly afterwards I had more frequent urination and bowel movements. Some small incontinence when I go up at night to go to the bathroom. Wetted my pajamas on the way to the toilet. Now there are no side effects. I had been on ADT (Eligard and the Zoladex) for 20 months prior to the radiation and will continue for 2 to 3 years after because my Gleason score was 4+4 = 8, considered high risk. PSA prior to ADT was 14.1, immediately prior to the radiation it was 0.944. The PSA at 5 months after radiation is 0.037. All the literature I have read says that a PSA value like that means a low chance of recurrence in the near future. Basically the radiation of 28 sessions did not cause any fatigue, and I was able to continue life as normal including gym sessions right after radiation 3 days a week.
