Since I am an adjuvant RT guy, I'll try to separate what I know is surgery vs RT.
All nerves taken, so no discussion of pills doing anything more than helping any possible regrowth, but I'm trying. Trimix is my go-to solution for ED.
Incontinence was severe. I am now at two pads a day, was down to one before RT.
Damage to my bladder and urethra from radiation scatter. This manifested itself about
18 months out from the end of RT as periodic clots and blood in urine (December 2011). A cystoscope confirmed damage. It continues today unpredictably, sometime significant, others, just a day or two. I wash a lot of sheets.
Fatigue. It used to be extreme, is less so now, but still brings me to a crash if I don't get an afternoon nap.
Immune system crashed after RT, docs say because so much bone marrow in my hips was exposed. It has not returned, so if someone sneezes, I'm out of there. No movies at a theater, no sporting events, rarely a restaurant. It has killed my international travel job, as I can't be exposed to anything, and can't be vaccinated for a lot of things I would have been exposed to. I carry a bottle of high end antibiotics at all times.
Colo-rectal issues. I had major surgery on my colon & rectum in 2005. The RT caused serious irritation/damage to the already damaged tissue. As a result I have 5-8 BMs per day. My lower colon suffers from the irritated tissue, so ...
Mind you I can break anything, and have a special corollary to Murphy's Law - he was an optimist.
