I just had my third Radiation shot today after hormones for around 4-5 months.
No major side affects as yet except I think I am going for more urinations at night than usual, but not much more maybe 3-4 times an evening - daytime seems better.
I've been drinking water as suggested - up to 2 litres per day or 24 hrs, but my pre treatment scan showed bladder was reasonable first day, full and great the second day and a bit small the third day. I understand the bladder needs to be full and bowel empty before treatment to clear the prostate.
I do the pre treatment enema an hour before, toileting and then 500ml of water half an hour before. I thought I was drinking enough during the day but it seems to be a bit hit and miss with the bladder. I understand from google the bladder can take 7-8 hours to fill, so having a pee within an hour of your radiation would surely deplete the amount in the bladder??
How are you getting on with this - any issues or has anyone any tips about water intake to ensure your bladder is full before treatment - hope I haven't made it more complicated than it needs to be.
I get this feeling that if the bladder isn't right and full, despite ones best efforts, the Xrays will be hitting it and causing irritation
