My instructions were for a full bladder to help lift it out of the way... Each treatment, the technicians asked me if my bladder was full. If I had forgot, they said they would have me drink a liter and wait 30 minutes. In asking them their definition of "full", they were actually looking for moderate to full... being able to still be comfortable... :-)
I think I remember that English Alf got instructions that talked about bladder, bowel (empty vs full), and gas! Sounded like it was real complicated and even included dietary constraints. I will ask about that with my oncologist at the next follow up.
I will say that thru and after the treatments, I had no changes in urinary function or urgencies. Only felt a few slight twinges of something when I urinated for 1-3 hours after the treatment. No incontinence factors either... I did get a little rectal proctitis during the last 2 weeks with slight spot bleeding, but it cleared up 2-3 weeks after treatments ended. I never did experience any loose bowels that they talked about... Actually more on the constipated side... but that actually started a few months before treatments when I started taking simvastatin cholestorel medicine.
Waiting now for a few more weeks so I can get my post PSA and get back in the zero club!
Hoping your treatments go well for you with little side effects!
