That's so true - I've never paid so much attention to my bladder and colon status. Good grief!
I have taken this prep seriously, and had good success with it. As has been noted on our HW forum, it can be disastrous if your bladder is not full! I really feel for Purgatory's problems from that, and so much appreciate his sharing of that warning with all of us embarking on radiotherapy.
With due care, my system has been pretty predictable and fine-tuned to be full bladder/empty rectum every time, for the last 33 treatments. For a couple of weeks before my simulation I experimented with timing to get a full bladder that I could hold for an hour or so. I stop drinking water 2-1/2 hours before appointment time, and I only have to drink 16 oz of water 1 hour before appointment time to have a full bladder at the right time. The kidneys are always filling the bladder at some rate, so the extra 16 oz get me there. I was actually over-full at my simulation, but they said it was ok.
The worst problem has actually been that full bladder business, since there are almost always delays getting in the room. If I'm full at 12:30pm, it gets increasingly uncomfortable to wait until 1:30pm due to their delays. Only once have I had to relieve and reload with water (the machine was balky that day), delaying me about
another hour. No biggie, they just swap a couple people around and get me sequence later. (The actual appointment times are only vaguely related to when one really gets into the room anyway. The technicians work hard, but there's no slack in their schedule so all delays cascade through the day. They're pretty much just taking people in order of appointment time, regardless of the clock.)
Biology and effectiveness reasons aside, frankly the attractiveness to me of SBRT is only having 5 treatments. That sounds awesome right about
now. I have 11 left in my IGRT series as of today.
