I completed radiation treatment about 2 years ago and I would not count on the techs pulling you out of the machine because your bladder is not full. Where I was treated once you climb in they are going to proceed regardless of how full your bladder is. The hospitals main concern was moving people thru treatment at $1K per session and there was no way my bladder not being full was going to stop the process. After treatment I had serious bladder issues had to wear a diaper and they put me on Myrbetriq which helped but was very expensive. I have thought of seeing if the cat scan x-rays are still stored somewhere to evaluate if my bladder not bein full contributed to the issues I am having.
I also battled severe lack of energy after Lupron treatment and found my testorone to be 150. I am doing much better after starting TRT and my leakage issues resolved .
I have found that I need to research and understand my treatment because my doctor certainly does not.
