I guess I have been fortunate, but I’ve haven’t had any issues on holding the BCG as prescribed. I do not have liquids past 10 PM the day before (I do “swish” bottle water the next day, though) and I eat light the night before (soup). Somewhere I read that having an empty bowel reduces pressure on the bladder.
Do you stay in one position, or roll, or walk?
I did the rotate 1/4 turn each 15 minutes, and can tell you that when it came to laying on my stomach, that really added pressure and I felt like I had to go right away. Near the end of my 6 Induction, I would cut my stomach 15 minutes short, so I could then last the 2 hours easily.
For me, I could stop drinking 2-3 hours before the treatment, and survive 2 hours each time.
The RN does drain your bladder with the catheter prior to inserting BCG? The RN stated to me that this is done because the catheter can clear out more urine from the bladder than our body can.
