Sorry to be so late in replying, I just read your note.
I started in 2007 with CIS in the bladder. 2 rounds of 6x BCG, 2 rounds of 3x BCG. Last year they found a T1 in the ureter on biopsy.
They insertd a nephrostomy tube to the kidney. This was a bit uncomfortabe as I tend to sleep on that side. The first week ther was a bag attached and I went through the bag. Not much worse than having a catheter with a bag.
After it healed, they did a 6x BCG through the tube. It was no worse than the BCG through a catheter. The infusion took an hour, but you can sit and walk around. A week after the treatment, the nephrostomy tube was removed.
Unfortunately, this treatment did not work, the cancer in the ureter returned and I had to have the kidnay and ureter removed at which point the cancet was T3.
Hope your treatment went better.
