BCG is given when all evidence of bladder cancer is gone. This is why a second TURBT should be done to verify this. And any pathology samples should be second opinioned, as well. I am lucky that after both my TURBT's, I did not need to have a catheter (the odds are 50:50). The catheter that was used to install the BCG in my bladder was kept in via an air block, and after two hours, I just unblocked the air, and the catheter readily came out. I used "overnight unisex incontinence underwear "to hold the catheter in place and checked to see that it was sufficiently long to place it into the underwear. No problems at all and it was nice to not worry about any leakage. All these items were "red bagged" and isolated from my other trash. The clothing that I had used was as well isolated and washed separately.

Again, I just use Lysol ( I checked with my pharmacist and was told that this is just as good as "bleach" and not as toxic ) - as a disinfectant for the six hours that the BCG remains "hot". I poured the liquid down the toilet bowl with the cover down and left it in for 15 minutes after each pee out. I used Lysol spray to disinfect the toilet bowl sides afterwards, The six hours are timed from the initial installing. If the BCG is installed at 1:00 PM, it is "live" until 7 PM. It will become routine and this instructing is a good review for me, as I have my first three week BCG maintenance scheduled in mid April.

BCAN is an excellent resource, related to anything concerning Non-invasive HIGH GRADE T1 Bladder Cancer.
So I am glad that you are "tuned in".
