BCG is the recommended course of action in CIS situations. Your concern certainly makes sense. What did your urologist say about the containment issue given the prostatectomy?
I would imagine the leakage of the BCG would be just as big, if not bigger, an issue as containing it in the bladder long enough. You don't want to be getting that stuff on you.
Maybe a condom catheter with a catheter bag during treatment? Interesting question. I'm curious to know what your uro says on this one.
Good luck with the BCG! Hope it works well for you. Sounds like you've had enough damn cancers for three or four people's lifetimes already.
