WOW! What a story! You are very fortunate that you got to the ER and that they were able to determine a diagnosis.
No, I haven't heard of this happening before (although it no doubt has.) I expect that the team at your urologist's office is having a remedial course in procedures for administering BCG. This is why I always end up drenched with Betadine prior to any catheter insertion.
BCG is such a benefit to so many of us with high grade bladder cancer; it is a real shame to hear something like this.
Hope you are feeling much better.
