TURB April 2008
Last BCG (#15) April 2009
The urine needs to be checked for blood and/or infection.
Do not use in the presence of a UTI because administration may result in the risk of disseminated BCG infection or in an increased severity of bladder irritation.
My doctor did . But the hospital didn't for my first one. I told my urologist and he called them. so from now on they will do that. He said it is a simple dipstick kind of thing and they were fine with it.
I go for the second one tmorrow
