Hi Lynda; Welcome back and congrats on the all clear.
It is normal to have some residual or microscopic blood in the urine after TURBTS, BCGs and even a scope exam. I too, had 21 BCGs and did have some microscopic blood for a while. I was told it was due to inflammation of the bladder lining and urethra. I’ve been clear of blood for a long time now. If it is bothering you I suggest that you discuss with your uro about having a backup urine test to compare to your family doc’s and if he isn’t concerned about the blood still ask for an explanation to put your mind at rest. There may be a valid reason for it in your case but only your doc will be able to tell for sure. Let us know how it goes.
