Hi. Dr Rick here. I completed an Internal medicine internship in NYC and have two decades of clinical experience. How can I assist you today?
That is an excellent question and I can assure you that if your doctor thought that he should do the scope right away with this new episode of bleeding he would work late and make sure you were treated right away. He would put off necessary treatment for the sake of his schedule.
Yes, a cysto can be done with blood in your urine as there is a large volume of fluid flushed through your bladder during the procedure so the amount of bleeding you are having would not interfere at all.
If you do not want to wait, and given your history I can't say that I blame you for feeling that way, then I 'd contact another urologist and see if you can be scoped right away.
Clinically, will it make a difference? Probably not. But if I was my bladder bleeding I'd want a scope sooner rather than later too :)
Does this make sense to you?
