[|Human|] i have blood in my urine...no pain....blood test showed I MAY have an infection.  Was given strong antibiotic and blood disappeared (visually) within 3 hours.  Had an ultrasound....showed kidney stones (9mm) in one kidney and that the bladder was grossly unremarkable.  2 days later blood seen in urine again for a short period (2 hours)...now I am scheduled for an cystoscopy and wonder what my odds of bladder cancer are?
[|AI|]  Hi, thank you for asking Chat Doctor. I have gone through your query and understood your concerns. Blood in urine can be from anywhere along the urinary tract. Blood at the beginning of urination is most likely to be from urethra, blood towards the end of urination is likely to be from bladder while blood in urine from the beginning to the end is either from the kidney or a severely bleeding lesion in the bladder. This can give you an idea concerning the origin of blood in your urine. With the history of a kidney stone, I think it is most probable that the source of blood would be kidney and not bladder. Even within the bladder, there are other possible causes of blood in urine apart from cancer. I hope that answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. We will be delighted to answer more questions from you. I wish you good health
