Thank you for your question. Painless discharge of blood in the urine is a cause for concern. The most common cause of painless hematuria (blood in the urine) is the development of bladder cancer. We are not telling you this to alarm you but we want you to promptly go to your doctor to be examined. You may need to undergo an ultrasound, and consult a urologist to rule out the cancer as a cause of your bleeding. It is also possible, on a less serious note, that you may be suffering form a developing urinary tract infection which can simply be treated with a course of antibiotics. Please see your doctor immediately.
