1 Kidney stones, urinary tract infections, kidney disease, blood diseases, and some cancers are all known causes of blood in the urine. 2  Blood in the urine should always be evaluated by a doctor. 3  Blood in the urine may occur on its own or may accompany other symptoms.
No amount of blood in your urine is normal but that doesn't mean that it is caused by something dangerous. Hematuria can be microscopic (not seen except by laboratory studies) or macroscopic (can be seen by the naked eye). The most common reason for blood in the urine is a urinary tract infection or an enlarged prostate. The most worrisome reason for having blood in the urine is cancer of the bladder or kidney. Having smoked in the past, exposure to industrial chemicals, and advanced age can be risk factors for having cancer.
