What Is Hematuria (Blood in Urine)? Definition

Blood in the urine is medically known as hematuria. Doctors often further differentiate hematuria into gross hematuria (blood that can be seen in the urine with the naked eye; often the urine is red in color) or microscopic hematuria (blood cells identified on microscopic examination of the urine). Blood in the urine can occur due to many medical conditions and diseases. Blood in the urine may be associated with painful urination, abdominal or pelvic pain, pus in the urine, or other symptoms, depending upon the cause. It is also possible to have blood in the urine that is not associated with pain or other symptoms.
