Hematuria
Blood in the urine. Hematuria may or may not be accompanied by pain, but it is always abnormal and should be further investigated. Painful hematuria can be caused by a number of disorders, including infections and stones in the urinary tract. Painless hematuria can also be due to many causes, including cancer. See also hematuria, gross; microhematuria.
