Hematuria


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.
