what is wrong if your urine has blood in it
Blood in urine may be a sign of a serious medical disorder so it does require medical investigation and it should not be ignored. The most common causes of hematuria are kidney and bladder stones, trauma to the kidney, bladder, or other parts of the genitourinary tract.
Blood in the urine can be visible to the naked eye as bright red or brown, or can be present microscopically. The presence of blood means that bleeding is occurring somewhere in the genitourinary tract; that is in the kidneys, ureters, the prostate gland, the bladder or the urethra.
