Blood in Urine

(Hematuria—Adult)
  • Definition

    Blood in the urine is also called hematuria. Normally, urine does not contain blood.
    There are two kinds of hematuria:
    • Microscopic hematuria—Urine contains a small amount of blood, which is not visible to the naked eye
    • Gross hematuria—Urine is visibly discolored by blood, appearing red or tea-colored
  • Causes

    In some cases, the cause of hematuria is never found. The list of known causes is lengthy. Some more common causes include:

  • Symptoms

    In some cases, there may not be additional symptoms.
    But, if you have an underlying condition, you may have other symptoms. For example, kidney stones can cause blood in the urine, along with pain in the side, abdomen, or groin.
    When Should I Call My Doctor?
    Call your doctor any time you notice blood in your urine.
  • Diagnosis

  • Treatment

    Treatment will depend on the cause of hematuria. Some causes of hematuria require no treatment or will resolve on their own. Other causes will respond to medication. For example, treating a urinary tract infection with antibiotics will stop the hematuria. Still, other causes may require surgery, such as the removal of a tumor or treatment for prostate cancer .
  • Prevention

    Treating the underlying condition that causes hematuria may help prevent it from occurring.
