Hematuria, Adult

ExitCare Image Hematuria (blood in your urine) can be caused by a bladder infection (cystitis), kidney infection (pyelonephritis), prostate infection (prostatitis), or kidney stone. Infections will usually respond to antibiotics (medications which kill germs), and a kidney stone will usually pass through your urine without further treatment. If you were put on antibiotics, take all the medicine until gone. You may feel better in a few days, but take all of your medicine or the infection may not respond and become more difficult to treat. If antibiotics were not given, an infection did not cause the blood in the urine. A further work up to find out the reason may be needed.


  • Drink lots of fluid, 3 to 4 quarts a day. If you have been diagnosed with an infection, cranberry juice is especially recommended, in addition to large amounts of water.

  • Avoid caffeine, tea, and carbonated beverages, because they tend to irritate the bladder.

  • Avoid alcohol as it may irritate the prostate.

  • Only take over-the-counter or prescription medicines for pain, discomfort, or fever as directed by your caregiver.

  • If you have been diagnosed with a kidney stone follow your caregivers instructions regarding straining your urine to catch the stone.


  • Empty the bladder often. Avoid holding urine for long periods of time.

  • After a bowel movement, women should cleanse front to back. Use each tissue only once.

  • Empty the bladder before and after sexual intercourse if you are a female.

  • Return to your caregiver if you develop back pain, fever, nausea (feeling sick to your stomach), vomiting, or your symptoms (problems) are not better in 3 days. Return sooner if you are getting worse.

If you have been requested to return for further testing make sure to keep your appointments. If an infection is not the cause of blood in your urine, X-rays may be required. Your caregiver will discuss this with you.
