How is acute hematuria diagnosed?

Your caregiver will ask you about your signs and symptoms and examine you. He will ask when you first saw a change in the color of your urine. He will ask if you have any medical conditions. He will ask what medicines you are taking. Some medicines can damage your kidneys or increase your risk of bleeding. Ask your caregiver for more information about these and other tests you may need:

  • Blood and urine tests: Your caregiver will check your urine for signs of an infection that could be causing your symptoms. He will check your blood to learn how well your kidneys are working.

  • X-ray of kidneys, ureters, and bladder: This is also called a KUB. Caregivers use these pictures to check for causes of your acute hematuria.

  • Renal ultrasound: This is a test using sound waves to look at your kidneys. Pictures of your kidneys show up on a TV-like screen. A renal ultrasound can show if you have kidney stones, an abscess, or other problems.

  • CT scan:

    • This is also called a CAT scan. An x-ray machine uses a computer to take pictures of your abdomen to look at the organs and blood vessels in your abdomen, and to check for problems and abnormal changes.

    • You may be given dye before the pictures are taken. The dye is usually given in your IV. The dye may help your caregivers see the pictures better. People who are allergic to iodine or shellfish (crab, lobster, or shrimp) may be allergic to some dyes. Tell the caregiver if you are allergic to shellfish, or have other allergies or medical conditions.

How is acute hematuria treated?

Treatment depends on the cause of your acute hematuria. It may go away on without treatment. You may need medicines, such as antibiotics to treat an infection. Other treatments may be needed to treat the cause of your bleeding. Drink clear fluids to help flush the blood from your urinary tract. Follow your caregiver's instructions about how much fluid to drink. Ask your caregiver for more information about the treatment you will need.

When should I follow up with my caregiver?

Your caregiver will tell you how often to come in for follow-up visits. He may refer you to a specialist, such as a urologist or nephrologist. The specialists may do tests or procedures to find more serious problems with your urinary system. Write down your questions so you remember to ask them during your visits.

When should I contact my caregiver?

Contact your caregiver if:

  • You have a fever that gets worse or does not go away with treatment.

  • You cannot keep liquids or medicines down.

  • Your urine gets darker, even after you drink extra liquids.

  • You have questions or concerns about your condition, treatment, or care.

When should I seek immediate help?

Seek help immediately or call 911 if:

  • You have blood in your urine after a new injury, such as a fall.

  • You are urinating very small amounts or not at all.

  • You feel like you cannot empty your bladder.

  • You have severe back or side pain that does not go away with treatment.
