Diagnosis

These tests and exams play a key role in finding a cause for blood in the urine:

  • Physical exam. This includes a talk with a health care provider about your health history.
  • Urine tests. These can be used to diagnose blood in the urine. They also can be used weeks or months later to see if the urine still has blood in it. Urine tests also can check for a urinary tract infection or for minerals that cause kidney stones.
  • Imaging tests. An imaging test is often needed to find the cause of blood in the urine. You might need a CT or MRI scan, or an ultrasound exam.
  • Cystoscopy. A health care provider threads a narrow tube fitted with a tiny camera into your bladder to check for signs of disease.

Sometimes the cause of blood in the urine can't be found. In that case, you might need regular follow-up tests, mainly if you have risk factors for bladder cancer. These risk factors include smoking, radiation therapy to the pelvis or exposure to certain chemicals.

Treatment

The treatment for blood in the urine depends on the cause. Treatment might involve:

  • Taking antibiotic medicines to clear a urinary tract infection.
  • Trying a prescription medicine to shrink an enlarged prostate.
  • Having a treatment that uses sound waves to break up bladder or kidney stones.

In some cases, no treatment is needed.

If you get treatment, see your provider afterward to make sure there's no more blood in your urine.

Preparing for your appointment

You can start by making an appointment with your regular health care provider. Or you might be referred to a doctor who specializes in urinary tract disorders, called a urologist.

Here's some information to help you prepare for your appointment.

What you can do

Make a list of:

  • Your symptoms. Include any symptoms, even ones that may not seem to be related to the reason for your checkup. Note when your symptoms began too.
  • Key medical information. This includes other conditions for which you're being treated. Note whether bladder or kidney diseases run in your family too.
  • All medicines, vitamins or other supplements you take. Include the doses for each. The dose is how much you take.
  • Questions to ask your health care provider.

Some questions to ask about blood in the urine include:

  • What might be causing my symptoms?
  • What tests do I need?
  • How long might this condition last?
  • What are my treatment choices?
  • I have other health issues. How can I best manage them together?
  • Are there brochures or other printed material that I can have? What websites do you suggest?

Ask any other questions too.

What to expect from your doctor

Your provider is likely to ask you questions, such as:

  • Do you have pain when you pee?
  • Do you see blood in your urine only sometimes or all the time?
  • When do you see blood in your urine — when you start peeing, toward the end of your urine stream or the entire time you're peeing?
  • Are you also passing blood clots when you pee? What size and shape are they?
  • Do you smoke?
  • Are you exposed to chemicals on the job? What kinds?
  • Have you had radiation therapy?
