Diagnosis

The following tests and exams play a key role in finding a cause for blood in your urine:

  • Physical exam, which includes a discussion of your medical history.
  • Urine tests. Even if your bleeding was discovered through urine testing (urinalysis), you're likely to have another test to see if your urine still contains red blood cells. A urinalysis can also check for a urinary tract infection or the presence of minerals that cause kidney stones.
  • Imaging tests. Often, an imaging test is required to find the cause of hematuria. Your doctor might recommend a CT or MRI scan or an ultrasound exam.
  • Cystoscopy. Your doctor threads a narrow tube fitted with a tiny camera into your bladder to examine the bladder and urethra for signs of disease.

Sometimes, the cause of urinary bleeding can't be found. In that case, your doctor might recommend regular follow-up tests, especially if you have risk factors for bladder cancer, such as smoking, exposure to environmental toxins or a history of radiation therapy.
