Blood in the urine is a condition known as hematuria. While hematuria is not always visible to the naked eye, it is a sign that there is a potentially dangerous underlying condition that should be treated. Problems with the bladder, prostate, kidneys, ureters, and urethra can all cause hematuria.

Types of Hematuria
Hematuria can be either microscopic or gross. Microscopic hematuria can only be seen with a microscope. Many people do not know they have this condition until they visit the doctor for some other symptom and their urine is analyzed. Gross hematuria is visible to the naked eye, and it causes the urine to look pink, red, or brown.

Around 10% of all people will experience hematuria at some time. Of course, because microscopic hematuria cannot be seen by the naked eye, the incidence may be higher because some people are unaware that they have the condition.

Visible blood in the urine is the most common symptom of hematuria. However, microscopic hematuria also has symptoms. These include fever, abdominal pain, urinary problems, and pain in the side. Symptoms do not have to be present for a patient to have hematuria.

Diagnosis and Treatment
Tests for diagnosis will include urine tests, cytoscopy, and intravenous pyelogram. The goal is to determine what is causing the blood in the urine. Treatment for hematuria will target the cause. Potential treatments include HIFU, x-ray treatment, dialysis, medication, and even possible surgery.
