Hematuria is blood in the urine. There are two types of hematuria. Gross hematuria is when you can see the blood in your urine. Microscopic hematuria is when you can’t see blood in the urine, but it is found with a urine test and seen under a microscope. Most people with microscopic hematuria don’t have symptoms.
There are many causes of hematuria. Some common causes include:
Kidney or bladder stones
Kidney trauma or injury
Urinary tract infection
Certain medications like blood thinners or pain relievers
Other more serious causes may include:
Bladder, kidney or prostate cancer
If you see blood in your urine, tell your doctor. They will want to see you for an exam, where they will review your full health record and have you take a urine test. In some cases, a blood test or ultrasound may also be needed.
Hematuria is treated by getting to the underlying cause. For instance, hematuria caused by a urinary infection is often treated with antibiotics. Hematuria caused by an enlarged prostate may require more tests to determine the best treatment.
