Blood In Urine

How can I tell if I have blood in my urine?

There are two types of blood in the urine, visible and microscopic. Some patients see pink or brown after wiping. This could be blood from the urinary tract, genital tract or colon. A urine test will determine if this blood is from the urinary tract. Sometimes a routine urine test from the doctor will detect blood in the urine, where a patient does not see the blood. This is microscopic blood, or hematuria.

What are the causes of blood in the urine?

Urine containing blood can occur for different reasons, and having a comprehensive exam with diagnostic evaluations is required to ensure the most appropriate treatment is provided. Some of the most common causes include: 

• Bladder or kidney cancer

• Kidney or bladder stones

• Urinary tract infections

• Sexually-transmitted diseases

• Polycystic kidney disease

• Kidney failure

• Trauma to the kidneys or bladder

How can a doctor determine where the blood is coming from?

When blood is detected in the urine, several tests can be used to determine the cause. In addition to a urinalysis, blood work may be ordered and diagnostic imaging like CT scan, ultrasound or MRI may be ordered to gain a better picture of the bladder, kidneys, ureters and other organs and structures. Depending on the results of these tests, other exams and evaluations may be performed, including cystoscopy to see inside the bladder or biopsies to take tiny tissue samples of masses viewed on image results. Sometimes, bleeding in the uterus can cause blood to appear in the urine. In that case, a hysteroscopy may be performed to see inside the uterus.

What should I do if my urine looks pinkish or brownish?
