What is blood in the urine?

Blood in the urine means there are red blood cells (RBCs) in the urine. Often, the urine looks normal to the naked eye. But when checked under a microscope, it contains a high number of red blood cells. In some cases, the urine is pink, red, or the color of tea, which you can see without a microscope.

What causes blood in the urine?

Most of the causes of blood in the urine are not serious. For example, heavy exercise may cause blood in the urine, which often goes away in a day.

Other, more serious causes include:

Cancer
Kidney infection or disease
Urinary tract infection (UTI)
Enlarged prostate (men only)
Kidney or bladder stones
Certain diseases (like sickle cell anemia and cystic kidney disease)
Injury to the kidneys

Some medications cause blood in the urine. And many people have it without having any other related problems.

What are the symptoms of blood in the urine?

There not be enough blood in the urine to change the color, but in severe cases, the urine may look pink, red, or tea colored.

How is blood in the urine diagnosed?

Your doctor will review your medical history and do a physical exam. Other tests may include:

Urinalysis. Urine is tested for various cells and chemicals, such as red and white blood cells, germs, or too much protein.
Blood tests. Blood is checked for high levels of waste products.

If these tests aren’t clear you may need other tests, such as:

Intravenous pyelogram (IVP). A series of X-rays of the kidney, ureters (the tubes connecting the kidneys and bladder), and bladder is done after a contrast dye is injected into a vein. This is done to look for tumors, kidney stones, or any blockages, and to check blood flow in the kidneys.
Ultrasound. An imaging test that uses high-frequency sound waves to make images of the organs of the urinary tract on a computer screen.
Cystoscopy. A thin, flexible tube and viewing device, is put in through the urethra to examine the parts of the urinary tract for structure changes or blockages, such as tumors or stones.

How is blood in the urine treated?

If you have blood in your urine that lasts more than a day, see a health care provider, especially if you have unexplained weight loss, discomfort with urination, frequent urination, or urgent urination.

Treatment will depend on the cause of the blood in the urine.

Tips to help you get the most from a visit to your health care provider:

Before your visit, write down questions you want answered.
Bring someone with you to help you ask questions and remember what your provider tells you.
At the visit, write down the names of new medicines, treatments, or tests, and any new instructions your provider gives you.
If you have a follow-up appointment, write down the date, time, and purpose for that visit.
Know how you can contact your provider if you have questions.

What is hematuria?

Hematuria means that red blood cells are in the urine. Urine does not normally contain red blood cells. The filters in the kidney prevent blood from entering the urine. When you have hematuria, the filters in the kidneys or other parts of the urinary tract (the kidneys, ureter, and bladder that work together to remove wastes) allow blood to leak into the urine.

There are two types of hematuria:

Microscopic hematuria: Blood can only be seen with a microscope.
Gross hematuria: Urine appears red or the color of tea or cola to the naked eye.

What causes hematuria?

Hematuria is common and can have many different causes.

These causes include:

Inflammation: kidney, urethra, bladder, or prostate (in men)
Abnormal structures in the urinary tract: Kidneys that contain cysts (fluid-filled sacs) or are blocked may lead to any type of hematuria. An ultrasound of the kidney can determine if an abnormal structure is causing blood in the urine.
Inherited diseases: Several different diseases that run in families can cause hematuria. These include polycystic kidney disease, Alport syndrome, inherited nephritis, certain types of hemophilia, and sickle cell disease.
Mineral imbalances in the urine: High levels of calcium in the urine can cause hematuria. The hematuria may be painless or cause pain in the area of the kidney and/or a burning feeling during urination. Those with high levels of calcium in the urine are more likely to have a family member with a history of kidney stones. Individuals that have this condition have a higher risk for having a kidney stone, but less than 10-15 percent develops a stone. Most adults with microscopic hematuria do not need treatment unless they have a kidney stone.
Glomerulonephritis: A common cause of blood in the urine. There are many types of glomerulonephritis. Some of these are mild and resolve on their own while others are more serious and need medication. Blood tests can identify some kinds of glomerulonephritis. In some cases, a kidney biopsy may be needed to find the exact form of the disease.
No cause (idiopathic hematuria): "Idiopathic" means that no specific cause can be found for blood in the urine. Idiopathic hematuria can run in families, and is called familial idiopathic hematuria. When there is not a family history of kidney failure and other medical tests are negative; usually, no treatment is needed.

What are the tests for hematuria? (adsbygoogle = window.adsbygoogle || []).push({});

Adults who have microscopic hematuria with normal blood pressure and kidney function should have their urine checked over several months.

If blood in the urine continues:

A kidney ultrasound may be performed.
Urine should be checked for protein and may be checked for calcium and creatinine (a waste product found in your urine).
Blood test to determine kidney function and other tests may be performed.
If all tests are negative, and blood remains in the urine, yearly checkups should be done.

Adults who have microscopic hematuria with high blood pressure, abnormal blood tests, a family history of kidney disease or high levels of protein in the urine may need to have a kidney biopsy.

How is hematuria treated?

If your hematuria is caused by an infection, like a urinary tract infection (UTI), hematuria is treated with antibiotics. Your healthcare provider will test your urine after treating you with antibiotics to make sure that your infection has cleared. The goal of your healthcare provider is to find the cause of blood in your urine. If no serious condition is causing hematuria, no treatment is needed.

What does hemolyzed trace in urine mean?

Answer. Trace lysed blood refers to a finding that is usually reported from a urinary dip stick analysis. It implies that there is a small quantity of red cells in the urine that have broken open. The developer on the dip stick reacts with the hemoglobin that is released when the red cells are lysed.

What is the most common cause of trace blood in urine?

Urinary tract infections. This is the most common cause of microscopic hematuria.

Why would you have blood in your urine but no infection?

Blood in the urine is a key sign of bladder cancer. It also may be a sign of kidney or prostate cancer. In some cases, you might not have any other symptoms. That's one reason why it's important to let your doctor know when you notice any blood.
