Hematuria is the medical term for the presence of blood in the urine. It can be either visible to the naked eye (gross hematuria) or only detectable through laboratory tests (microscopic hematuria). Hematuria may indicate an underlying medical condition, some of which can be serious. It is important to seek medical attention if you notice blood in your urine to determine the cause and receive appropriate treatment.
Gross Hematuria: This is when blood in the urine is visible to the naked eye. The urine may appear pink, red, or brown due to the presence of blood. The blood can come from anywhere in the urinary tract, including the kidneys, bladder, ureters, or urethra.
Microscopic Hematuria: In this case, blood can only be detected under a microscope during a urine test. The urine may appear normal, but microscopic blood cells are present. It’s often discovered during routine check-ups or tests for other conditions.
Hematuria can be caused by a variety of conditions. Some of the most common causes include:
Urinary Tract Infection (UTI): UTIs, particularly bladder infections, are a common cause of blood in the urine. Infections in the urinary tract can irritate the bladder lining, causing bleeding. Symptoms may also include a burning sensation during urination, frequent urination, and abdominal discomfort.
Kidney Stones: Kidney stones are hard deposits of minerals and salts that form in the kidneys. When these stones move through the urinary tract, they can cause intense pain and lead to bleeding. The blood may appear in the urine, and you may also experience pain in the back or side.
Bladder or Kidney Infection (Pyelonephritis): Infections in the kidneys or bladder can cause inflammation and bleeding. This type of infection can cause severe pain, fever, and blood in the urine.
Trauma or Injury: Any physical injury to the kidneys, bladder, or urinary tract can lead to blood in the urine. This can result from accidents, sports injuries, or even medical procedures like catheterization or surgery.
Kidney Disease: Certain kidney diseases, such as glomerulonephritis (inflammation of the kidney’s filtering units), can cause blood in the urine. Conditions like diabetic nephropathy or polycystic kidney disease may also lead to hematuria.
Bladder or Kidney Cancer: Blood in the urine can be a symptom of bladder or kidney cancer. The blood is typically painless and may appear intermittently. If you notice persistent blood in the urine without pain or infection symptoms, it’s important to rule out cancer.
Enlarged Prostate (Benign Prostatic Hyperplasia – BPH): In men, an enlarged prostate can cause blood in the urine due to the pressure it places on the urinary tract. This condition is often associated with other symptoms like difficulty urinating or a frequent need to urinate, especially at night.
Medications: Certain medications, such as blood thinners (e.g., warfarin, aspirin), can increase the risk of bleeding and cause blood in the urine. Chemotherapy drugs can also cause damage to the bladder lining, leading to hematuria.
Vigorous Exercise (Exercise-Induced Hematuria): Intense physical activity, especially running or contact sports, can sometimes cause blood to appear in the urine. This is usually harmless and resolves after a period of rest.
Inherited Conditions: Conditions such as sickle cell disease or Alport syndrome (a genetic disorder that affects the kidneys) can cause blood in the urine due to abnormalities in the kidneys’ filtering systems.
The presence of blood in the urine is the primary symptom of hematuria. However, depending on the underlying cause, other symptoms may accompany hematuria, including:
If you experience blood in your urine, your doctor will perform a series of diagnostic tests to determine the cause. These may include:
Medical History and Physical Exam: The doctor will ask about your medical history, medications, lifestyle, and other symptoms. A physical exam will help assess your overall health and check for signs of infection, injury, or other conditions.
Urine Tests: A urine sample will be tested for the presence of red blood cells, bacteria, or other abnormalities. A urine culture may also be performed to detect any underlying infections.
Imaging Tests:
Cystogram or Intravenous Pyelogram (IVP): These imaging techniques help visualize the bladder and kidneys in greater detail, which can be useful in diagnosing certain conditions, such as bladder cancer or kidney disease.
Treatment for hematuria depends on the underlying cause. Some common treatment options include:
Antibiotics: If a urinary tract infection is the cause of hematuria, antibiotics will be prescribed to treat the infection.
Pain Relief: Nonsteroidal anti-inflammatory drugs (NSAIDs) or acetaminophen may be used to relieve pain associated with conditions like kidney stones or bladder infections.
Stone Removal: If kidney stones or bladder stones are the cause of bleeding, treatment options may include:
Surgery for Tumors or Cancer: If blood in the urine is caused by bladder or kidney cancer, surgery, chemotherapy, or radiation therapy may be necessary to remove tumors or treat the cancer.
Medications for Enlarged Prostate (BPH): In men with an enlarged prostate, medications such as alpha-blockers or 5-alpha-reductase inhibitors may help shrink the prostate and reduce symptoms, including hematuria.
Bladder Instillations: For conditions like interstitial cystitis, bladder instillations (medications placed directly into the bladder through a catheter) can help reduce inflammation and prevent further bleeding.
Observation and Monitoring: In cases of exercise-induced hematuria or mild cases with no serious underlying cause, doctors may recommend simply monitoring the condition over time to ensure it resolves on its own.
If you notice blood in your urine, it is important to seek medical attention right away. In many cases, hematuria can indicate an underlying medical condition that needs to be addressed. You should especially seek help if:
While some causes of hematuria are unavoidable, the following lifestyle changes may help reduce the risk:
