What Is Blood in Urine, Types, Causes, Diagnosis, Treatment

What is blood in urine (hematuria)?

The presence of blood in urine, also known as hematuria, can be a concerning symptom that warrants prompt medical attention.

It is crucial to consult a healthcare professional for a thorough evaluation if you experience blood in your urine. The diagnostic process may involve a medical history review, physical examination, imaging studies (such as ultrasound or CT scans), and urine tests. The underlying cause will determine the appropriate treatment, which may include antibiotics, medications, lifestyle changes, or, in some cases, surgical intervention.

If you notice blood in your urine, it is important not to ignore the symptom. Seek prompt medical attention to determine the cause and receive appropriate care. This information is for general knowledge purposes, and you should always consult with a healthcare professional for personalized advice based on your specific situation.

Types of blood in urine (hematuria)

Hematuria can be categorized into two types:

  • Microscopic hematuria, which is only visible under a microscope.
  • Gross hematuria, which is visible to the naked eye.

1. Blood in urine in females


Here are some potential causes of blood in urine in females:

Urinary Tract Infections (UTIs): Infections in the urinary tract, including the bladder, urethra, and kidneys, can cause irritation and bleeding.

Kidney Stones: The passage of kidney stones through the urinary tract can lead to microscopic or visible blood in the urine.

Bladder or Kidney Infections: Infections in the bladder or kidneys may cause inflammation and bleeding.

Trauma or Injury: Any trauma or injury to the urinary tract, such as a fall or accident, can result in blood in the urine.

Interstitial Cystitis: A chronic condition causing inflammation of the bladder walls, leading to pain and bleeding.

Sexual Activity: Intercourse can sometimes cause minor trauma to the urinary tract, resulting in blood in the urine.

Menstruation: Sometimes, blood from menstruation can mix with urine and cause it to appear red or pink.

Vigorous Exercise: Intense physical activity can lead to muscle breakdown, including in the urinary tract, causing blood in the urine.

Medications: Certain medications, such as blood thinners, can increase the risk of bleeding.

Blood Disorders: Conditions affecting blood clotting or disorders like sickle cell anemia may contribute to blood in the urine.

Cancer: Tumors in the urinary tract, including the bladder, kidneys, or urethra, may cause bleeding.


Medical History: The healthcare provider will ask about the patient’s medical history, including any existing medical conditions, medications, and symptoms.

Physical Examination: A physical examination may be conducted to assess overall health and identify any visible signs of injury or infection.

Urine Analysis: A urine sample will be collected for analysis.

Imaging Studies: Various imaging tests may be ordered to visualize the urinary tract and identify any structural abnormalities.

Cystoscopy: Cystoscopy involves the insertion of a thin, flexible tube with a camera (cystoscope) into the urethra and bladder to visually examine the interior of these structures. This procedure allows the healthcare provider to identify any abnormalities, such as tumors or inflammation.

Blood Tests: Blood tests may be conducted to check for conditions that could be contributing to the hematuria, such as kidney function, blood clotting disorders, or autoimmune diseases.

Biopsy: In some cases, a biopsy of the bladder or kidney tissue may be recommended to evaluate any suspicious lesions or abnormalities identified during imaging or cystoscopy.

Additional Tests: Depending on the findings, additional tests may be necessary to pinpoint the cause of the hematuria. This could include tests for infectious agents or specific markers associated with certain conditions.

2. Blood in urine in males


Urine containing blood has a wide range of potential reasons. Bloody urine may be caused by a problem in your kidneys or other parts of the urinary tract, for example:

  • Bladder or kidney cancer
  • Bladder, kidney, prostate, or urethra infection
  • Inflammation of the kidney (glomerulonephritis), prostate, bladder, or urethra
  • Harm to the kidneys or bladder
  • Stones in the kidneys or bladder
  • Childhood strep throat-related kidney illness (post-streptococcal glomerulonephritis), which frequently results in blood in the urinerenal failure
  • Polycystic kidney disease
  • Renal failure
  • Recent surgery, kidney biopsy, circumcision, catheterization, or other urinary tract operation


  1. Analysing urine
  2. Cytology of urine
  3. Blood tests can identify infections, renal disease symptoms, and other conditions that result in blood in the urine
  4. Kidney stones and other anomalies can be found and the urinary structure can be evaluated with the aid of imaging procedures like CT or ultrasound scans.
  5. Cystoscopy, a day procedure for looking for abnormalities in the bladder lining
  6. Renal biopsy for kidney disease tissue diagnosis

How is blood in urine (hematuria) treated?

Depending on the illness that led to hematuria, treatment can involve the administration of antibiotics to remove a urinary tract infection, a prescription medicine meant to decrease an enlarged prostate, or undergoing shock wave therapy to smash stones in the bladder or kidney. Sometimes no medical intervention is required.

It’s essential to see a healthcare professional promptly if you notice blood in your urine. They will perform a thorough evaluation, which may include a physical examination, medical history review, urine tests, imaging studies (such as ultrasound or CT scan), and possibly a cystoscopy (a procedure to examine the inside of the bladder and urethra).
