Understanding Haematuria
(Blood in the Urine)
Welcome to our comprehensive guide on haematuria, a condition characterized by the presence of blood in the urine. Discovering blood in your urine can be alarming, but understanding the potential causes, diagnostic procedures, and treatment options can help alleviate concerns and guide you toward appropriate care.
What Is Haematuria?
Blood in the urine, medically known as haematuria, is a condition that requires medical evaluation regardless of how mild or infrequent it may appear. While many cases turn out to be from benign causes, the presence of blood in urine – whether visible to the naked eye (gross haematuria) or only detectable under a microscope (microscopic haematuria) – should never be ignored. Even if the blood disappears on its own or occurs just once, it’s essential to consult your healthcare provider promptly for proper evaluation. This symptom can be the first sign of various underlying conditions, ranging from easily treatable issues to more serious conditions that require immediate medical attention.
Haematuria refers to the presence of red blood cells in the urine. It can be classified into two types:
- Gross Haematuria : Visible blood in the urine, turning it pink, red, or cola-colored.
- Microscopic Haematuria: Blood is not visible to the naked eye but is detected under a microscope during a urine test.
Potential Causes of Haematuria
Haematuria can result from a variety of factors, ranging from benign to serious conditions. Common causes include:
1. Urinary Tract Infections (UTIs)
Bacteria enter the urinary tract, causing infection and inflammation.
– Symptoms: Burning sensation during urination, frequent urge to urinate, cloudy urine.
2. Kidney Infections (Pyelonephritis)
A severe type of UTI that reaches the kidneys.
– Symptoms: Back pain, fever, nausea, and vomiting.
3. Bladder or Kidney Stones
Minerals crystallize in the urinary tract, forming stones that can cause irritation.
– Symptoms: Severe abdominal or back pain, frequent urination, pain during urination.
4. Enlarged Prostate (Benign Prostatic Hyperplasia)
Common in older men; the prostate gland enlarges and compresses the urethra.
– Symptoms: Difficulty starting urination, weak urine stream, urgency to urinate.
5. Kidney Diseases
Conditions like glomerulonephritis affect the filtering units of the kidneys.
– Symptoms: Swelling (edema), high blood pressure, fatigue.
6. Cancer
Bladder, kidney, or prostate cancer can cause haematuria.
– Symptoms: Often asymptomatic in early stages; later stages may include weight loss, pain.
7. Inherited Disorders
Diseases like sickle cell anemia or Alport syndrome.
– Symptoms: Vary depending on the specific disorder.
8. Medications
Certain drugs like blood thinners, aspirin, and some antibiotics.
– Action: May cause urinary bleeding as a side effect.
9. Strenuous Exercise
Intense physical activity can lead to temporary haematuria.
– Symptoms: typically follows very intense physical effort; bright red urine with no other associated symptoms
10. Trauma
Injury to the kidneys or urinary tract from accidents or medical procedures.
When to Seek Medical Attention
If you notice blood in your urine—whether it’s visible or detected through testing—it’s important to consult a healthcare professional promptly. Early evaluation can help identify the cause and initiate appropriate treatment.
Remember: Blood in the urine requires always medical attention!
Diagnostic Procedures
To determine the underlying cause of haematuria, your doctor may recommend:
1. Medical History and Physical Examination
– Discussing symptoms, lifestyle, and medical history.
– Physical checks for abdominal tenderness or masses.
2. Urinalysis
– Laboratory analysis of urine sample to detect red blood cells, infection, or abnormal cells.
3. Blood Tests
– Assess kidney function and check for signs of systemic diseases.
4. Imaging Tests
– Ultrasound: Non-invasive imaging to visualize kidneys and bladder.
– CT Scan: Detailed cross-sectional images to detect stones, tumors, or other abnormalities.
– MRI: Used in certain cases for detailed imaging.
5. Cystoscopy
– A thin, flexible tube with a camera is inserted into the urethra to examine the bladder lining.
Treatment Options
Treatment depends on the identified cause:
Infections (UTIs and Kidney Infections)
– Antibiotics: Prescribed to eliminate bacterial infections.
– Follow-up Tests: To ensure the infection has cleared.
Stones
– Medication: To manage pain and facilitate stone passage.
– Procedures: Lithotripsy to break up stones; surgical removal if necessary.
Enlarged Prostate
– Medications: To shrink the prostate or relax bladder muscles.
– Surgery: In severe cases to remove part of the prostate.
Kidney Diseases
– Medication: To control blood pressure and reduce inflammation.
– Lifestyle Changes: Dietary adjustments and monitoring kidney function.
Cancer
– Treatment Plans: May include surgery, chemotherapy, radiation therapy, or immunotherapy, depending on the stage and type.
Medication Adjustment
– Review Medications: Doctor may adjust dosages or switch medications causing haematuria.
Addressing Trauma
– Medical Intervention: Depending on the severity, may require surgery or observation.
Prevention Strategies
While not all causes are preventable, you can reduce your risk by:
Staying Hydrated
– Drink adequate water to dilute urine and flush the urinary tract.
Practicing Good Hygiene
– Proper genital hygiene can prevent infections.
Avoiding Risk Factors
– Limit exposure to chemicals or radiation that may increase cancer risk. Quit smoking as cigarette smoke is a strong risk factor.
Managing Medications
– Use medications responsibly and under medical supervision.
Regular Check-ups
– Routine health screenings, especially if you have risk factors like a family history of kidney disease.
Frequently Asked Questions
Not always. While haematuria can be a sign of a serious condition, it can also result from minor issues like a mild infection or intense exercise. However, it’s important to have any instance of haematuria evaluated by a healthcare professional.
Dehydration itself doesn’t typically cause blood in the urine but can contribute to kidney stone formation, which may lead to haematuria.
If you notice blood in your urine after strenuous exercise, consult a doctor. They may recommend modifying your exercise routine or investigating other potential causes.
Yes, certain foods like beets, berries, and rhubarb can tint urine pink or red. However, it’s important to distinguish this from actual blood in the urine through medical testing.
I am afraid there is not such a thing as an alternative to cystoscopy that is able to visualise small masses (especially small bladder cancers). As much as this may feel an excess of effort, every patient more than 45 with unexplained haematuria will need a cystoscopy to rule out malignancy in the bladder. In selected cases oa patients younger than 45 years, this may be skipped.
Next Steps
If you’re experiencing haematuria:
Schedule an Appointment: Contact your healthcare provider for evaluation.
Prepare for Your Visit: Note any other symptoms, medications, and personal health history.
Follow Medical Advice: Adhere to recommended tests and treatments.

Remember: Early detection and treatment of the underlying cause of haematuria can significantly improve outcomes. Don’t hesitate to seek medical attention if you have concerns about blood in your urine.
