Seeing blood in your urine can be alarming. While blood in urine may sometimes occur due to a minor or temporary condition, it can also be a sign of an underlying urinary tract or kidney problem that requires medical evaluation.
Blood in urine is medically known as hematuria. It can appear as pink, red or dark-coloured urine, or blood may only be detected through a urine test even when the urine looks normal.
If you notice blood in your urine, you may have questions about what causes it, whether it is serious, what tests may be needed and when you should see a urologist.
This guide explains what blood in urine means, its common causes, symptoms to watch for, how it is diagnosed and what treatment options may be considered.
What Is Blood in Urine?
Blood in urine, or hematuria, means that red blood cells are present in the urine.
It can be classified into two main types:
1. Visible Hematuria
In visible hematuria, blood can be seen in the urine. The urine may appear:
- Pink
- Red
- Brown or cola-coloured
Even a small amount of blood can sometimes change the colour of urine.
2. Microscopic Hematuria
In microscopic hematuria, the urine looks normal but red blood cells are detected during a urine examination.
Microscopic blood in urine may be discovered during a routine health check or while investigating another urinary complaint.
Blood in urine is not a disease by itself. It is a symptom that can have several possible causes. Your doctor will determine the underlying cause based on your symptoms, medical history and appropriate investigations.
What Causes Blood in Urine?
There are several possible causes of hematuria. Some are relatively common, while others may require more detailed evaluation.
1. Urinary Tract Infection (UTI)
A urinary tract infection can cause inflammation and irritation of the urinary tract, which may result in blood in the urine.
Other symptoms may include:
- Burning or pain while urinating
- Frequent urge to urinate
- Passing small amounts of urine frequently
- Lower abdominal discomfort
- Foul-smelling urine
- Fever in some cases
Your doctor may recommend a urine test to determine whether an infection is present.
2. Kidney or Urinary Stones
Kidney stones or stones elsewhere in the urinary tract can cause bleeding when they irritate the urinary tract lining.
Blood in urine may occur along with:
- Severe pain in the side or back
- Pain that radiates toward the abdomen or groin
- Nausea or vomiting
- Pain while urinating
The type and size of the stone and its location help determine the appropriate treatment.
3. Enlarged Prostate
In men, an enlarged prostate, also known as benign prostatic hyperplasia (BPH), may sometimes be associated with blood in the urine.
An enlarged prostate can also cause urinary symptoms such as:
- Difficulty starting urination
- Weak urine flow
- Frequent urination
- Increased nighttime urination
- A feeling of incomplete bladder emptying
A urologist can evaluate these symptoms and determine whether prostate enlargement or another condition is responsible.
4. Kidney Conditions
Certain kidney conditions can cause blood to appear in the urine.
The source of bleeding may sometimes be associated with the kidney’s filtering structures. Additional symptoms or abnormal findings on urine and blood tests may help doctors identify whether the kidneys require further evaluation.
5. Injury or Trauma
An injury to the kidneys, bladder or other parts of the urinary system can sometimes cause blood in the urine.
If hematuria occurs after significant trauma, medical evaluation is important to determine whether there is an injury to the urinary tract.
6. Certain Medicines
Some medications may increase the likelihood of bleeding or may be associated with blood appearing in the urine.
If you notice blood in your urine while taking medication, inform your doctor. Do not stop prescribed medication on your own without medical advice.
7. Urinary Tract Tumours or Cancer
Blood in the urine can sometimes be associated with cancers of the urinary system, including the bladder, kidney or other urinary structures.
Importantly, blood in urine does not automatically mean cancer. There are many other possible causes.
However, unexplained or persistent blood in the urine should not be ignored, particularly when there are no obvious symptoms of infection or another known cause.
Your urologist may recommend appropriate investigations based on your age, symptoms, risk factors and medical history.
What Are the Symptoms Associated With Blood in Urine?
The appearance of blood in urine may be the only symptom in some people.
Depending on the underlying cause, you may also experience:
- Burning or pain while urinating
- Frequent urination
- Urgency to urinate
- Difficulty passing urine
- Pain in the lower abdomen
- Pain in the back or side
- Fever or chills
- Blood clots in the urine
- Weak urine stream
- Unexplained urinary changes
The combination of symptoms can help your doctor determine which part of the urinary system may require further evaluation.
Is Blood in Urine Always Serious?
Not necessarily.
Blood in urine can occur due to conditions such as urinary tract infections, kidney stones, prostate-related problems or other causes.
However, visible blood in urine should not be ignored, even if it occurs only once or disappears on its own.
Some important urinary conditions may initially cause little or no pain. This is why unexplained hematuria may require evaluation by a doctor or urologist.
The seriousness depends on the underlying cause rather than the amount of blood that is visible.
How Is Blood in Urine Diagnosed?
Your doctor will first discuss your symptoms and medical history and may perform a physical examination.
Depending on the situation, investigations may include:
1. Urine Test
A urine examination can help detect:
- Red blood cells
- Signs of infection
- Protein
- Other abnormalities
A urine culture may also be recommended if a urinary infection is suspected.
2. Blood Tests
Blood tests may be used to assess kidney function and look for other abnormalities depending on the clinical situation.
3. Ultrasound
An ultrasound may help evaluate the kidneys and urinary tract and can be useful when looking for certain structural abnormalities or stones.
4. CT Scan
In selected cases, your doctor may recommend a CT scan to obtain more detailed images of the kidneys, ureters or bladder.
The type of CT scan required depends on what your doctor is trying to investigate.
5. Cystoscopy
Cystoscopy involves using a thin instrument with a camera to examine the inside of the bladder and urethra.
It may be recommended when your doctor needs to investigate the lower urinary tract for a possible source of bleeding.
The investigations required vary from person to person. Your urologist will decide which tests are appropriate based on your symptoms and risk factors.
What Is the Treatment for Blood in Urine?
There is no single treatment for hematuria because treatment depends on its underlying cause.
For example:
- Urinary tract infection: Antibiotics may be prescribed when a bacterial infection is confirmed or considered likely.
- Kidney stones: Treatment depends on the stone’s size, location and symptoms. Options may include observation, medication or procedures to remove or break the stone.
- Enlarged prostate: Medicines or procedures may be considered depending on the severity of symptoms and prostate-related findings.
- Kidney conditions: Treatment depends on the specific kidney disorder.
- Other urinary conditions: Additional treatment may be recommended based on the cause identified during evaluation.
The goal is to identify and treat the underlying condition rather than simply treating the blood in the urine.
When Should You Consult a Urologist?
You should consider consulting a urologist if you notice:
- Visible blood in your urine
- Blood clots in the urine
- Repeated episodes of blood in urine
- Blood in urine without an obvious cause
- Burning or pain while urinating
- Persistent urinary symptoms
- Severe pain in the side or back
- Difficulty passing urine
- Blood in urine accompanied by fever
- Abnormal findings on a urine test
Do not wait for the blood to disappear before seeking medical advice. A urologist can determine whether further evaluation is required.
