Blood in Urine: What Tests Can a Seoul Urologist Perform?

Mijan Mijan • August 18, 2026

Introduction

Seeing blood in the urine can be alarming. The medical term is hematuria, and it can range from microscopic blood that is only detected on testing to visible urine that appears pink, red, or brown.

Blood in urine does not always mean a serious disease. Urinary tract infections, kidney stones, prostate conditions, strenuous exercise, medications, and other issues can cause hematuria. However, visible blood in the urine should not simply be ignored, particularly when it is unexplained, recurrent, or occurs without pain.

For men in Seoul, a urologist can evaluate the possible source of bleeding and determine which tests are appropriate. The diagnostic process may include urine testing, blood tests, ultrasound, CT imaging, cystoscopy, prostate evaluation, or other investigations depending on the patient's age, symptoms, and risk factors.

What Is Blood in the Urine?

Hematuria Can Be Visible or Microscopic

There are two main forms:

Gross hematuria: Blood is visible in the urine.
Microscopic hematuria: Blood is detected through urine testing but cannot be seen with the naked eye.

Both forms may require evaluation depending on the circumstances.

What Color Can Blood Make Urine?

Urine May Look Different Depending on the Amount of Blood

Blood-containing urine may appear:

Pink
Bright red
Dark red
Brown
Tea-colored

Urine color alone cannot determine the cause.

Some foods, medications, and dehydration can also change urine color, which is why laboratory testing can be useful.

Is Blood in Urine Always Serious?

There Are Many Possible Causes

Possible causes include:

Urinary tract infection
Kidney stones
Bladder inflammation
Kidney disease
Prostate conditions
Urethral problems
Trauma
Certain medications
Vigorous exercise
Urinary tract tumors

The likelihood of different causes varies according to age, symptoms, medical history, and other risk factors.

Should Men See a Urologist for Blood in Urine?

Visible Blood Should Generally Be Medically Evaluated

A urology consultation is particularly important when blood in urine:

Appears without an obvious explanation
Happens repeatedly
Occurs without pain
Is accompanied by urinary symptoms
Occurs with weight loss or unexplained fatigue
Occurs with flank or abdominal pain
Occurs in an older man
Is associated with a history of smoking or other urinary-tract risk factors

Can a UTI Cause Blood in Urine?

Urinary Infection Can Irritate the Urinary Tract

A urinary tract infection may cause:

Burning urination
Frequent urination
Urgency
Lower abdominal discomfort
Cloudy urine
Blood in urine

Urinalysis and urine culture can help determine whether infection is present.

Can Kidney Stones Cause Blood in Urine?

Stones Can Irritate the Urinary Tract

Kidney or ureteral stones can cause hematuria.

Possible symptoms include:

Severe flank pain
Pain radiating toward the groin
Nausea
Vomiting
Urinary discomfort
Blood in urine

Imaging may be recommended when a stone is suspected.

Can an Enlarged Prostate Cause Blood in Urine?

Benign Prostate Enlargement Can Sometimes Be Associated With Hematuria

Benign prostatic hyperplasia, or BPH, can cause urinary symptoms such as:

Weak urine stream
Difficulty starting
Frequent urination
Urgency
Nighttime urination

In some men, prostate-related bleeding can also contribute to blood in urine.

However, visible blood should not automatically be attributed to BPH without appropriate evaluation.

Can Prostatitis Cause Blood in Urine?

Inflammation May Produce Urinary Symptoms

Prostatitis can cause:

Pelvic pain
Burning urination
Urinary frequency
Difficulty urinating
Blood in urine in some cases

A urologist may use urine testing and other evaluations to investigate the cause.

Can Exercise Cause Blood in Urine?

Intense Exercise Can Sometimes Produce Temporary Hematuria

Strenuous exercise may occasionally be associated with blood in the urine.

However, persistent or recurrent hematuria should still be evaluated rather than automatically attributed to exercise.

What Is the First Test for Blood in Urine?

Urinalysis Is Usually an Important Starting Point

A urine test can help identify:

Red blood cells
White blood cells
Protein
Signs of infection
Other abnormalities

The results can help determine what additional testing may be appropriate.

What Is a Urine Microscopy Test?

Microscopy Can Examine Blood Cells and Other Urinary Findings

Urine microscopy can provide more detailed information about what is present in the urine.

The shape and characteristics of red blood cells can sometimes help doctors determine whether bleeding may be coming from the kidneys or elsewhere in the urinary tract.

Is a Urine Culture Necessary?

Culture Can Help Identify Bacterial Infection

When infection is suspected, a urine culture can determine whether certain bacteria are present.

This can help guide treatment when a bacterial urinary infection is confirmed.

Can STI Testing Be Needed?

Some Sexual Infections Can Produce Urinary Symptoms

Depending on the patient's history and symptoms, a doctor may consider STI testing.

This may be particularly relevant when blood in urine occurs with:

Burning urination
Penile discharge
Urethral irritation
Genital symptoms
Recent sexual exposure

What Blood Tests May Be Performed?

Blood Testing Can Assess General Health and Kidney Function

Depending on the situation, a urologist may order blood tests to evaluate:

Kidney function
Blood counts
Signs of infection
General health
Other conditions relevant to the symptoms

Blood tests do not identify every cause of hematuria by themselves.

Can PSA Be Tested When a Man Has Blood in Urine?

PSA May Be Considered When Prostate Evaluation Is Appropriate

PSA is a prostate-specific antigen test used primarily in prostate evaluation and prostate-cancer risk assessment.

It is not a direct test for hematuria.

A urologist may consider PSA depending on age, prostate symptoms, examination findings, and individual risk factors.

Can Ultrasound Find the Cause of Blood in Urine?

Ultrasound Provides a Non-Invasive Look at the Urinary System

A urologist may use ultrasound to examine:

Kidneys
Bladder
Prostate
Residual urine

Ultrasound may help identify stones, urinary retention, prostate enlargement, or certain structural abnormalities.

However, a normal ultrasound does not rule out every possible cause of hematuria.

When Is CT Used for Hematuria?

CT Can Provide More Detailed Imaging

A CT scan may be recommended when a doctor needs more detailed information about:

Kidney stones
Kidneys
Ureters
Urinary tract abnormalities
Other abdominal or pelvic conditions

The specific type of CT depends on the suspected diagnosis.

What Is a CT Urogram?

It Provides Detailed Imaging of the Urinary Tract

A CT urogram can evaluate the kidneys, ureters, and bladder using specialized imaging techniques.

It may be considered in selected patients with hematuria when detailed evaluation of the urinary tract is appropriate.

What Is Cystoscopy?

Cystoscopy Allows the Doctor to Look Inside the Bladder

During cystoscopy, a thin instrument with a camera is passed through the urethra to examine the bladder and urethral lining.

It can help identify abnormalities such as:

Bladder tumors
Inflammation
Stones
Urethral abnormalities
Other sources of bleeding

Not every patient with blood in urine needs cystoscopy.

Is Cystoscopy Painful?

The Experience Varies Between Patients

Cystoscopy can cause temporary discomfort, particularly during insertion and urination afterward.

Local anesthetic may be used for certain procedures.

Your urologist should explain what type of cystoscopy is planned and what to expect.

Can a Urologist Check the Prostate?

Prostate Evaluation May Be Appropriate for Men With Urinary Symptoms

Depending on the patient's age and symptoms, the doctor may assess:

Prostate size
Urinary flow
Prostate-related symptoms
PSA when appropriate

Prostate evaluation can help determine whether BPH or another prostate condition may be contributing to urinary problems.

What Is Uroflowmetry?

It Measures How Urine Flows

Uroflowmetry is a non-invasive test that measures:

Urine flow rate
Flow pattern
Approximate voided volume

It may be useful for men with blood in urine who also experience:

Weak urine flow
Hesitancy
Difficulty starting
Incomplete emptying

What Is a Post-Void Residual Test?

It Measures Urine Remaining After Urination

A bladder ultrasound can measure how much urine remains after you finish urinating.

A high residual volume may indicate:

Bladder-emptying problems
Prostate-related obstruction
Other urinary dysfunction

Can Kidney Disease Cause Blood in Urine?

Some Kidney Conditions Produce Microscopic Hematuria

Blood in urine can sometimes originate from the kidneys rather than the lower urinary tract.

If urine testing shows blood together with significant protein or other kidney-related abnormalities, additional evaluation may be appropriate.

In some cases, a nephrologist rather than a urologist may also be involved.

Can Blood in Urine Mean Bladder Cancer?

Unexplained Hematuria Can Require Bladder Evaluation

Bladder cancer is one possible cause of blood in urine, particularly in older adults and people with certain risk factors.

However, blood in urine has many other causes.

The purpose of evaluation is to identify the source rather than assume that cancer is responsible.

Does Painless Blood in Urine Need Evaluation?

Painless Hematuria Should Not Be Automatically Dismissed

Blood in urine without pain can occur with several conditions.

Because some important urinary tract conditions can produce painless hematuria, unexplained visible blood should be discussed with a healthcare professional.

Does Painful Blood in Urine Mean a Kidney Stone?

Pain Can Provide Clues but Does Not Establish the Diagnosis

Severe flank or groin pain with hematuria may suggest a kidney stone.

However, infection and other conditions can also produce pain and blood in urine.

Imaging may be needed to determine the cause.

What Happens During a Seoul Urology Consultation?

The Doctor Will First Review Your Symptoms and Medical History

You may be asked about:

When the blood first appeared
Whether it is visible
Whether it occurs throughout urination
Whether you have pain
Urinary frequency
Burning
Weak urine flow
Previous urinary infections
Kidney stones
Smoking history
Medications
Recent exercise
Previous urological procedures

Does the Timing of Blood During Urination Matter?

The Pattern Can Provide Diagnostic Clues

Doctors may ask whether blood appears:

At the beginning of urination
At the end
Throughout the entire urine stream

This information may help determine which part of the urinary tract should be investigated.

Can Medications Cause Blood in Urine?

Some Medicines Can Increase Bleeding Risk

Certain medications can make bleeding more likely or more noticeable.

Tell your doctor about:

Prescription medications
Blood thinners
Aspirin
Supplements
Herbal products

Do not stop prescribed medication without medical advice.

Can Dehydration Cause Blood in Urine?

Dehydration Can Affect Urine Concentration but Should Not Be Assumed to Explain Hematuria

Dark urine caused by dehydration is not necessarily blood.

If you see red, pink, or brown urine and are unsure whether it contains blood, a urine test can clarify the situation.

Conclusion

Blood in urine can have many causes, ranging from urinary infections and kidney stones to prostate conditions, kidney disease, and other urinary-tract problems. It can be visible or detectable only through laboratory testing.

A Seoul urologist may begin with urinalysis and medical history before recommending additional tests such as urine culture, blood tests, ultrasound, CT imaging, cystoscopy, prostate evaluation, or uroflowmetry.

Not everyone with hematuria needs every test. The appropriate workup depends on age, symptoms, medical history, risk factors, and whether the bleeding is persistent or recurrent.

Foreign residents and international visitors can seek urological evaluation in Seoul and should confirm self-pay policies, language support, available diagnostic services, and expected costs before their appointment.

Unexplained visible blood in the urine should not be ignored, even when there is no pain. Prompt evaluation can help identify the cause and determine whether treatment or further monitoring is needed.
