Urology(비뇨의학과) is generally the first specialty to evaluate blood in the urine, as urologists manage conditions affecting the kidneys, ureters, bladder, and urethra. Depending on findings, care may extend to Nephrology(신장내과) if a kidney-related internal medicine issue is suspected, or to other specialties based on what a doctor determines.
Which department
- 1Urology (비뇨의학과)Urologists specialize in the urinary tract as a whole — from the kidneys down to the urethra — and are trained to evaluate structural or functional causes of blood appearing in urine. This makes them the most common first point of contact for this symptom in general practice. — First / second line: In many cases, visiting a local urology clinic (의원) first is a common approach in the Korean healthcare system. If imaging or further specialist evaluation is needed, the clinic may provide a referral letter (진료의뢰서) to a larger hospital.
- 2Nephrology (신장내과)Nephrologists focus on kidney function and internal medicine-related kidney diseases; blood in the urine can sometimes originate from conditions within the kidney tissue itself rather than the urinary tract structures. — First / second line: A patient is typically referred to nephrology from urology or internal medicine when test results suggest a kidney-origin cause rather than a structural or urological one. Direct first visits to nephrology are less common but possible if kidney disease is already known.
- 3Internal Medicine (내과)If a patient is unsure where to start, or if blood in the urine appears alongside general systemic symptoms, a general internal medicine clinic can perform an initial urine test and direct the patient to the appropriate specialist. — First / second line: Visiting an internal medicine clinic first is a reasonable option, especially at a local 의원 level, when the cause is unclear; the doctor can then coordinate onward referral based on findings.
- 4Gynecology (산부인과) — for female patientsIn female patients, it can sometimes be difficult to determine whether blood is originating from the urinary tract or from the reproductive system, so a gynecology consultation may be relevant in ambiguous cases. — First / second line: This is generally not the first department to visit for confirmed urinary blood, but a gynecologist may be consulted alongside urology when the source of bleeding is unclear in female patients.
Go to the ER / call 119 if
If any of the following applies, do not choose a department — go to an emergency room or call 119 (Korea's emergency number).
- Large amounts of visible blood in the urine, especially with the urine turning dark red or brown, combined with rapidly worsening pain or dizziness.
- Sudden, severe flank or lower back pain accompanied by blood in the urine and inability to find a comfortable position.
- Blood in the urine together with high fever, chills, and significant difficulty urinating.
- Loss of consciousness, extreme weakness, or a very rapid drop in blood pressure alongside urinary bleeding.
- Complete inability to urinate despite a strong urge, combined with visible blood in the urine.
Before your visit
- Note when you first noticed blood in the urine and whether it appeared at the beginning, end, or throughout urination.
- Observe the color of the urine — bright red, dark brown, pink, or clot-like — and write it down before your visit.
- Record any accompanying symptoms such as pain during urination, flank pain, fever, frequent urination, or a feeling of incomplete emptying.
- Make a list of all medications and supplements you are currently taking, including any blood thinners, as these can be relevant.
- Bring results of any previous urine tests, imaging, or kidney-related examinations if available.
- Note any relevant personal or family medical history, such as kidney stones, urinary tract infections, or kidney disease.
General principles
Blood in the urine — medically referred to as hematuria — can be visible to the naked eye (gross hematuria) or detectable only through a urine test (microscopic hematuria). Because the urinary tract spans from the kidneys to the urethra, identifying the source requires evaluation of the entire system, which is why urology is generally the primary specialty involved.
In the Korean healthcare system, the general flow tends to start at a local clinic (의원) level, where a urine test is often the first step. Depending on the result, the doctor may refer the patient to a hospital with imaging or endoscopy capabilities; a referral letter (진료의뢰서) is particularly important when visiting a tertiary hospital (상급종합병원), as it is required to maintain standard coverage under the national health insurance (건강보험) system.
The range of possible underlying causes for blood in the urine is broad — from minor irritation to more significant conditions — so the role of the doctor is to narrow down the cause through history-taking and appropriate tests. General principles of evaluation typically involve ruling out infection, stones, and structural abnormalities before considering other causes.
Because some causes of blood in the urine require prompt attention while others are less urgent, a doctor's assessment is the essential first step before any conclusions can be drawn about severity or next steps.
FAQ
Should I go to a local clinic (의원) or a large hospital directly for blood in the urine?
In most non-emergency situations, starting at a local urology or internal medicine clinic is generally the approach that aligns with the Korean healthcare system, as clinics can perform initial urine tests and provide referrals if needed. Going directly to a secondary hospital (병원/종합병원) without a referral is possible and still covered at normal insurance rates, though visiting a tertiary hospital (상급종합병원) without a referral letter does involve higher out-of-pocket costs under the national health insurance system. However, if symptoms are severe or accompanied by red-flag signs, skipping the clinic and going to an emergency department is more appropriate.
How is blood in the urine different from other causes of discolored urine?
Certain foods (such as beets), medications, or metabolic conditions can also cause urine to appear red or brown without actual blood being present. A simple urine dipstick or microscopy test performed by a doctor can generally distinguish true blood from other colorants. This is one reason why a medical evaluation is important rather than drawing conclusions from urine color alone.
What kinds of tests are generally done to investigate blood in the urine?
A doctor will typically begin with a urine analysis to confirm the presence of blood and look for other abnormalities. Depending on the initial findings, additional evaluations may follow — such as imaging of the urinary tract or further blood tests — but the specific tests chosen depend entirely on the clinical picture as assessed by the doctor. No particular test or procedure should be assumed to be necessary before a consultation.
Is the evaluation different for children or older adults with blood in the urine?
The general approach of consulting urology or internal medicine still applies across age groups, but the range of conditions a doctor considers may differ — for example, certain kidney conditions are more common in children, while other causes may be more prevalent in older adults. In both groups, a medical evaluation is equally important, and a pediatrician (소아청소년과) may be the appropriate first contact for younger children before specialist referral.
