Do I really need to see a doctor for blood in my urine?

Yes. If blood is visible to the naked eye (gross hematuria) or keeps recurring, see a urologist for a full workup.

What are the main causes of hematuria?

Causes include nephritis, urinary tract infection, kidney stones, bladder cancer, benign prostatic hyperplasia (BPH), and prostate cancer.

Is microscopic hematuria dangerous?

It causes no symptoms, so it is easy to overlook, but an underlying condition may be present — regular check-ups matter.

Do the causes of hematuria change with age?

Yes. Younger people more often have urinary tract infections and stones; those 50 and older, bladder cancer and prostate conditions.

Hematuria

Blood in your urine can be a warning sign of a urinary tract problem.

Blood in your urine?
Ignoring it could lead to cancer.

Hematuria, explained by urology specialist Dr. Min Seungki on Goldman TV

VIEW

Hematuria can be an early sign of a serious condition such as urologic cancer or kidney disease.
If you have visible blood in your urine, the cause should be identified and treated through a detailed workup.

What is hematuria?

Hematuria is a symptom in which abnormal red blood cells appear in the urine, meaning that bleeding has occurred somewhere in the urinary tract.
It is divided into gross hematuria, which is visible to the naked eye, and microscopic hematuria, which can only be detected through testing.

Hematuria — if you see it, you need accurate, age-appropriate testing.

The causes of hematuria vary with age. In younger people it may be a urinary tract infection (UTI) or stones,
while in those aged 50 and over it may be a condition of the kidneys, bladder, or prostate, so diagnosis tailored to each age group is required.

Hematuria: why does it happen?

Hematuria can occur anywhere along the urinary tract that urine passes through, so its causes are extremely varied.
A comprehensive examination from the kidneys to the prostate is needed, and because in some cases it may be a sign of kidney disease or a tumor, an accurate diagnosis is important.

Kidney causes

Kidney causes include pyelonephritis, glomerulonephritis, tumors, glomerular vascular abnormalities, and stones.

Ureteral causes

Ureteral causes include ureteral cancer and stones.

Prostate Causes

Prostate causes include prostatitis, benign prostatic hyperplasia, and prostate cancer.

Bladder Causes

In the bladder, bladder cancer or bladder stones can cause hematuria.

Diagnosing hematuria:
what methods are available?

If hematuria is suspected, a urinalysis is performed first to confirm whether blood is present in the urine.
If hematuria is observed consistently in 3 times or more urinalyses, further examination is needed to identify the exact cause.

Medical Interview and History Taking

A detailed interview on your symptoms, urination habits, and medical history gives clues to the cause.

Urinalysis

First-morning or midstream urine is tested three times; if red blood cells exceed the reference level, further tests follow.

Ultrasound Examination

It is used to diagnose kidney and bladder tumors, urinary tract obstruction, and orchitis; the prostate is examined by transrectal ultrasound.

Cystoscopy

Checks for bladder cancer and stones; recommended to find the cause of hematuria in people 50 and older.

Tissue Biopsy

If cystoscopy shows abnormal findings, further tests are done with your consent.

Intravenous Pyelography (IVP)

Contrast dye is injected to image how the kidneys, ureters, and bladder excrete urine.

Urinalysis is done three times to confirm hematuria.

Further testing is needed if 3 or more red blood cells per HPF appear at least twice, 100 or more appear even once, or blood is visible to the naked eye.

Hematuria treatment:
how is it carried out?

Microscopic hematuria has no symptoms and is often found late, so a yearly urinalysis matters.

If you see blood in your urine, visit the clinic for a detailed exam so the cause can be treated quickly.

Treating Infectious Causes

Infection-related hematuria needs early antibiotics.Prompt treatment keeps symptoms from worsening and prevents complications.
Treating Structural Problems

Structural causes such as stones, tumors, and obstruction are treated with surgery or a procedure.An accurate diagnosis guides the right treatment.
Treatment for Other Causes

Treatment depends on the cause.Inflammation is treated with anti-inflammatory and medical therapy; other underlying conditions are treated accordingly.
