Blood in Urine Evaluation in Seomyeon, Busan

A blood in urine (hematuria) evaluation finds the source of red or microscopic blood in the urine (혈뇨), which may come from infection, stones, an enlarged prostate, kidney disease or, less commonly, bladder or kidney cancer. In Seomyeon, Busan, urology clinics usually start with urine tests and ultrasound in one visit, then arrange CT and cystoscopy depending on age and risk.

What is hematuria?

Hematuria means red blood cells in the urine. Visible hematuria turns urine pink, red or cola-coloured. Microscopic hematuria is found only on a urine test, often during a routine health check. Some foods (such as beetroot), medicines and intense exercise can discolour urine or cause temporary blood, but persistent or visible blood always deserves assessment.

Symptoms and when to see a doctor

  • Pink, red or brown urine, with or without clots
  • Blood with burning or frequent urination (often infection)
  • Blood with severe flank pain (often a stone)
  • Painless visible blood, which needs prompt evaluation to exclude bladder or kidney cancer
  • Microscopic blood reported on a health check

Go to an emergency department or call 119 if clots block urination, bleeding is heavy, or you feel faint.

What happens at the clinic

  1. History: colour, timing, pain, smoking, occupation, medications such as blood thinners, recent exercise or infection.
  2. Urine tests: dipstick, microscopy to confirm red cells, culture and sometimes cytology.
  3. Blood tests: kidney function; PSA for men in some cases.
  4. Ultrasound: kidneys, bladder and prostate.
  5. CT urography: detailed imaging of the urinary tract for visible blood or higher-risk patients.
  6. Cystoscopy: a thin flexible scope views the bladder lining directly.
  7. Referral: to nephrology if protein in urine or kidney function changes suggest kidney disease.

Treatment outlook

Many causes are benign and treatable: infections clear with antibiotics, stones pass or are removed, and prostate bleeding can be managed with medication. When no cause is found after a full work-up, the outlook is usually good, with periodic urine checks. If a tumour is found, early detection allows less extensive treatment.

Risks and side effects

Ultrasound is risk-free. CT involves radiation and contrast dye, which is checked against kidney function and allergies. Flexible cystoscopy can cause brief stinging and a small risk of urinary infection.

Choosing a clinic for hematuria evaluation in Seomyeon

  • Choose a urology clinic that can do ultrasound and flexible cystoscopy on-site.
  • Ask whether CT urography is arranged in-house or by referral and how quickly.
  • Ask how results will be followed up if the first tests are normal.
  • Bring results from any health check that found blood in urine.
  • Tell the doctor about all medicines, especially blood thinners.

Key facts

  • Types: visible (gross) or microscopic (found on a urine test)
  • First tests: urinalysis, microscopy, culture, kidney function blood test
  • Imaging: kidney and bladder ultrasound; CT urography for higher-risk cases
  • Bladder check: flexible cystoscopy, usually under local anesthetic gel, about 5–10 minutes
  • Higher-risk factors: age over about 40, smoking, visible blood, chemical exposure
  • Urgent: clots with inability to urinate, or heavy bleeding with dizziness
  • Never ignore: visible blood even if it stops

Frequently asked questions

Is blood in urine always serious?

Not always. Infections, stones and exercise are common causes. However, visible blood, especially without pain, should always be checked because it can be an early sign of bladder or kidney cancer.

What is a cystoscopy like?

A thin flexible camera is passed through the urethra after numbing gel. It takes about five to ten minutes. Most people feel pressure and stinging rather than significant pain.

My health check found microscopic blood. What next?

The urine test is usually repeated. If blood persists, a urologist will typically order urine microscopy, kidney function tests and ultrasound, and decide on further tests based on your age and risk factors.

Can exercise cause blood in urine?

Yes. Intense exercise such as long-distance running can cause temporary blood in urine. It should clear within a couple of days; if it persists, get it checked.

Do blood thinners cause hematuria?

Blood thinners can make bleeding more likely, but they rarely cause hematuria on their own. Doctors still investigate for an underlying cause.
