Blood in urine: when should you see a urologist?
Why visible or non-visible blood in the urine should be assessed rather than ignored.
Quick answer
Blood in urine should be discussed with a clinician. Visible blood, recurrent blood or blood with risk factors often needs specialist assessment.
What this can mean
Blood in urine can come from infection, stones, prostate conditions, kidney causes or bladder problems. Occasionally it can be a sign of cancer.
Assessment may involve urine tests, scans and cystoscopy depending on age, symptoms and risk factors.
How specialist assessment may help
- Take a history of visible or microscopic haematuria.
- Check for infection and stone symptoms.
- Consider imaging of kidneys and urinary tract.
- Discuss cystoscopy if bladder assessment is needed.
Questions to ask at your appointment
- Was the blood visible?
- Could it be infection or stones?
- Do I need cystoscopy?
- What scans are appropriate?
Common questions
Can blood in urine be harmless?
Sometimes, but it should be assessed because important causes need excluding.
Should I wait if it stops?
You should still seek advice, especially after visible blood in urine.
