URGENT UROLOGICAL REFERRAL & SAFETY-NETTING (NO DRUG THERAPY)
Children are the exception to the cancer logic - isolated haematuria in a child generally does well, and it is the company it keeps (proteinuria, hypertension, impaired renal function) that points to glomerular disease and a worse outlook. Refer to paediatric nephrology, not to urology, when those are present.
Gross and Microscopic Hematuria - disease-level clinical article (microscopic-haematuria-referral-full.txt)
There is no primary-care drug for visible haematuria. The action is referral and the reason is the source's own: visible blood places the patient in a high-risk category regardless of symptoms, and the chance of finding a urinary-tract cancer rises from about 3% with microscopic blood to 10-20% when it is visible.
- Refer even when the blood has stopped. A single episode that cleared is still visible haematuria and still carries the risk.
- Refer even when the patient is on an anticoagulant. Anticoagulation does not explain haematuria and does not exclude underlying disease.
- A urinary tract infection is the commonest benign explanation, but it is only an explanation once treated and the urine has been rechecked and is clear.
- In Egypt, urinary schistosomiasis is a leading cause and its own source calls visible haematuria the most characteristic presenting symptom of S haematobium infection. Ask about canal or Nile water exposure - see the Schistosomiasis card.
- Chronic urinary schistosomiasis is a route to bladder cancer, so finding bilharzia does not close the question of malignancy in an older patient.
- Full evaluation is imaging, urine cytology and cystoscopy - a normal ultrasound alone does not clear the bladder.
