How common is blood in urine in upper tract urothelial cancer?

Upper tract urothelial cancer starts in the lining of the kidney drainage system or ureter. Bleeding from this lining can make urine pink, red, or brown, or blood may be detected only by testing. It may come and go and may occur without pain. Blood in urine is not specific to cancer: infection, stones, kidney conditions, medicines, and other urinary problems can produce the same sign.

Assessment usually considers the pattern of bleeding, urinary symptoms, pain, smoking or chemical exposures, previous urinary conditions, and general health. Tests may include urine analysis, blood tests, imaging of the urinary tract, and a specialist examination. The exact combination depends on your symptoms and clinical findings.

Arrange medical review for visible blood in urine, even when it has stopped and even when there is no pain. Record when it happened, its colour, whether clots were present, and any burning, urgency, fever, or side pain. Bring a list of medicines and relevant previous urinary problems. Your clinician may request a urine sample and refer you for imaging or urology review so the source of bleeding can be identified.

Get urgent help if you cannot pass urine, pass clots, have severe side or back pain, feel faint, or have heavy or persistent bleeding. Fever with urinary symptoms can signal an infection requiring prompt treatment. New weakness, confusion, or very low urine output should also be treated as urgent.

Ask what tests will identify the bleeding source, whether you need a urology referral, and how quickly the assessment should happen. You can also ask whether medicines or infection could contribute, what changes should prompt urgent care, and how results will be explained if the bleeding returns.
