Colour Doppler adds blood-flow information to a standard kidney scan, showing how blood moves through the renal arteries and within the kidneys.
Measure both kidneys and look for scarring, cysts or stones.
Look for narrowing (renal artery stenosis) that can raise blood pressure.
Measure resistance to flow within each kidney.
A check of the bladder where helpful.
A kidney (renal) colour Doppler ultrasound is a non-invasive imaging test used to assess the structure and blood flow of the kidneys, ureters, and bladder. It is commonly used to investigate renal artery stenosis, renal vascular disease, kidney cysts, renal masses, kidney stones, urinary tract infections, and high blood pressure related to kidney conditions. The scan evaluates both the structural and functional aspects of the kidneys, helping to detect abnormalities such as blood clots, tumours, and areas of reduced blood flow.
Whether you’ve been referred by your GP or are self-referring, our experienced sonographers provide clear, accurate results in a comfortable and private setting, with same-day results and no GP referral needed.
Kidney Colour Doppler Ultrasound is a non-invasive imaging technique that uses sound waves to create detailed images of the blood flow within the kidneys. It is a crucial diagnostic tool for identifying various kidney conditions, including:

No. You can book directly. If your GP or specialist has asked for this scan, bring their letter so the sonographer knows what to focus on.
Narrowing of a kidney artery is a treatable cause of high blood pressure, especially in younger people or when blood pressure is hard to control.
Severe tummy pain, a high temperature, vomiting that will not stop or yellowing of the skin needs urgent advice: contact NHS 111 or your GP, or call 999 in an emergency. Do not wait for a private scan.
A Color Doppler ultrasound is a diagnostic imaging technique that combines traditional ultrasound with Doppler technology to visualize blood flow within the kidneys, ureters, and bladder. It allows for the assessment of both structural and functional aspects of these organs.
This ultrasound is performed to evaluate a range of conditions affecting the kidneys, ureters, and bladder, including kidney stones, urinary tract infections (UTIs), kidney cysts, tumors, renal artery stenosis, and urinary obstruction. It can also assess blood flow to the kidneys and detect abnormalities such as renal artery or vein thrombosis.
Do NOT eat for 6 hours prior to examination time. Drink One liter of still water (2 Pints) One hour before your scan.
The ultrasound provides detailed images of the kidneys, ureters, and bladder, allowing for the assessment of organ size, shape, and texture. Additionally, it evaluates blood flow within these structures, detecting abnormalities such as blood clots, tumors, or areas of decreased perfusion.
The frequency of Color Doppler ultrasound varies depending on the individual’s medical history, symptoms, and the presence of underlying conditions. It may be performed as needed for diagnostic purposes or as part of routine monitoring for certain conditions. Color Doppler ultrasound of the kidneys, ureters, and bladder is a valuable tool in the diagnosis and management of urological conditions. It provides detailed information about organ structure and blood flow, assisting healthcare providers in delivering optimal patient care.
