The kidneys filter your blood and make urine, the ureters carry it down and the bladder stores it. Ultrasound shows each part clearly, using sound waves rather than radiation.
Measure both kidneys and look at their shape and tissue for signs of kidney disease or scarring.
Look for kidney stones and for swelling of the kidney (hydronephrosis) that can mean urine is not draining well.
Identify simple cysts, polycystic change and growths that may need further assessment.
Check the bladder wall and contents, and how much urine is left after you go to the toilet.
A Kidneys, Ureters, and Bladder (KUB) ultrasound is a safe, non-invasive scan that gives clear images of your urinary system. It is essential for detecting kidney stones, tumours, cysts, and other urinary tract abnormalities. By using sound waves to create detailed images, this scan plays a vital role in diagnosing and monitoring urinary tract health.

A question before you book? Call usPain in your side or back, burning or frequent urination, blood in the urine or a known kidney condition — let the sonographer know.
Gel is applied and the probe is moved over your sides, back and lower tummy. You may be asked to empty your bladder part-way so it can be checked again. It is painless and takes about 20 minutes.
The sonographer explains what they have seen, and your written report follows within 24 hours — ready to share with your GP or urologist.

Speak to the team before booking.
No. You can book directly. If you have a referral letter or recent results, bring them along so the scan can focus on the right questions.
A full bladder stretches out its wall so it can be seen and measured clearly. Drinking 1 litre of water an hour before and not using the toilet gives the best view.
Ultrasound shows most kidney stones and any swelling of the kidney they cause. Very small stones, or stones lower down in the ureters, can be harder to see, and your doctor may suggest a CT scan if symptoms continue.
Yes. It can look for things that make infections more likely, such as stones, a blockage or a bladder that does not empty fully. It does not test the urine itself — your GP can arrange that.
Severe pain in your side, a high temperature with shivering, or being unable to pass urine needs urgent advice: contact your GP or NHS 111, or call 999 in an emergency. Do not wait for a private scan.
