Abdomen Ultrasound
A scan of the liver, gallbladder, pancreas, spleen, kidneys and other organs of the abdomen.
KUB Ultrasound
An ultrasound of the kidneys, ureters and bladder to check for stones, swelling and other problems.
About this scan
KUB stands for Kidneys, Ureters and Bladder — the main parts of the urinary system. A KUB ultrasound looks at the size and shape of the kidneys, checks for stones, and looks for swelling of the kidneys (hydronephrosis) or problems with the bladder.
It is often requested for flank or lower back pain, blood in the urine, repeated urine infections or difficulty passing urine. The scan is painless and uses no radiation, so it is suitable for adults and children.

Preparation & tips
How to get ready for your scan, and what to expect afterwards.
If you have sudden or severe symptoms, please seek urgent medical care.
Drink 4–5 glasses of water about an hour before the scan and do not pass urine, so the bladder is full. Our team will confirm the exact preparation.
Bring any previous scans or urine test results.
You can return to your usual activities straight away.
KUB Ultrasound: common questions
Why do I need a full bladder?
A full bladder is easier to see on ultrasound and allows the bladder wall and its contents to be examined properly.
Can ultrasound detect kidney stones?
Ultrasound can show many kidney stones and any swelling of the kidney they cause. Very small stones or stones in the ureters can be harder to see, and your doctor may suggest other tests if needed.
