What is KUB X-Ray?
A KUB (kidney, ureter, bladder) X-ray is a painless radiology exam. This is performed to examine the cause of unexplained pain and discomfort in the abdominal area in a non-invasive manner.
In this scan, multiple images of the bones and soft tissues of the kidney, ureter, and bladder are generated. KUB X-ray is mainly useful in emergency diagnosis and treatment because it is a quick and easy scan.
The KUB X-ray helps doctors in assessing the size and position of the kidneys, bladder, and ureters. It also helps them in the diagnosis of urinary disorders and detection of inflammatory conditions, tumors, and injuries.

Who Should Get a KUB X-Ray?
Your doctor may recommend a KUB X-ray if you have:
- Experienced an acute trauma or injury to your abdominal area.
- Severe pain in the abdominal region and/or lower back.
- Unexplained nausea and vomiting.
- Increase or decrease in the frequency of urination
What is the Purpose of a KUB X-Ray?
A KUB X-ray will help your doctor:
- Evaluate unusual pain in the abdominal area with uncommon symptoms.
- Find the cause of unexplained vomiting.
- Detect kidney stones (hard masses formed in the kidneys) and certain types of gallstones (hard lumps formed in the gallbladder).
- Detect blockage in the intestines.
- Detect cysts, tumors, and other diseases in the kidneys, ureters, and bladder.
- Check if an object swallowed by a person is present in the stomach.
- Check the proper placement of a ureteral stent (a small tube) that is placed to allow urine to flow from the kidney to the bladder when the normal flow is blocked.
Your doctor may also ask you to take the Abdominal Ultrasound to confirm the diagnosis for abnormalities in the abdominal area. Depending on the results, your doctor will confirm the diagnosis and plan your treatment.
How is a KUB X-Ray Performed?
- Before starting the KUB X-ray, you will have to remove all the metal objects on your body including eyeglasses, jewelry, hairpins, and dentures.
- A technologist will ask you to either stand upright or lie down on your back on a special radiology table, depending on the type of X-ray machine available at the diagnostic center.
- The X-ray machine will be placed in front of your abdomen, while a specialized plate containing the X-ray film will be positioned behind your back.
- The X-ray machine will then send a beam of X-ray radiation through your abdomen and will take an image that will be displayed on a monitor.
- During the scan, the technologist will ask you to sit still and hold your breath for a few seconds at certain points. Make sure you don’t move during the scan as any movement can blur the images.
How Long Does a KUB X-Ray Take?
A KUB X-ray is usually completed within 15 minutes, but the actual exposure time to radiation is usually less than a second.
Is Radiation Involved in a KUB X-Ray?
Yes. An X-ray is an imaging test that involves a small amount of radiation to show images of the organs, tissues, and bones of the body.
Are There Any Risks in Taking a KUB X-Ray?
- The risk for radiation exposure is low in a single X-ray. However, the effect of radiation and the risk of developing cancer due to radiation increases with every X-ray a person gets.
- Developing babies are sensitive to radiation and are at more risk, so women should inform their doctors and the X-ray technicians if they are pregnant.
When Will I Receive My Results?
Once the KUB X-ray is completed, you will receive your results within 3-5 business days in your LabFinder portal.
