X-rays of the kidneys, ureters and bladder, known as KUB x-rays, are taken for many reasons, including finding the cause of abdominal pain or vomiting. In children they often reveal constipation, which can contribute to urinary incontinence or help locate possible kidney stones.

Physicians can use KUB x-rays to confirm an intestinal blockage or foreign objects in the stomach. This test has become less common in recent years because pediatric urologists can often use physical examinations and other noninvasive tests to diagnose patients.

What to Expect

What to Expect

Children who have this procedure do not need to bring anything to the appointment. The procedure may take several minutes. Your child removes any jewelry and wears a hospital gown. To minimize radiation exposure, a lead apron covers parts of the body that are not x-rayed.

Since different views may be needed, your child may be moved in different positions to get the necessary images. There should be no pain with this procedure unless your child has had a recent surgery or procedure that makes positioning his/her body difficult. After the test, a radiologist reviews the x-rays. Additional tests may be necessary to make a complete diagnosis.

Returning Home

Returning Home

KUB tests are performed as an in-patient or outpatient procedure. Generally, there are no special instructions after the test, and your child can resume normal activities.

Key Points to Remember

Key Points to Remember

  • KUB x-rays take images of the kidneys, ureter and bladder.
  • This procedure may be used to determine why a child has abdominal pain or vomiting. A KUB x-ray may also help find kidney stones, an intestinal blockage or constipation.
  • The test may take several minutes depending on the number of positions and x-rays needed to get a complete picture.
