Abdominal X-ray

Abdominal X-ray (Kidney, Ureter, and Bladder Radiography,
KUB, Flat Plate X-ray of the Abdomen, Scout Film)
Test Description
The abdominal x-ray, often referred to as a flat plate of the abdomen or KUB, provides an overall view of the lower abdomen that shows the position of the kidneys, ureters, and bladder. The ureters are not normally visible on the KUB unless abnormal, as when calculi are present. The test is a simple x-ray film with the patient in a supine position. It requires no physical preparation of the patient. Renal enlargement, renal displacement, congenital anomalies, and renal or ureteral calculi are just a few of the abnormalities that may be seen as a result of this test. In addition to abnormalities of the urinary tract, the KUB may be used to assess for the presence of ascites and for gas within the intestines, which may occur with intestinal obstruction.
