In medicine, KUB refers to a diagnostic medical imaging technique and stands for Kidneys, Ureters, and Bladder.

 

A KUB is a plain frontal supine radiograph of the abdomen. It is often supplemented by an upright PA view of the chest (to rule out air under the diaphragm or thoracic etiologies presenting as abdominal complaints) and a standing view of the abdomen (to differentiate obstruction from ileus by examining gastrointestinal air/water levels).

 

Despite its name, a KUB is not typically used to investigate pathology of the kidneys, ureters, or bladder, since these structures are difficult to assess (for example, the kidneys may not be visible due to overlying bowel gas.) In order to assess these structures with X-ray, a technique called an intravenous pyelogram is utilized.

 

KUB is typically used to investigate gastrointestinal conditions such as a bowel obstruction and gallstones, and can detect the presence of kidney stones.

This is called a KUB. K stands for kidney, U stands for ureter and B stands for bladder. The doctor has put some dye into the blood vessels before taking the x-ray so that the urinary tract (made up of the 2 kidneys, 2 ureters and bladder) can be seen.
