What Is an Abdominal Film?

An abdominal film, also known as an abdominal X-ray, helps your doctor assess potential problems in your abdominal cavity, stomach, and intestines. Your doctor may perform this procedure to help detect a particular condition such as kidney stones or gallstones.

Instead of examining the entire abdominal area, your doctor may order a KUB X-ray, which is a variation of an abdominal film that focuses on the kidneys, ureters, and bladder. The procedure gets its name from the first letter of each of these body parts
