Quick Summary

Pyelography is a medical imaging technique that uses X-rays to examine the kidneys and ureters. This procedure involves introducing a radiopaque substance, typically an organic iodine derivative, into the urinary tract. This contrast fluid casts an X-ray shadow, allowing visualization of the urinary system.1

Pyelography can help detect various conditions, including tumors, kidney stones, and obstructions caused by an enlarged prostate. A ureteropyelogram specifically refers to an X-ray photograph of the kidney's pelvis and ureters after they have been filled with a radiopaque substance.12
