Quick Summary

Intravenous pyelography is a medical procedure that uses X-rays to examine the urinary tract. A contrast fluid, typically an organic iodine derivative, is injected intravenously. This fluid is quickly excreted in the urine, allowing it to cast an X-ray shadow. This technique, a type of urography, helps detect abnormalities such as kidney stones, tumors, and obstructions. Specifically, pyelography focuses on examining the kidney and ureter, and a ureteropyelogram is an X-ray photograph of the kidney pelves and ureters taken after they are filled with a radiopaque substance.12

Diagnosis
An X-ray imaging procedure called intravenous pyelography, in which an injectable dye travels into the urinary tract and enhances X-ray image contrast, may also be used; abnormalities seen on the film may indicate the presence of cancer. In addition, laboratory tests can detect specific chemical markers that indicate cancer.
