Antegrade Pyelography

Antegrade pyelography uses a special dye to see detailed x-ray images of the upper urinary tract (kidney and ureter).

Archived from the 2022 edition

Overview

It is used to diagnose hydronephrosis, ureteropelvic junction (UPJ) obstruction and obstruction of the ureters, for example.

This exam may be done in a hospital or in a doctor's office by a radiologist or x-ray technician. To begin, dye is injected right into the kidneys. This allows them to be seen more clearly on x-ray.
