intravenous pyelography (IVP)


A procedure used to x-ray the kidney, ureter and bladder. A contrast medium is injected into a vein and x-ray images are taken at regular times to record how it passes through the organs into the urine.

Doctors use intravenous pyelography to test how well the kidneys are working and to look for tumours, stones or blockages in the urinary system.

The x-ray image produced is called an intravenous pyelogram (IVP).
