Intravenous pyelogram

Excretory urography; IVP

An intravenous pyelogram (IVP) is a special x-ray exam of the kidneys, bladder, and ureters (the tubes that carry urine from the kidneys to the bladder).

Kidney anatomy

The kidneys are responsible for removing wastes from the body, regulating electrolyte balance and blood pressure, and the stimulation of red blood cell production.

Kidney - blood and urine flow

This is the typical appearance of the blood vessels (vasculature) and urine flow pattern in the kidney. The blood vessels are shown in red and the urine flow pattern in yellow.

Intravenous pyelogram

An intravenous pyelogram is performed by injecting contrast material into a vein in the arm. A series of x-rays are taken at timed intervals as the contrast material goes through the kidneys, the ureters (the tubes connecting the kidneys to the bladder), and the bladder. The procedure helps to evaluate the condition of the kidneys, ureters, and bladder.
