Intravenous Pyelogram

Also known as: IVP.

What is intravenous pyelogram?

Intravenous pyelogram (IVP) is a form of X-ray. It gives health care providers a better view of how waste fluid flows through the renal and urinary system by highlighting the bladder, ureters and kidneys with a special dye.

What happens during the procedure?

As the patient lies on his or her back, a special “scout” X-ray is performed first. Then the contrast dye is injected into a vein. After allowing time for the dye to move to the kidneys, ureters and bladder, a series of additional X-rays are taken. These are then analyzed to look for problems in the renal and urinary systems.

Is any special preparation needed? 

Patients are on a restricted diet for 24 hours before intravenous pyelogram. They also must urinate the night before in order to have an empty bladder for the test.

What are the risk factors?

Nausea, vomiting, breathing problems, low blood pressure, mouth and throat swelling and allergic reactions are all possible complications of intravenous pyelogram.
