Intravenous Pyelogram

Intravenous Pyelogram Introduction

Intravenous pyelography refers to a series of X-rays taken of the kidneys, their collecting or drainage system (the ureters), and the bladder. The ureters are the small tubelike structures that connect the kidneys to the bladder.

  • An intravenous pyelogram (IVP) may be performed to detect a problem of the kidneys, ureters, and bladder. Most often, the IVP is done to locate a suspected obstruction to the flow of urine through the collecting system. The most common cause of blockage is a kidney stone. The IVP test also gives information about the functioning of the kidneys.
  • In an IVP test, dye is injected via a catheter inserted in a person's vein, usually on the hand or the forearm. X-rays are then taken to follow the track of the dye through the system.
