Antegrade Pyelography

Antegrade pyelography is a diagnostic test performed to create detailed X-ray images of the kidneys and ureters with the help of a contrast dye. This test may be performed to diagnose some of the following conditions:

  • Ureteropelvic junction obstruction
  • Hydronephrosis
  • Obstruction of the ureter

Antegrade Pyelography Procedure

Antegrade pyelography begins with an ultrasound or CAT scan examination to locate the kidneys. Once the kidneys have been located, an anesthetic is applied to the skin around the affected area and a contrast dye is injected into them. Finally, X-rays are taken of the kidneys and the examination is then complete. Day-to-day activities can be resumed immediately afterwards.

Risks Or Complications Of Antegrade Pyelography

Antegrade pyelography is generally a safe examination, with a few associated risks. Some of these risks may include:

  • Allergies to the contrast dye
  • Nausea
  • Hot flashes
  • Vomiting

In very rare circumstances, more serious complications may occur such as:

  • Breathing difficulties
  • Low blood pressure
  • Swelling of the mouth or throat
  • Cardiac arrest

Antegrade pyelography exposes patients to relatively low amounts of radiation, so patients who are or may be pregnant should notify their doctor before undergoing an antegrade pyelography.
