Types include:

  • Intravenous pyelogram – In which a contrast solution is introduced through a vein into the circulatory system. This is a form of anterograde pyelogram.
  • Retrograde pyelogram – Any pyelogram in which contrast medium is introduced from the lower urinary tract and flows toward the kidney (i.e. in a "retrograde" direction, against the normal flow of urine).
  • Anterograde pyelogram (also antegrade pyelogram) – Any pyelogram where a contrast medium passes from the kidneys toward the bladder, mimicking the normal flow of urine.
  • Gas pyelogram – A pyelogram that uses a gaseous rather than liquid contrast medium.[2]
