Pyelogram
Pyelogram (or pyelography or urography) is a form of imaging of the renal pelvis and ureter. Types include: * Urogram (also intravenous urography) – In which a contrast solution is introduced through a vein into the circulatory system. * Retrograde pyelogram – Any urography 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 urography) – A urography where a contrast medium passes from the kidneys toward the bladder, mimicking the normal flow of urine. * Gas urography – A urography that uses a gaseous rather than liquid contrast medium. It may also form without the injection of a gas, when gas producing micro-organisms infect the most upper parts of urinary system.
