Related to retrograde pyelography: intravenous pyelography, antegrade pyelography

ret·ro·grade py·e·log·ra·phy

pyelography in which contrast material is injected into the ureters from an endoscope in the bladder.

retrograde pyelography

a radiological technique for examining the structures of the collecting system of the kidneys that is especially useful in locating a urinary tract obstruction. A radiopaque contrast medium is injected through a urinary catheter into the ureters and the calyces of the pelves of the kidneys. Rarely, severe anaphylactoid reaction to the medium may occur because of a patient's hypersensitivity to the iodine in the medium, and infection or trauma may result from the catheterization.

retrograde pyelography

Retrograde urography Imaging A method for visualizing the renal collecting system–ie, the pelvis and lower urinary tract, based on the excretion of radiocontrast after injection into the renal pelvis or ureter via a ureteral catheter Indications Suspected kidney disease–eg, pyelonephritis, kidney stones, or right upper quadrant colic

pyelography

radiography of the kidney and ureter after injection of a contrast medium, introduced by the intravenous or retrograde method. Preparation of the animal for pyelography includes clearing the intestinal tract of as much fecal material and gas as possible so that there can be adequate visualization of the urinary tract structures. Called also intravenous pyelography (IVP).
