Retrograde pyelography is a form of x-ray used to get detailed pictures of the ureters and kidneys. Retrograde pyelography uses a special dye (“contrast agent”) injected into the ureters. The dye makes the ureters and kidneys more easily seen on the x-ray. This test is like an intravenous pyelogram (IVP).Click to see full answer. Also, what is a retrograde pyelogram used for?A retrograde pyelogram is an imaging test that uses X-rays to look at your bladder, ureters, and kidneys. The ureters are the long tubes that connect your kidneys to your bladder. This test is usually done during a test called cystoscopy. It uses an endoscope, which is a long, flexible, lighted tube.Secondly, what type of contrast is used in retrograde pyelogram? The contrast that is used for retrograde pyelography is the same that is used for excretory urography (intravenous urography). Contrast is categorized by osmolality, of which there are 3 groups: isoosmolar, low osmolar, and high osmolar. Besides, what does retrograde Pyelogram mean? A retrograde pyelogram is a urologic procedure where the physician injects a radiocontrast agent into the ureter in order to visualize the ureter and kidney with fluoroscopy or radiography. Fluoroscopy, or dynamic X-rays, is typically used for visualization.How is a Pyelogram performed?During an intravenous pyelogram, you’ll have an X-ray dye (iodine contrast solution) injected into a vein in your arm. The dye flows into your kidneys, ureters and bladder, outlining each of these structures.
