Question

What medical procedure involves the injection of iodine using a ureteral catheter to visualize the kidneys and ureters, often used to confirm intravenous urography (IVU) findings or when IVU results are insufficient?

a) Retrograde pyelography
b) Intravenous pyelography
c) KUB X-ray
d) Barium Enema

Answer 1

Retrograde pyelography is the procedure used to inject iodine for visualizing the kidneys and ureters, especially to confirm IVU findings or when IVU is insufficient.

Step-by-step explanation:

The medical procedure that involves the injection of iodine using a ureteral catheter to visualize the kidneys and ureters is called retrograde pyelography. This procedure is often used to confirm findings from an intravenous urography (IVU) or when IVU results are insufficient. Retrograde pyelography provides detailed images of the urinary system, including the kidneys, ureters, and bladder, and can be crucial in diagnosing conditions like obstructions or stones in the kidneys or ureters.
