An intravenous pyelogram is used to look for problems relating to the urinary tract. [5] These may include blockages or narrowing, such as due to kidney stones, cancer (such as renal cell carcinoma or transitional cell carcinoma), enlarged prostate glands, and anatomical variations, [5] such as a medullary sponge kidney.

The intravenous cholangiogram or IVC is a radiologic (x-ray) procedure that is used primarily to look at the larger bile ducts within the liver and the bile ducts outside the liver. The procedure can be used to locate gallstones within these bile ducts. IVC also can be used to identify other causes of obstruction to the flow of bile, for ...
Intravenous pyelogram, a radiological procedure used to visualize abnormalities of the urinary system, including the kidneys, ureters, and bladder; Inter-Varsity Press, the publishing wing of the United Kingdom-based Universities and Colleges Christian Fellowship
In order to assess these structures radiographically, a technique called an intravenous pyelogram was historically utilized, and today at many institutions CT urography is the technique of choice. [6]
In radiology and urology, a cystography (also known as cystogram) is a procedure used to visualise the urinary bladder.. Using a urinary catheter, radiocontrast is instilled in the bladder, and X-ray imaging is performed.
Regular X-rays often fail to show the cystine stones, however they can be visualized in the diagnostic procedure that is called intravenous pyelogram (IVP). Stones may show up on XR with a fuzzy gray appearance. They are radioopaque due to sulfur content, though more difficult to visualize than calcium oxalate stones. [citation needed]
The intravenous pyelogram can also be used to assess the presence of kidney stones. This test involves injecting a radiocontrast agent which is passed into the urinary system. X-ray images are then obtained every few minutes to determine if there is any obstruction to the contrast as it is excreted into the bladder.
Percutaneous nephrostomy is used in Whitaker test to differentiate recurrent obstruction or permanent dilatation after an operative surgery that corrects the cause of obstruction. This procedure is also used for antegrade pyelography to visualize the upper urinary tract system. [6]
