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). But with IVP, the dye is injected into a vein instead of the ureter.

What's the contra indication of retrograde pyelography?
