Comparison of arteriography, venography, and pyelography in experimental renal trauma.

Experimentally produced renal injuries are shown by arteriography, venography, and retrograde pyelography using geometric magnification techniques. Arteriography is the most satisfactory modality examined. Venography is technically more difficult and generally less sensitive than arteriography, although extravasation of contrast material was shown with equal frequency. Retrograde pyelography is inferior to arteriography and correlates closely with the venographic findings.
