Differential Diagnostic Importance of Retrograde Phlebography in Cases of Unusual Ectasia and Renal Pelvic Deformity

Abstract

Retrograde renal phlebography is important in the differential diagnosis when carcinoma of the renal pelvis is suspected. Vessel cut-offs, differences in contrast density, variations in vessel caliber, and irregular identations of the vessel wall can be seen with this technique. This seems to be the only method of demonstrating varicositites of the renal veins.
