Angiographic patterns of posttraumatic renal scarring.
Evaluation of 19 patients with a history of renal trauma revealed three angiographic features helper in the diagnosis of posttraumatic renal scarring: (1) a cup-shaped renal contour defect characterized by smooth margins, infolding of the renal cortex, and extension of the calyces to the edge of the defect; (2) occlusion of an extra- or intrarenal artery associated with a distal avascular zone of infarction; and (3) a grossly heterogeneous nephrogram characterized by scattered islands of renal tissue separated by broad or narrow avascular scars. Limited pathologic correlation suggests that the cup-shaped contour defect reflects subcapsular hemorrhage and that the mottled, heterogeneous nephrogram reflects a shattered kidney.
