Acute pyelonephritis most often shows no radiographic abnormalities with excretory urography. There are, however, findings which in the right clinical setting are consistent with acute pyelonephritis (Fig. 1). The kidney is swollen and enlarged with thin and spidery calyces when compared to the opposite side. There may be focal or generalized increased prominence of contrast in the pyramids, likely due to stasis in these areas.
