Ureteral Changes in Polyarteritis Nodosa as Seen During Excretory Urography

Abstract

The conventional excretory urogram may provide valuable information in the diagnosis of polyarteritis nodosa. A finding of imprints on the ureteral wall or a nodular appearance of the ureter simulating a string of pearls would seem to be pathognomonic for this disorder. Two cases with these manifestations are presented and the differential diagnosis is discussed.
