Ureteric Irregularity with Renal Artery Obstruction: A New Radiological Sign

Abstract

A case is described in which indentations of the upper ureter by anastomotic ureteric arteries on pyelographic examination constituted an indirect sign of renal artery occlusion. The blood supply of the ureter is considered and the part it plays in providing collateral channels in renal artery obstruction is discussed.
