Notching of the ureter and renal pelvis in children
RH Cleveland,
KE Fellows,
and
RL Lebowitz
The excretory urograms of 14 children with ureteral notching were reviewed. In 10 of 14 cases the vascular impressions on the ureters were due to either venous obstruction and dilated collaterals or to dilated noncollateral veins. In two cases the notching was associated with arterial collaterals in renal ischemia and in two with dilated lymphatic channels. The implications of notching in children and the differences and similarities of this urographic sign between children and adults are discussed.
