Prenatal Hydronephrosis Caused by Aberrant Renal Vessels: A Follow-Up Challenge

Abstract

With routine use of obstetric ultrasonography, fetal low-grade hydronephrosis is commonly detected, but may resolve spontaneously after birth. Two cases are presented to illustrate that in some cases such findings can express intermittent hydronephrosis caused by aberrant renal vessels. Renal deterioration later in childhood may be a consequence.
