title: Isolated single umbilical artery--the case for routine renal screening.
abstract: To determine the incidence of silent renal anomalies in infants with isolated single umbilical artery (SUA), all infants with SUA and without other obvious congenital anomalies, identified over a six year period, were screened using renal ultrasonography. Over 35,000 placentas were examined. An isolated single umbilical artery was identified in 112 (0.32%). Nineteen infants had abnormal renal imaging. Eight of 112 (7.1%) had significant persisting abnormalities. Vesicoureteric reflux was found in five infants (4.5%). It is recommended that renal ultrasonography be performed for all infants with isolated SUA.
