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.
为了确定孤立性单脐动脉（SUA）婴儿中无症状性肾脏异常的发生率，对6年内确诊的所有患有SUA且无其他明显先天性异常的婴儿进行了肾脏超声检查。共检查了超过35000个胎盘。发现112例（0.32%）存在孤立性单脐动脉。19例婴儿肾脏成像异常。112例中的8例（7.1%）存在持续的显著异常。5例婴儿（4.5%）发现膀胱输尿管反流。建议对所有患有孤立性SUA的婴儿进行肾脏超声检查。
