Three cases of renal agenesis are presented, representing the spectrum of abnormality seen in utero. Severe oligohydramnios was seen in all three cases. In two cases ultrasound demonstrated fetal paraspinal structures resembling kidneys, while in the third no renal shapes were identified. The urinary bladder could not be imaged in any of the cases. Autopsy findings demonstrated that the reniform structures represented only fetal adrenal glands of varying sizes. It is suggested that the examination of the renal tract in severe oligohydramnios should be directed toward the fetal urinary bladder, because the identification of reniform outlines can be misleading.
本文报告了三例肾缺如病例，代表了子宫内所见的异常范围。所有三例均出现严重羊水过少。其中两例超声显示胎儿脊柱旁结构类似肾脏，而第三例未发现肾脏形态。所有病例均无法对膀胱进行成像。尸检结果表明，肾形结构仅代表不同大小的胎儿肾上腺。建议在严重羊水过少时对尿路进行检查时应针对胎儿膀胱，因为肾形轮廓的识别可能会产生误导。
