Bilateral renal agenesis is a lethal congenital anomaly. It appears to be transmitted in a polygenic pattern. The prenatal ultrasound findings consist of severe oligohydramnios, absence of the fetal bladder, and failure to identify fetal kidneys. Twin gestations with renal agenesis have been described in the paediatric literature. We detail a case of a patient with two prior affected pregnancies with bilateral renal agenesis. Her latest pregnancy was diagnosed prenatally, with one fetus with bilateral and the other fetus with unilateral renal agenesis. The ultrasound findings should be differentiated from the stuck twin phenomenon.
双侧肾缺如是一种致命的先天性异常。它似乎以多基因模式遗传。产前超声检查结果包括严重羊水过少、胎儿膀胱缺如以及未能识别出胎儿肾脏。儿科文献中已描述过伴有肾缺如的双胎妊娠。我们详细介绍了一位患者的病例，她之前有两次妊娠均出现双侧肾缺如。她最近一次妊娠在产前被诊断出来，一个胎儿为双侧肾缺如，另一个胎儿为单侧肾缺如。超声检查结果应与联体双胎现象相鉴别。
