A Case of Bilateral Renal Agenesis Diagnosed by Prenatal Ultrasonography / 대한산부인과학회잡지

ABSTRACT

Fetal bilateral renal agenesis is a lethal congenital anomaly. An early and reliable prenatal diagnosis is extremely important as it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, and the empty renal fossae. However, severe oligohydramnios makes it difficult to diagnose the disease because of poor sonographic resolution. We present a case of fetal bilateral renal agenesis diagnosed by ultrasonography after amnioinfusion at 19 weeks gestation.
