Abstract

Fetal bilateral renal agenesis is a lethal congenital anomaly characterized by bilateral pulmonary hypoplasia, deformities and death due to severe oligohydramnios. This syndrome is associated with malformations of genitourinary tract, cardiovascular system, vertebral bodies or imperforated anus in more than half of the affected individuals. An early and reliable prenatal diagnosis is extremely important because 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, empty renal fossae. But poor sonographic resolution of severe oligohydramnios makes it difficult to diagnose the disease. We present a case of bilateral renal agenesis diagnosed at the 18th weeks gestation by using Transvaginal Ultrasonography and Color Doppler.
