[Antenatal diagnosis in cases of renal agenesis].

Renal agenesia was established by antenatal ultrasound diagnosis in 3 cases. The ultrasound image is characterized by the impossibility to visualize one or both fetal kidneys, oligohydramnios, lung hypoplasia and hypotrophy of the fetus. The possibilities for the earliest diagnosis as well as for interruption of pregnancy on account of the lethal outcome of the disease in the newborn are discussed.
