Congenital abnormalities of the kidneys and the urinary tract are the most common sonographically identified malformations in the prenatal period. Obstructive uropathies account for the majority of cases. The aim of prenatal diagnosis and management is to detect those anomalies having impact on the prognosis of the affected child and requiring early postnatal evaluation or treatment to minimize adverse outcomes. In this paper, we summarize the embryology of kidneys and urinary tract, the normal sonographic appearance through- out pregnancy and the prenatal diagnosis of their congenital malformations.
