Prenatal diagnosis of hypospadias

Despite the fact that hypospadias is one of the most common congenital abnormalities of the genitalia, it is often missed on prenatal sonograms. In this paper, sonographic findings of six fetuses who were prospectively suspected to have hypospadias are presented. Of the six patients, isolated hypospadias was found in three, hypospadias with chordee in two, and isolated chordee in one. Additional malformations were present in four of the six fetuses. Sonographic findings of fetal hypospadias are described, and the embryology, anatomy, and associated abnormalities are discussed.
