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.
尽管尿道下裂是最常见的先天性生殖器异常之一，但在产前超声检查中常常被漏诊。本文介绍了六例前瞻性怀疑患有尿道下裂胎儿的超声检查结果。六例患者中，三例为单纯尿道下裂，两例为伴有阴茎下弯的尿道下裂，一例为单纯阴茎下弯。六例胎儿中有四例存在其他畸形。描述了胎儿尿道下裂的超声检查结果，并讨论了其胚胎学、解剖学及相关异常情况。
