Objective Combined with 2D and 3D sonographic appearance of fetal hypospadias, to investigate the application of ultrasonograph in prenatal diagnosis of fetal hypospadias. Methods Retrospective analyzing sonogram characteristic of 5 cases who were diagnosed in our hospital as fetal hypospadias from November 2012 to March 2014, and analyzed the database with the follow-up results. Results 4 fetuses showed "tulip flower syndrome" which was induced by small penis and separated scrotum, 1 fetus showed small penis. There are 3 cases of scrotal type of hypospadias, 1 case of penile type of hypospadias, 1 case of scrotal- penile type of hypospadias in postpartum follow-up. One fetus with single umbilical artery and fetal ventricular septal defect, one fetus with persistent right umbilical vein, two fetuses were not detected obvious fetal organ abnormity, a pregnant woman with pregnancy induced hypertension. Conclusions prenatal ultrasound is the preferred method for detection and diagnosis of fetal hypospadias, three-dimensional ultrasonography can play a more direct effect in the diagnosis of fetal hypospadias.
