Abstract:
Purpose To investigate the prenatal ultrasonic features of fetal hypospadias and to compare the diagnostic accuracy.Materials and Methods The clinical data of 28 patients with suspected or confirmed hypospadias were retrospectively analyzed.The prenatal ultrasonic features,missed diagnosis and misdiagnosis of the patients were analyzed,and the diagnostic accuracy of different ultrasonic features for hypospadias was compared.Results In 28 cases,21 cases of hypospadias were confirmed by examination after birth or induced abortion with 2 cases of missed diagnosis by ultrasound,and 7 cases of non hypospadias were misdiagnosed by prenatal ultrasound.The diagnostic accuracy rate of 2D ultrasound was 67.9％ (19/28),and that of 3D ultrasound combined with 2D ultrasound was 92.9％ (13/14).The diagnostic accuracy rates of ultrasonic features such as abnormal urinary jet,abnormal urethra,tulip sign,abnormal penis tip,scrotum separation with or without penoscrotal transposition and short penis were 100.0％ (6/6),92.9％ (13/14),88.2％ (15/17),83.3％ (5/6),25.0％ (1/4) and 33.3％ (1/3),respectively.Conclusion The ultrasonic features including abnormal urinary jet,abnormal urethra,tulip sign and abnormal penis tip have great value for prenatal diagnosis of fetal hypospadias.3D ultrasound is more intuitive than 2D ultrasound and provides more details.Comprehensive analysis of all ultrasonic features is helpful for prenatal diagnosis.
