title: Sonographic diagnosis of congenital megalourethra at 13 weeks of gestation.
abstract: Congenital megalourethra is a rare disorder characterized by the congenital absence of the corpus spongiosum and/or corpus cavernosum, leading to dilatation of the urethra. We present a case of congenital megalourethra diagnosed by ultrasound examination at 13 weeks of gestation. Transabdominal and transvaginal sonography showed gross megacystis, bilateral hydronephrosis and a cystic dilatation of the penis. Transabdominal needle embryoscopy confirmed a balloon dilatation of the fetal penis. The pregnancy was terminated by suction curettage.
