This is a very rare malformation (incidence 1:30,000 male infants) in which the urethra opens on the dorsal surface of the penis. The embryological basis of this anomaly is unclear. It has been proposed that epispadias is caused by a caudal shift of the paired primordia of the genital tubercle, forcing the urethral groove to form on the dorsal surface of the penis. The epispadias is mostly associated1 with exstrophy of the urinary bladder.
