Epispadias
Definition
Epispadias is a rare congenital (present from birth) defect in which the opening of the urethra is in an abnormal location.
In boys with epispadias, the urethra generally opens on the top or side, rather than the tip, of the penis, though it is possible for the urethra to be open the entire length of the penis. In girls, the opening is usually between the clitoris and the labia but may be in the abdomen.
