Epispadia

Explanation

Hypospadias is a congenital defect, primarily of males, in which the urethra opens on the underside (vent rum) of the penis. Epispadias (also called bladder exstrophy) is a congenital defect of males in which the urethra opens on the upper surface (dorsum) of the penis.Hypospadias is a congenital abnormality of the penis which occurs in 3/1,000 male infants Hypospadias is characterized bya ventral urethral meatusa hooded prepucechordee (ventral curvature of the penis) in more severe formsthe urethral meatus may open more proximally in the more severe variants. However, 75% of the openings are distally located.Hypospadias most commonly occurs as an isolated disorder. Associated urological abnormalities may be seen in up to 40% of infants, of this cryptorchidism is the most frequent (10%). Corrective surgery is performed before 2 years of age. It is essential that the child is not circumcised prior to the surgery as the foreskin may be used in the corrective procedure. In boys with the very distal disease, no treatment may be needed.
