Abstract
hypospadias is a congenital disorder wherein the urethral meatus fails to open at the tip of the glans penis and may appear anywhere between the ventral glans and the perineum.
The incidence of hypospadias is approximately 1 in 300 live male births, and the majority of these defects are in the distal shaft of the penis. Hypospadias results from incomplete development of the embryonic urethral tube to the distal glans.
The degree of hypospadiac severity is best classified by the position of the urethral meatus into distal, middle and proximal. Distal defects usually include glanular, coronal and subcoronal hypospadias. Middle and proximal hypospadiac defects are often associated with significant chordee (bending on erection). Torsion, or twisting of the penis, usually to the left, is common.
