Classification of Hypospadias

Hypospadia is classified by the location of the opening (meatus).

A Anterior - on inferior surface of glans penis.

B Coronal - in balanopenile furrow.

C Distal - on distal third of shaft.

D Penoscrotal - at base of shaft in front of scrotum.

E Scrotal - on scrotum or between the genital swellings.

F Perineal - behind scrotum or genital swellings.

Hypospadias most common penis abnormality (1 in 300) from a failure of male urogenital folds to fuse in various regions and resulting in a proximally displaced urethral meatus. The cause is unknown, but suggested to involve many factors either indivdually or in combination including: familial inheritance, low birth weight, assisted reproductive technology, advanced maternal age, paternal subfertility and endocrine-disrupting chemicals. Infants with hypospadias should not undergo circumcision.

Surgical Repair
