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
Depending on the class of hypospadias there are a number of different surgical repair techniques including: orthoplasty or penile straightening, urethroplasty, meatoplasty and glanuloplasty, scrotoplasty and skin coverage.
