Types of Hypospadias

Hypospadias is one of the most frequent male congenital malformations and may be part of the testicular dysgenesis syndrome, It occures 1-2 of 100 boys. Hypospadias is a birth defect found in boys in which the urinary tract opening is not at the tip of the penis. Bending of the penis on erection may be associated and is as chordee.

This picture shows Proximal shaft hypospadias . Note the deficient ventral foreskin, blind urethral pit at the glanular level, and lighter pigmented urethral plate extending to the true meatus at the proximal shaft level.

The location of the urethral meatus was described if visible, and hypospadias was graded as glandular, coronal, penile, penoscrotal, scrotal, or perineal according to the anatomical position

Types of hypospadias classified by the anatomical position of the urethral meatus. 1, Glandular; 2, coronal; 3, penile; 4, penoscrotal; 5, scrotal; 6, perineal.

On examination :A dorsal hood of foreskin and glanular groove are evident, but, upon closer inspection, the prepuce is incomplete ventrally and the urethral meatus is noted in a proximally ectopic position. Rarely, the foreskin may be complete, and the hypospadias is revealed at the time of circumcision. If hypospadias is encountered during neonatal circumcision, after the dorsal slit has been performed, the procedure should be halted, and the patient should be referred for urologic evaluation.
 The most simple classification of Hypospadias is mild, moderate and severe, which can also be called first, second and third degrees of severity. This classification system is based on the location of the external opening for urine and semen (the urethral meatus). In mild or first degree hypospadias, the opening is on the underside of the head of the penis or where the head and the shaft meet. This accounts for about 80% of the cases of hypospadias.

Moderate or second degree hypospadias (15%) occurs when the hole is actually on the shaft of the penis, somewhere between the junction of head and shaft, and the lower part of the shaft. Severe or third degree hypospadias occurs when the hole is located on the lower part of the shaft just in front of the testicles or is located behind the testicles, between them and the anus.
