An ectopic opening of the urethra on the ventral side of the urethra is called hypospadias. The hypospadias opening can occur anywhere between the perineum and the head of the penis. The distal end of the external urethral opening, the urethra and surrounding tissues are underdeveloped, forming a fibrous cord that pulls on the penis and bends it ventrally. It is a relatively common congenital malformation. Classification 1, penile head type The urethral orifice is located on the ventral side of the coronal sulcus, often slit-like, some can be complicated by urethral stricture, long dorsal foreskin, and no foreskin and tether on the ventral side. The head of the penis is exposed, smaller and slightly flat and wide, and bulbous in shape. The penis is bent ventrally, but to a lesser extent, and does not affect sexual intercourse and urination. 2.Penis type The urethral orifice is located at the ventral side of any part of the junction from the coronal groove to the penis scrotum, the urethral plate at the distal end of the urethral orifice is separated and does not form a tube, the penis bends ventrally, and the closer the urethral orifice is to the side the more serious the bending is, affecting intercourse and urination, and also affecting fertility. The shape of the head of the penis and foreskin is the same as that of hypospadias. The urethral orifice is located on the median line of the scrotum, which is often split like the female labia majora. Fibrous cords are formed at the distal end of the urethral opening. The penis is severely bent and requires squatting to urinate. The penis is short and flat, some resemble the female clitoris, and some testicles do not descend into the split scrotum or form a penile scrotal transposition. 4. Perineal type The urethral opening is located in the perineum, the scrotum is divided and underdeveloped, cryptorchidism may be combined, and the penis is small and curved, extremely similar to the fat clitoris. The entire genital development resembles female vulva, so that many parents mistake it for female. It requires squatting to urinate. Treatment 1. When the gender is determined to be male, a comprehensive treatment plan should be developed based on the type of hypospadias, combined with the presence or absence of female genital tract and testicular development. It should be carried out in stages, and the continuity of the treatment program should be maintained in each stage. 2.If the pediatric penis is poorly developed, it can be treated with 1 to 2 courses of chorionic gonadotropin before surgery, and then surgery can be performed after the penis has developed. 3.The purpose of surgery is to correct the downward curvature of the penis and restore the urethral opening to the position of the normal penile head or close to it, so that the pediatrician can stand to urinate and have the ability to reproduce as an adult. 4, tend to early treatment. The age of surgery used to favor school-age children, in fact, the size of the penis development of 1-year-old children is similar to that of 5-6-year-old children, and the reaction of young children after surgery is light, and early surgery can relieve the mental pressure of the family and the child, so it is appropriate to operate after the age of 1, at least before entering school or kindergarten.
