When a boy urinates not forward, but downward or upward, or when the urine line is too thin, it is a urinary abnormality. Hypospadias is a type of urinary abnormality that should be taken seriously by parents. Hypospadias, or abnormal urethral opening, is a common congenital malformation of penile development in children, with an incidence of about 8 per 1,000 in male newborns. In addition to affecting the normal life of the child, it can also cause great psychological trauma to him. The development of hypospadias is the result of multiple factors, related to the level of estrogen and androgen during the mother’s pregnancy, hereditary, with a certain tendency to develop in families, and also related to environmental pollution. There are three main manifestations of hypospadias: ectopic urethra, recurved penis, and prepuce in the form of a cap on the dorsal side of the penis, which are not difficult to diagnose at first sight. The urethral opening of children with hypospadias is at different locations from the ventral side of the penis to the perineum of the scrotum. Although children with urethral opening in front (i.e. penile head type) do not prevent standing to urinate, the penis shape is more abnormal and the urine line is downward sloping; those with urethral opening in the penis stem, scrotum or perineum not only need to squat to urinate, but also can affect the normal development of the penis due to the associated hypospadias deformity, which is more serious when the penis is erect at puberty. And can be accompanied by pain and sexual life difficulties. Parents should pay more attention to their children when they are young, and strive for early detection and early treatment. Once the diagnosis of hypospadias is confirmed, surgery should be given at an appropriate time to correct the downward curvature of the penis, so that the urethral opening is as close to the normal position as possible, so that the child can stand to urinate, and to ensure the ability to have a normal married life as an adult. The surgery should be performed in a hospital with a specialty in pediatric surgery. In recent years, the surgical treatment of this disease has made great progress, and the staged surgery used in the past has been replaced by a one-stage operation, which not only greatly reduces the pain of the child, but also puts more emphasis on the appearance and function of the penis as close to normal as possible. The pediatric surgery motor of the Guangzhou Huadu District Maternal and Child Health Hospital. Regarding the age of surgery, it is now generally accepted that it should be done before school age, or even earlier to reduce the psychological trauma of the child. Generally speaking, children around the age of half a year can reach the basic conditions to complete surgical repair. In cases of short-segment hypospadias and without hypospadias, the surgery can also be done earlier. In cases of combined penile dysplasia, which is often associated with endocrine defects, appropriate tests and hormone therapy should be performed before surgery is performed after the penis has enlarged. Generally speaking, most children with hypospadias can achieve satisfactory results after surgical correction, and as long as the testicles function normally, they will be able to have children in the future.
