Plastic surgery for hypospadias has a history of 100 years, and there are more than 200 surgical methods. Each method has its own advantages and disadvantages, and its surgical methods can be summarized into two categories: one-stage plastic surgery and staged plastic surgery: one-stage plastic surgery is to correct penile kyphosis and reconstruct urethra in one operation; Staged operation is to correct the deformity of penis curvature, do a good job of foreskin skin transfer, and then reconstruct urethra after 6 ~ 12 months. The choice of operation method should be flexibly mastered according to the type of hypospadias, the specific situation of patients and the experience and habits of operators. Generally speaking, penile hypospadias can be operated in one stage, scrotal hypospadias and perineal hypospadias can be operated in one stage or by stages according to the situation. Opinions on the age of operation are still not uniform, and most scholars believe that all treatments should be completed before school age.
