Pediatric cryptorchidism requires urology. Cryptorchidism is a congenital disorder in children, referring to incomplete testicular descent, testicular ectopic or testicular agenesis, and is treated accordingly according to the different clinical symptoms. The ideal age for effective fertility preservation is generally 1-2 years after birth. Testicular descent on its own after birth can occur within 6 months, after which the possibility decreases, and there is no longer any possibility of descent on its own after 1 year of age. 6-12 months is the best time to perform testicular descent fixation. According to the type of cryptorchidism, the following methods can be adopted. The first one is hormonal treatment, which refers to the injection of human chorionic gonadotropin, and generally has a relatively good therapeutic effect on retracted testis, but it is clinically controversial. The second one is surgical treatment, including open surgery or laparoscopic surgery. Depending on the location of the testicles, the corresponding surgical method can be chosen for the treatment to achieve the purpose of cryptorchidism eradication.
