What is cryptorchidism? How does cryptorchidism develop? Cryptorchidism is a common condition in children. It is also known as undescended testicle. During embryonic life, the testes are located at the level of the kidneys, and as the embryo develops the testes gradually descend into the scrotum. If there is an abnormality in the descent of the testicle, and the testicle fails to reach the scrotum by the time the child is born, it is called cryptorchidism. How is cryptorchidism treated? Hormone therapy can be used before the age of 1 year, but unfortunately most of them are not effective and most children with cryptorchidism need surgery. When is the best time to operate for cryptorchidism? The best age for surgery is between 1 and 2 years old. Some parents are pained by their children and delay the operation until 6-7 years old, which is very wrong, because the fertility of the testicle on that side has basically been lost by the age of 6-7 years old. The research result of foreign scholars suggests that at the age of 1 year, about 1/3 of the germ cells of cryptorchid testis have already disappeared, and some foreign scholars mention the age of cryptorchid testis surgery before 1 year. Can cryptorchid surgery be done laparoscopically? For cryptorchidism that has dropped below the inner ring, traditional surgery is more effective. For cryptorchidism where the testicle is above the inner ring, traditional surgery is slightly less effective and laparoscopic surgery is the best option. What are the advantages of laparoscopic cryptorchid surgery? 1.It is convenient and accurate to investigate the size, shape and location of testicle. For cases where ultrasound and CT cannot find the testicle, laparoscopic exploration is the best choice, laparoscopy can clearly see the size, shape and location of the testicle. 2.The length of spermatic vessels and vas deferens can be judged accurately, providing a reliable basis for choosing the operation. 3.It is convenient and reliable to free the spermatic vessels and vas deferens, and it can free the spermatic vessels and vas deferens in a wide range, which ensures that the spermatic vessels and vas deferens are fully free and the testicle can be put into the scrotum smoothly.
