Cryptorchidism. Current concepts.

Cryptorchidism is the most common genitourinary disorder of childhood. Even though its incidence has changed only slightly over the years, the number of operations for cryptorchid testes has tripled. Better understanding of the natural history of cryptorchidism, as well as changes that occur in testicular histology both in the cryptorchid and the contralateral descended testis very early in life, are the cause. This experience has led us to advocate early orchiopexy as the optimum means of treatment.
