[Cryptorchism and surgery]

Many different anatomical situations are observed by pediatric surgeons during the surgical procedure for cryptorchidism at any age. The authors propose an easy anatomical classification: type I seems to be a small trouble of the process of migration and to be more a disturbed fixation. Type III results from a big disturbed wolfian duct process. Type II is intermediary. A series of 102 cryptorchidism operated upon at the Pediatric Surgical depart. Children's Hospital Paris, were studied according to this classification and collorated with histopathological study. The correlation is significative. The authors suggest that this protocol of surgical description could be agreed by a lot of Pediatric surgeons, whatever be the age of patient at operation, in the purpose to allow a longitudinal study from initial anatomical disorders to spermogram and at last to bring a response to the unanswered question: what, when and how, a cryptorchidism has to be cured.
