[The autotransplantation of undescended testes]

A procedure for microsurgical autotransplantation of the undescended testis was proposed, which was different from the well-known ones by the fact that following microvascular anastomoses made between the testicular and lower epigastric vessels, the testis was brought to the scrotum in the clinostatic position through the medial inguinal fossa with prior mobilization of the deferent duct up to the level of the epididymal tail, by straightening the epididymal differential loop. The procedure allows one to provide a relative stretching of the deferent duct at a length equal to the longitudinal axis of the testis, thus achieving the optimal level of scrotal testicular position with initially high retention and a short deferent duct. Biopsies and clinical trials make it possible to recommend the procedure in the surgery of complicated cryptorchidism.
