Microvascular surgical orchiopexy in the treatment of high-lying undescended testes

Extensive laboratory experiments in animals have led us to believe that autotransplantation of the testis in the human is feasible. To date, nine of our patients (aged 4-13 years) with undescended intra-abdominal testes have undergone autotransplantation. Using a microvascular surgical technique to anastomose the testicular vessels to the inferior epigastric vessels, it has been possible to place the testis in a scrotal position in every case. No postoperative complications have been noted. Follow-up varied from 9 to 18 months and no atrophy of the testis was observed in this period. Doppler investigations on all of the transplanted testes continue to demonstrate good arterial flow. The aim of surgery on the undescended testis is not only to increase the chances of fertility and to diminish the possibility of malignant transformation but also, more importantly perhaps, to prevent possible abnormal psychosexual development in the child.
