Microvascular autotransplantation of the intra-abdominal testis

The operative management of intra-abdominal testes is controversial, largely because there is no method of orchiopexy that can reliably produce good results. We report our results on the use of microvascular autotransplantation of intra-abdominal testes. We performed 12 autotransplants in 10 boys ranging in age from 10 months to 14 years (median age 30 months). In each instance the testis had been localized previously by laparoscopy or it was known to be inta-abdominal and was believed to be grossly normal in appearance. The vascular anastomoses of the spermatic to the inferior epigastric vessels were performed by an experienced microvascular surgeon using 10-zero nylon suture and 40 times magnification. Biopsies were taken at operation in 9 patients. Follow-up of 6 to 30 months is available in 7 patients and all 8 testes are palpably normal and in good scrotal position. This approach is feasible even in small children and the results seem to be superior to the expected results reported with division of the spermatic vessels.
