Microsurgical technique and results of testicular autotransplantation in children--essential venous anastomosis.

For more than 10 years autotransplantation of the testis has proved to be a surgical technique with a definitive place in the therapy of high-abdominal cryptorchidism. It is a procedure to be employed in situations where appropriate mobilization yields an ineffective orchiopexy. In a review of 245 cases in the literature a success rate of 87% is reported. The problems of diagnostic procedures like ultrasonography, magnetic resonance imaging and laparoscopy and of operative technique are described in detail. The relevance of venous anastomosis is discussed and stressed, and the results of 8 own cases are presented.
