Except for the standard orchidopexy, staged operation and long-loop vas operation are the current method for treatment of the high undescended testis. There is, however, a relatively high rate of failure after these procedures. To improve the surgical results, we divised a staged orchidopexy with division of the spermatic vessels. To investigate the operative effects on the recovery of undescended testis, a high undescended testis was surgically created in 67 rats, then replace the testis into the scrotum 5 weeks after the preparation with or without division of the spermatic vessels. In cases with division of the spermatic vessels, the replacement of the testis was done either on the same day or 3 weeks after the operation. The bilateral testes were removed and measured and biopsied 5 weeks after final operation. The results of this experiment showed that the testis which was replaced into the scrotum 3 weeks after the division of the spermatic vessels showed better results than other experimental rats. This suggests that a staged orchidopexy with division of the vessels will improve the success rate over the more commonly used methods.
