Staged orchidopexy with division of spermatic vessels: an experimental study

To improve the therapeutic results of high undescended testis, we conducted experiments with division of spermatic vessels and replacement of the testis into the scrotum after preparation of undescended testis in rats. The results of this experiment show that 1) testis in which the vessels were divided at the inguinal level showed distinct degeneration from infarction one month postoperatively, 2) testis in which the vessels were divided at the abdominal level appeared normal, and 3) in the rats with preparation of undescended testis, bringing down the testis at some interval after division produces better results as to the recovery of the testis.
