Laparoscopic cryptorchidectomy in dogs --report of 15 cases.

The study aimed at determining the usability of laparoscopic cryptorchidectomy in treating cases of simple cryptorchidism and neoplastic testes in dogs. The presence of one or both testes inside the peritoneal cavity was confirmed in this study by an ultrasonographic examination employing the use of a 6.5 MHz convex head. The surgeries were conducted on a group of 15 dogs. In 12 subjects a one-sided cryptorchidism was found, 9 of which had right-sided cryptorchidism. In 3 dogs, both-sided cryptorchidism was observed. In 3 cases, an increase in the size of the abdominal testes with the symptoms of hyperestrogenism and feminisation raised a suspicion of neoplastic changes (SCT) taking place, which was confirmed by a histopathological examination. A laparoscopic cryptorchidectomy with intracorporal ligation was performed in all the subjects. The spermatic cord and ductus deferens were occluded with a ligature of an absorbable material, and a manually applied knot.
