Surgery Overview

CASTRATION/CRYPTORCHID

GENERAL INFORMATION
 

  • Cryptorchid testes are usually smaller, soft and misshapen compared to the descended testicles.
  • Cryptorchid testes may be found in the inguinal area or the abdominal cavity.
  • If testes are not palpable they must be located by abdominal exploration.
  • Cryptorchidism is believed to be a sex-linked autosomal recessive trait in dogs. For this reason, bilateral castration for cryptorchid dogs is recommended.
  • There is little chance that further testicular descent will occur after two months. Retained testicles are predisposed to neoplasia and thus should always be removed.
  • The risk of ligature slippage is minimized with open techniques.

 
 

MOST COMMON COMPLICATIONS AND DIFFICULTY
 

  • Hemorrhage and swelling are the most common complications.
  • Removal of the tunics and careful ligation of the vessels will avoid this complication.
  • The prostate can be mistaken for a retained testicle.
  • Locating retained testes within the abdomen may be difficult.

Ligate the ductus deferens and vascular cord individually and then encircle both with a proximal circumferential ligature.

"EXPERTS' ADVICE"
 

  • Strip the tunic up and down with a gauze sponge to remove all fat and fascia tissue. This will allow improved ligature security.
  • For retained testicles, follow the ductus deferens from the trigone of the bladder, or the spermatic vessels from the caudal pole of the kidney to locate the testicle.
  • If one testicle is in the scrotum, push it forward to see which side of the prepuce it enters. The other side is the cryptorchid testicle.

 
 

SH needles work nicely to perform closed castration using transfixation ligature with closed castration. Skin suture should be avoided in cats. In dogs, an intradermal closure of the prescrotal incision should be performed.
