T/F: It is okay to shave the scrotum
FALSE
WHat is the distance of draping from the midline?
2-3 cm from midline

TRUE- only incised
What is the sx approach for a cryptorchid patient?
Inguinal or abdominal
What are the differences between closed and open castration?
Closed: doesn’t penetrate PVT, increases risk of non-secure ligature, decrease risk of scrotal hematoma, decrease post-op swelling and quicker
Open: penetrates PVT, decrease risk of ligature slipping, decrease risk of abdominal hemorrhage, longer
How far should the proximal clamp be placed from the body wall?
1-2 cm
What suture should be used for ligation?
2-0 monofilament absorbable
What suture should be used for the closure?
3-0 monofilament absorbable
T/F: You shouldn’t strip the spermatic fascia in an open castration
TRUE
What are four common complications of a castration procedure?
Scrotal hematoma
Infection
Hemorrhage
Swelling/bruising
What is anorchism?
Absence of both testicles
What is monorchism?
Absence of one testicle
What is cryptorchism?
One or both testicles not descended into scrotum- developmental problem of gubernaculum
When do most testicles descend?
30-40 days- considered cryptorchid if not descended by 6 months
What are the three location classifications of a cryptorichidism?
Abdominal, inguinal or pre-scrotal
What type of cryptorchidism is more common in dogs?
Unilateral- small dogs prone to this
HERITABLE- DON’T BREED
What are functional characteristics of a cryptorchid testicle?
Sterile because the warm environment destroys sperm
Suppresses spermatogenesis in normal testicle
Predisposed to neoplasia
Predisposed to torsion
What are other abnormalities that are seen in dogs vs. cats with cryptorchidism?
Dogs: hip dysplasia, patellar luxation, penile or preputial defects, umbilical hernia
Felines: patellar luxation, short/kinked tail, tarsal deformities, eyelid agenesis
What are some complications of feline castration?
Funiculitis
Scrotal hematoma
scrotal abscess
priapism
