Laparoscopy: cryptorchidectomy

ffelis

Synonym(s): Key-hole cryptorchidectomy, Laparoscopic cryptorchidectomy


Introduction

  • Cryptochidism is the failure of one or both testicles to descend down into the scrotum. The retained testicle(s) can be inguinal, pre-scrotal or abdominal. Incidence in dogs between 1.2-12.9% and cats 1.3-3.8%. Monorchidism and anorchism are rare.
  • Abdominally retained testicles are up to 13.6 times more likely to develop testicular neoplasia and at higher risk of developing torsion than a descended testicle.
  • Removal of the non-distended abdominal testicle can be performed via open or minimal invasive (laparoscopic) surgery.
  • The patient should always be fully castrated or as a minimum a vasectomy should be performed on the remaining testicle. This can be done laparoscopically using a vessel sealing device.

Uses

  • Minimal invasive abdominally retained testes removal.

Advantages

  • Rapid recover.
  • Improved visualization and magnification.
  • Reduces risk of urethral avulsion (and accidental prostatectomy).
