Penis/hemipenile amputation

Contributor(s) :


Introduction

  • Treatment option of choice for recurrent, infected, or necrotic prolapses of the copulatory organ in reptiles. The reptile penis and hemipenes do not contain a urethra and are therefore not involved in urination.
  • The patient must be stabilized pre-operatively and underlying cause of prolapse investigated and resolved Cloacal organ prolapse.

Uses

Advantages

  • Technically easy procedure requiring a short general anesthetic.

Disadvantages

  • Requires a general anesthetic.
  • Excludes animals from breeding programs. Animals with hemipenes such as snakes and lizards will still be able to reproduce.

Technical problems

  • Necrosis of the prolapsed tissue may be extensive in chronic cases.
  • Underlying cause of prolapse needs to be corrected.
  • Anesthesia challenges in reptiles; these species often require specialized equipment listed below and may not always respond to medications in the same predicted manner as mammals.

Alternative techniques

  • For simple prolapses of healthy organs simple replacement of the prolapsed organ should be attempted.
  • Underlying cause of prolapse must be resolved Cloaca / colon manual replacement.

Time required

Preparation

  • 5 min.

Procedure

  • 5-10 min.

Decision taking

Criteria for choosing test

  • Necrotic or recurrent prolapse of the copulatory organ non-responsive to medical treatment.

Risk assessment

  • The patient will require a general anesthetic, all patients should be stabilized pre-operatively.
  • Where a unilateral hemipenis prolapse is present, the risk of contralateral prolapse occurring needs to be discussed with the owner.
