Egg retention and cloacal prolapse in a cockatiel (Nymphicus hollandicus): A clinical case report

Abstract

Egg retention refers to the condition in which an egg fails to pass through the oviduct within a specific period. Cloacal prolapse, on the other hand, is defined as the protrusion of cloacal tissues beyond the vent. Both conditions are influenced by various etiological factors. This case report presents a 2.5-year-old cockatiel (Nymphicus hollandicus) that was brought to the clinic with a complaint of tissue protruding from the vent for 24 hours and an inability to lay eggs. Physical examination revealed that the prolapsed tissue was the cloaca, and the egg was adhered to this tissue, preventing the egg-laying process. During the treatment, the cloacal region was lubricated with liquid vaseline, and slow, controlled manipulations were performed to remove the egg. Subsequently, the prolapsed tissue was cleaned and reduced using hemostatic agents. The patient was monitored during the postoperative period, and no recurrence of clinical signs was observed. This case highlights that egg retention and cloacal prolapse can be successfully managed with early intervention.
