Rectal prolapse secondary to a urachal abscess in an alpaca cria.

A five-month-old alpaca cria presented with a history of abdominal pain, dysuria, and a recurring rectal prolapse. An ultrasonographic examination indicated a urachal abscess attached to the urinary bladder. The abscess was removed surgically, and the patient had an adequate recovery after the procedure and ancillary treatment. This case report highlights secondary complications that could arise following an infection of the urachus in new-world camelids. Key clinical message: Urachal abscess should be considered as a differential diagnosis in juvenile new-world camelids with rectal prolapse, tenesmus, or dysuria.
