A 4 year old castrated male Pygmy goat presented to the Cornell University Farm Animal Hospital with a history of lethargy and dribbling urine. On presentation, the patient was alert but quiet and painful on abdominal palpation. Urinary obstruction was confirmed via abdominal ultrasound. Urethral process amputation and tube cystostomy were performed, but the patient remained uncomfortable and began to strain during the week following surgery despite multimodal pain management. Contrast cystourethrography revealed numerous radiopaque calculi obstructing the urethra at the level of the sigmoid flexure; no bladder or urethral rupture was evident. The patient was anesthetized and a perineal urethrostomy with penile amputation was performed. Analysis of the calculi obtained at the time of surgery revealed 100% calcium carbonate. The patient was discharged to the care of his owners with a diet plan formulated to achieve weight loss and decrease the risk of recurrent urolithiasis.
