Uroperitoneum Secondary to the Rupture of the Urinary Bladder in a Thoroughbred Foal

A 13-day-old Thoroughbred female foal weighing 59 kg was referred to the Jeju National University Equine Hospital with clinical signs including depression, labored breathing, tachycardia, anorexia, and marked distended abdomen. Uroperitoneum secondary to a rupture of the urinary bladder was diagnosed based on the history, clinical signs, and ultrasound imaging. An emergency laparotomy for cystorrhaphy under inhalation anesthesia was performed, and the patient recovered uneventfully. A course of extensive supportive therapy with systemic antibiotics after surgery was carried out. The foal fully recovered and was discharged after 14 days of hospitalization. The follow-up after seven months revealed the patient to be clinically healthy. This report describes a case of uroperitoneum secondary to the rupture of the urinary bladder in a Thoroughbred foal, along with the clinical outcomes of surgical repair and intensive treatment in detail.
