Management of glandular hypospadias with congenital urethral atresia in a Friesian colt

Summary A 5‐day‐old Friesian colt was presented to the University of Missouri Veterinary Health Center with lethargy, progressive abdominal distension and failure to urinate. Upon examination, the colt appeared dehydrated with marked abdominal distension and dull mentation. Bloodwork revealed severe azotaemia, electrolyte derangements and an inflammatory leucogram. Transabdominal ultrasound revealed a large volume of free peritoneal fluid and evidence of a ruptured bladder. The uroperitoneum was confirmed via abdominocentesis. The colt was stabilised, and an exploratory laparotomy was performed. A ruptured bladder and concurrent membranous obstruction at the level of the penile urethra, consistent with congenital urethral atresia‐like abnormality and hypospadias, were identified. The bladder tear was repaired in routine fashion, and a functional urethral opening was created. Postoperatively, a urinary catheter was maintained for 4 days, and the colt received intravenous antibiotics, anti‐inflammatory medications and gastroprotectants. Azotaemia and electrolyte imbalances progressively improved. The colt is reportedly doing well after discharge from the hospital.
