| Problems within the urinary tract are relatively well known in foals and include, among others, persistent urachus. In most cases, treatment is carried out in the stable and does not require hospitalization of the foal. In the case described, the problem of persistent urachus was accompanied by uroperitoneum and deteriorating general condition, which prompted the attending veterinarian to refer the patient for hospital treatment. After the animal was admitted to the clinic, routine procedures were implemented – antibiotic therapy, antiinflammatory treatment, a catheter into the urinary bladder and a drain were inserted into the abdominal cavity, and intensive fluid therapy was implemented to correct electrolyte imbalances. An abdominal ultrasound was performed, which confirmed the presence of a large amount of fluid in the abdominal cavity, but did not reveal the site of the bladder wall damage. During hospitalization and stabilization of the patient, a very rare complication occurred – a fragment of the omental prolapsed through the open urachus, which allowed a diagnosis of urachus rupture to be made. The omentum was immediately ligated and removed, and the navel was secured with a dressing. After stabilising the electrolyte levels in the blood, surgery was performed under general anaesthesia, during which the persistent urachus was removed along with the apex of the bladder. The foal’s recovery and postoperative period were proceeded without complications. |
