Diagnosis and management of a patent urachus in a white rhinoceros calf (Ceratotherium Simum Simum)
A 10-day-old female southern white rhinoceros calf (Ceratotherium simum simum) was diagnosed with a patent urachus after urine was observed dribbling from the umbilicus. After being separated from its mother, the animal was sedated with i.m. butorphanol and anesthetized with isoflurane in oxygen for surgical correction of the patent urachus. Mild postoperative complications involved seroma formation and partial skin incision dehiscence, which necessitated three follow-up immobilizations for reevaluation and treatment of the surgical site. Histopathology did not reveal an infectious etiology as the cause for the complications or for the patent urachus. The etiology of the patent urachus in this animal remains undetermined. This report represents the first documented case of a patent urachus in a white rhinoceros.
