Pyometra in a sugar glider (Petaurus breviceps): surgical treatment and postoperative complications

抄録

A 7-year-old female sugar glider showed a well-defined, homogeneous, hypoechoic mass in the caudal abdominal cavity on ultrasound. Exploratory laparotomy revealed both uteri were severely dilated by viscous, purulent exudate. The patient underwent ovariohysterectomy with removal of bilateral vaginal canals. Antibiotic therapy was initiated postoperatively. Histopathological findings were consistent with suppurative metritis, leading to a clinical diagnosis of pyometra. Despite abscess formation in the uterine stump or central vaginal canal and bilateral renal pelvic/ureter dilations postoperatively, the sugar glider survived more than 270 days. Unfortunately, surgical and medical treatments performed in this case did not prove curative. The outcome of this case highlights the importance of further accumulation of cases to define more appropriate therapies for pyometra in sugar gliders.
