In pyometra, what is the definitive surgical treatment?

• A. Medical management only
• B. Antibiotics alone
• C. Hormonal therapy
• D. Ovariohysterectomy

Answer: (D)

Pyometra is driven by the uterus being the source of infection and hormonal changes; removing that source is the only way to cure and prevent recurrence. An approach that relies on antibiotics alone doesn’t eradicate infected tissue and leaves the uterus at risk for ongoing infection, rupture, or sepsis. Hormonal therapy might briefly modify uterine conditions or drainage but does not remove the infected tissue and carries risks; it is not a definitive solution for pyometra. Surgically removing the ovaries and uterus eliminates both the source of the infection and the hormonal drives behind the condition, offering the best chance for a full, lasting recovery, especially when the animal is a non-breeding patient and stable enough for surgery. In cases where stabilization is a concern, initial medical management can be used to support the patient, but the definitive treatment remains ovariohysterectomy.
