Diagnosis of Feline Pyometra Infections

Feline pyometra infections fall into two categories; open pyometra and closed pyometra.  When the condition is an open pyometra, the cervix is open.  Under these circumstances, pink or brown pus with an unpleasant odor drains out of the vagina.  In cases of a closed pyometra, the pus is unable to drain from the vagina, thus collecting in the uterus. 

Diagnosis of feline pyometra begins with a complete physical examination.  At this time the veterinarian will conduct a study of the cat’s current, as well as, previous medical history.  In some cases, an enlarged uterus will be apparent or a pus discharge from the vagina can be seen.  As part of the evaluation, a routine blood workup will be done to check for an elevation in the white blood cell count.  The laboratory results will supply the veterinarian with additional much needed diagnostic information. 

Radiographs may also be used as an additional diagnostic tool.  The employment of ultrasound equipment if available can be immeasurable in diagnosing a cat with a pyometra infection.  During the physical evaluation, the veterinarian may notice a pus discharge from the vagina.
