Pyometra

Pyometra is common in old intact bitches and certain dog and cat breeds. Animals with open pyometras usually have milder clinical signs. Closed pyometra can be a surgical emergency. Treatment is by ovariohysterectomy: the abdominal incision should be long so the uterus can be carefully lifted from the abdomen without tearing it. Ligations are similar to those of a large dog spay; uterine clamps must be used cautiously because the uterus may be friable. If a stump pyometra is present, the abdomen should be explored for ovarian remnants. Animals with pyometra may have concurrent urinary tract infections; urine for culture can be obtained by cystocentesis during surgery.
