Uterine prolapse and eversion is a relatively uncommon gynecological disorder of dogs characterized by expulsion of part or all of the uterus.
Prolapse of the uterus invariably occurs immediately after or within several hours of parturition, when the cervix is open and the uterus lacks tone.
In rare cases, herniation of the uterine body, urinary bladder, and distal aspect of the colon may occur, resulting in a medical emergency.
This condition is relatively easy to diagnose on visual inspection, although differentiation from vaginal prolapse is important. In dogs with dystocia, remnant fetuses may still be present in non prolapsed sections of uterus.
Treatment usually requires heavy sedation or general anesthesia followed by manual reinsertion of the uterus into the pelvic cavity followed by suture closure of the vulva to prevent recurrence.
Broad-spectrum antimicrobial therapy is essential because of the inevitable contamination of the uterus once externalized.
Endotoxic shock and hemorrhage are not uncommon in dogs with a chronically prolapsed uterus that has been untreated for more than 24 hours.
An ovariohysterectomy is recommended in many cases where there is extensive damage to the uterus or extreme difficulty in internalized the everted uterine horn.
