Uterine prolapse is a serious reproductive emergency in female rabbits where the uterus turns inside out and protrudes through the vaginal opening to the outside of the body. This condition occurs most commonly immediately following or within hours after kindling, when the uterus is enlarged, the cervix is dilated, and the tissues are stretched and traumatized from the birthing process. Uterine prolapse represents a true medical emergency requiring immediate veterinary intervention, as the exposed uterine tissue is at risk for trauma, contamination, necrosis, and life-threatening hemorrhage. Without prompt treatment, uterine prolapse can be fatal within hours due to shock, blood loss, or tissue death.
The mechanics of uterine prolapse involve the uterus essentially inverting and being pushed out through the vaginal canal. This can occur when strong uterine contractions continue after the kits have been delivered, when the doe strains excessively during or after delivery, or when tissues weakened by multiple pregnancies fail to maintain normal organ position. The prolapsed tissue appears as a red, fleshy mass protruding from the vaginal area, which may be alarming for owners who have never witnessed this condition. In some cases, only a portion of the uterus prolapses, while in severe cases, the entire organ may be everted. The exposed tissue rapidly becomes swollen, traumatized, and potentially infected if not protected and treated quickly.
The impact of uterine prolapse on the affected rabbit is severe and multisystemic. The condition causes significant pain, which rabbits express through teeth grinding, reluctance to move, and refusal to eat. Exposed uterine tissue bleeds readily and loses fluid, contributing to hypovolemia and shock. The doe may ignore her newborn kits due to her own distress, putting them at risk if they are not kept warm and eventually fed. Straining associated with prolapse can worsen the condition and may cause additional tissue damage or prolapse of other structures. Secondary gastrointestinal stasis is likely to develop due to pain and stress, adding another potentially fatal complication to an already critical situation.
Treatment for uterine prolapse is surgical and urgent. The exposed tissue must be cleaned, protected, and either replaced into the body cavity or removed through ovariohysterectomy. The decision between replacement and removal depends on the condition of the prolapsed tissue, the breeding value of the doe, and the risk of recurrence. In most pet rabbit situations, ovariohysterectomy is the recommended treatment, as it eliminates the risk of recurrence and addresses the underlying reproductive tract that predisposed to the prolapse. With immediate, appropriate treatment by a rabbit-savvy veterinarian experienced in emergency surgery, the prognosis can be good, but outcomes deteriorate rapidly with any delay in seeking care.
