Vaginal Hyperplasia and Prolapse in Cats
A mass protruding from a cat's vaginal area is referred to as vaginal hyperplasia and prolapse. The condition is similar in nature to fluid-filled tissue (edema). If serious, it can prevent normal urination. Vaginal hyperplasia affects cats all ages, although it is found more commonly in younger animals. The outcome is positive for most cats, but the chance of the condition recurring is high.
Vaginal hyperplasia and prolapse can affect both dogs and cats. If you would like to learn more about how this disease affects dogs please visit this page in the PetMD pet health library.
Symptoms and Types
There are several signs that may be noticed with this medical disorder, including the licking of the vaginal area, unwillingness to copulate, and painful urination (dysuria).
Type 1 hyperplasia occurs when there is a slight protrusion of the mass, even though it does not exit the vulva itself. Type 2 hyperplasia, on the other hand, is when the vaginal tissue actually protrudes through the vulvar opening. Type 3 hyperplasia refers to the donut-shaped mass which can be seen externally.
Upon physical examination, a round mass may be noticed protruding the cat's vulvar area. A vaginal examination will be performed to determine the severity and type of the condition. The cat's tissue may feel dry to the touch.
Treatment is typically done on an outpatient basis. If there is a protruding mass, it is important to keep the area clean and watch for problems urinating, as they are common. The recurrence rate of vaginal hyperplasia following treatment is high (66-100%).
Living and Management
If your cat is unable to urinate, this is a sign of a serious medical condition and should be treated immediately, as there may be complications with the cat's urethra.
There are currently no prevention methods for this medical condition.
