PostSubject: Vaginal hyperplasia   Sun Jan 13, 2008 9:02 pm

Vaginal hyperplasia is an exaggerated response by the vaginal tissue to estrogen during certain phases of the estrus (heat) cycle. The vaginal tissue becomes swollen and may protrude through the vulva, or external female genital organ, as a tongue-shaped mass.

Vaginal hyperplasia is most common in young intact female dogs and is thought to be caused by estrogen stimulation. There is a genetic predisposition to developing vaginal hyperplasia.

The breeds most commonly affected include the Labrador retriever, Chesapeake Bay retriever, boxer, English bulldog, mastiff, German shepherd, St. Bernard, Airedale, springer spaniel, walker hound and Weimaraner.

What to Watch For


A protrusion of a round tissue mass from the vulva

Licking of the vulvar area

Painful urination

Failure to allow breeding

Diagnosis


Baseline tests, including complete blood count (CBC), biochemical profile, and urinalysis, are usually within normal limits.

Careful inspection and examination of the vulvar area generally reveals a fairly classic appearance of overgrown tissue.

A biopsy may be recommended in an old bitch in order to rule out the possibility of cancer.

Treatment

Management of vaginal hyperplasia can be difficult. If the patient can urinate, treatment is generally not an emergency and outpatient care is recommended. If there is a blockage due to the mass, immediate hospitalization and intervention is necessary.

Given enough time, most all cases of vaginal hyperplasia are reversible, as certain periods of the estrus cycle allow for it to resolve. Treatment includes:


Daily cleansing of the affected area with saline washes


Lubrication with appropriate jellies


Preventing trauma


Padding the environment to avoid direct exposure to concrete or abrasive surfaces


Elizabethan collar to eliminate the possibility of excessive licking and chewing


Diapers to minimize exposure of the tissue to the environment and the patient herself


A urinary catheter


Severely affected patients require surgical removal of the hyperplastic tissue, especially in cases of severely damaged or irreparable tissue or urinary blockages.

Vaginal hyperplasia (currently called vaginal edema...Root likes to call it vaginal prolapse!) usually occurs in younger, large breed dogs at estrus. It results from excess reaction to normal estrogen concentrations. It is actually edema of the tissue.
You see a large red mass protruding from vulva. If the condition is chronic, the mass may be dried out. To make a definitive diagnosis examination of the mass will reveal a broad base, floor involved with the urethral orifice under the mass.
Spontaneous regression will usually occur with conservative therapy. Ovariohysterectomy will prevent the occurrence in the future.
Amputation is sometimes needed, and the condition will recur to some extent.
You will probably have to perform artificial insemination if the bitch is to be bred.
If it is not a breeding bitch you can administer OvaBan at a dose of 2.2 mg/kg for 7 days. Be sure to keep the mass moist while doing conservative therapy.

Vaginal Prolapse

Vaginal prolapse, unlike vaginal hyperplasia, rarely occurs at estrus, but is most commonly seen post partum.
The entire circumference of vagina involved and the hole you see is in the middle. The mass is usually partially reducible.
The best treatment is amputation.
