Vaginal hyperplasia and prolapse refers to a mass which protrudes from the vaginal area. The condition is similar in nature to fluid-filled tissue (edema). If serious, it can prevent normal urination. Vaginal hyperplasia affects dogs of all ages, although it is found more commonly in younger animals. A protrusion from the vaginal opening may be due to vaginal hyperplasia or vaginal prolapse. Vaginal hyperplasia maybe caused by high hormone levels causing thickening of the vaginal mucosa until it protrudes from the labia of the vagina; vaginal prolapse occurs when a portion of the vagina protrudes out of the labia which maybe caused by.
Vaginal hyperplasia interferes with copulation and reluctance to breed may be the only symptom. Occasionally, the prolapse continues throughout pregnancy or recurs at the delivery of puppies 1. Some affected dogs will exhibit straining or painful urination but it is rare that the dog will be void of any symptoms. How common is vaginal hyperplasia? In vaginal hyperplasia, a proliferation of the vaginal mucosa, usually originating from the floor of the vagina anterior to the urethral orifice, occurs during proestrus and estrus as a result of estrogenic stimulation. Occasionally, the prolapse continues throughout pregnancy or recurs at parturition.
Vaginal Hyperplasia and Prolapse Symptoms and Treatments in Dogs - Vaginal hyperplasia is an exaggerated swelling of the vaginal lining that occurs during proestrus and estrus in response to the influence of estrogen. When the swollen vaginal mucosa can no longer be contained within the vagina, it bulges through the vaginal lips. In vaginal prolapse, the swollen, protruding vaginal tissue resembles what’s often described as a “donut-shaped” mass. While the primary cause of vaginal prolapse is estrogen stimulation, other causes include vaginal hyperplasia (a proliferation of the vaginal mucosa) and genetic predisposition.
Vaginal Prolapse/Hyperplasia. What is Vaginal Prolapse/Hyperplasia and How Does it Arise? Vaginal prolapse/hyperplasia occurs uncommonly, usually during proestrous and oestrous, as a result of fluidy enlargement of vaginal tissue. 360 o protrusion of the tissue lining the vagina may occur in vaginal prolapse. In case of vaginal hyperplasia, the problem originates from a stalk of vaginal floor.
