Background and history

This is an uncommon condition but rather confusing when it appears, the bladder turns inside out and protrudes from the lips of the vulva. It arises when there is a large urethral opening at the floor of the vagina and complete loss of muscle tone in the sphincter.

Clinical signs

This is an uncommon condition and usually only occurs in the sow. The bladder turns inside out and protrudes from the lips of the vulva.

It can be confused with an early prolapse of the uterus but examination will show that is like a small balloon.

It is usually seen after mating. Such animals should be culled immediately if it can not be replaced.

Diagnosis

Veterinary advice is suggested if in doubt. It can be confused with vaginal prolapse and vaginal polyps.

Causes

• It arises when there is a large urethral opening at the floor of the vagina and complete loss of muscle tone in the sphincter.
• Possibly cystitis.
• The presence of calculi and continual straining.
• Unknown factors.

Treatment

• The everted bladder can usually be returned to its former position using obstetrical fluid. The tissues are gently pushed back into the vagina and the bladder returned. This may be a task for your veterinarian.
• Give antibiotic cover by injections for 3 days.
