anal prolapse

see rectal prolapse.

cloacal prolapse

caused in companion birds by parasitic enteritis.

eye prolapse

the eyeball is displaced from the orbit and is lying on the lower eyelid.

fat prolapse

see perivaginal fat prolapse.

oviduct prolapse

a minor prolapse of oviductal mucosa may stimulate cannibalism in others and the entire oviduct be removed via the cloaca.

parturient bladder prolapse

see parturient urinary bladder prolapse.

preputial prolapse

see preputial eversion.

rectal prolapse, prolapse of rectum

protrusion through the anus of the mucosa only or the complete wall of the rectum. Uncommon in most species but commonplace in the pig because of anatomical weakness in the area, especially in some breeds. The feeding of estrogens exacerbates the tendency.

prolapse retainer

1. a frame made of strong wire or thin metal rod and shaped like a lattice with obvious apertures for defecation and urination; strapped to the rear end of the cow so that the perineum will not bulge when the animal strains.

2. a bottle-shaped appliance sewn in to the vagina to prevent prolapse of the vagina.

third eyelid gland prolapse

see cherry eye.

uterine prolapse

displacement of the uterus so that the cervix is within the vaginal orifice (first-degree prolapse), the cervix is outside the orifice (second-degree prolapse), or the entire uterus is outside the orifice (third-degree prolapse). May be related causally to hypocalcemia in cattle.

vaginal prolapse

edematous enlargement of vaginal tissue during estrus. Usually the prolapse contains only the mucosa of the ventral floor, but it may also contain the urinary bladder or the cervix. Kinking of the urethra may cause obstruction and eventual rupture of the bladder. Called also estral eversion, vaginal hyperplasia.
