anal prolapse

see rectal prolapse.

cloacal prolapse

caused in companion birds by parasitic enteritis.

eye 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.

uterine prolapse

vaginal prolapse

Kinking of the urethra may cause obstruction and eventual rupture of the bladder. Called also estral eversion, vaginal hyperplasia.
