AMERICAN VETERINARY COLLEGE— Hospital Dep’t. 
INVERSION OF THE BLADDER. 
By W. G. Coates, M.D., D.V.S., Assistant Veterinary Surgeon. 
The following case came under my observation, and is of 
interest because of its rareness. 
I have sought veterinary literature relative to inversion of 
the bladder, and find it a very rare affection, occasionally tak¬ 
ing place previous to parturition or after delivery, but have 
failed to discover any article on the subject where it has not 
been a complication in the parturient state. 
On August 14, 1889, a black mare, nine years of age, me¬ 
dium height, in good bodily condition and used for hacking 
purposes, was admitted to the Hospital Department of the 
American Veterinary College with the following history: 
had been in possession of present owner three years, always in 
apparent good health and never noticed anything abnormal 
except an occasional desire to micturate large quantities of 
urine of a pale color. Early in the morning of the day in 
question, the owner on entering the stable, noticed the mare 
elevating and switching her tail and making attempts to uri¬ 
nate. Not paying particular attention to this, gave her a feed 
of oats and returned again at noon to find her acting uneasily, 
as if with colicky pains. On the floor behind her was a little 
urine streaked with blood, which alarmed him considerably, 
and he sent for a veterinarian in the vicinity, who came immedi¬ 
ately and discovered a reddish looking mass protruding from 
the vulva, which he thought was a prolapsus of the uterus. 
After making several unsuccessful attempts to reduce the tu¬ 
mor, and knowing it a serious and troublesome case, advised 
the owner to send the animal to the hospital, where the facili¬ 
ties were much better for treating a case in her condition 
than in the owner’s stable.
