Prolapse of the Bladder 823 



The symptoms consist of the presence of the prolapsed organ 

 in the vagina or vulva, with its fundus turned backward toward 

 the vulvar opening, or protruding through it, according to the 

 degree of distension. The organ is right side out, and shows the 

 peritoneum upon its surface. A careful examination of the floor 

 of the vagina will reveal the presence of a rupture, through which 

 the organ protrudes. In the mare or cow, a further test of the 

 character of the injury may be made by inserting a finger into 

 the urethra and passing it along that canal until it turns upward, 

 to reappear again in the vagina inside the prolap.sed organ. 



The indications in such cases are to return the bladder to its 

 proper position, under aseptic precautions, and suture the wound 

 in the floor of the vagina, bringing the peritoneal surfaces of the 

 vagina in contact. If the bladder should be so greatly distended 

 that* it is exceedingly difficult or impossible to return it through 

 the rupture, the urine may be drawn off by pa.ssing a small trocar 

 or hypodermic needle into the distended organ and allowing the 

 urine to escape.

 Uterus. Uterine Prolapse. 



Eversion or prolapse of the uterus is a common and formidable 

 obstetric accident, especially liable to occur in cows, chiefly in 

 those which are largely confined in stables for dairying purposes. 

 It is possible in any domestic animal, though not common in the 

 smaller species. 



The accident consists at first of an invagination of the anterior 

 extremity of a cornu into the succeeding portion, essentially in 

 the same manner as intussusception of an intestine. Should the 

 invagination continue, the invaginated portion finally appears at 

 the vulva, and, passing beyond, constitutes a prolapse or evagina- 

 tion. When the eversion becomes complete, there is necessarily 

 involved with it a prolap.se of the vagina as well. In the incom- 

 plete forms, and in the beginning of the displacement, there 

 exists merely an intu.ssusception or invagination of one of the 

 horns to a limited degree, and it is only by the extension of this 

 that the accident becomes complete. In uniparious animals, 

 only the gravid cornu becomes everted, but the non-gravid cornu 

 is prolapsed along with the everted gravid one, hidden from 

 view and recognizable only as a diverticulum extending inwards.
