    Prolapse, or Eversion of the Bladder which is largely dependent upon the duration of the eversion It the eversion is recent, or if the bladder has not protruded be¬ yond the vulva to any great extent, or has not been seriouslv abraded or injured, it presents a fresh mucous surface. Upon eitlRr side, near the neck of the tumor, may be observed the two uretral openings, from which urine escapes drop by drop, or sometimes in small jets during an expulsive effort. If not much swollen, the bladder may remain almost or completely hidden especially when the animal is standing, to become exposed when she is lying down or straining. I'.\ ersion of the bladder is to be differentiated chiefly from Item,a of the bladder, through a rent in the vaginal floor, and rom hematoma or tumors in the vagina or vulva. In rupture of the vaginal floor with hernia of the bladder, the peritoneal surface of the bladder remains external, and the ureters, still emptying inside the organ, may cause it to become distended with urine. The rupture in the vaginal floor is recognizable. The urethra is present in its normal position on the vulvar floor. Through it the finger or a catheter may be passed into the herniated organ. The niucons surface of the everted bladder is external, and the ureters open upon the external surface. The viscus does not become dilated with urine. The meatus urina- rius is absent. In the handling of eversion of the bladder, the organ should rst be thoroughly cleansed by washing with a non-irritant fluid, such as a physiologic saline solution. The organ should be examined and proper attention given to any injuries. If any perforations of the walls exist, these should be carefully closed by means of sutures, so applied that the peritoneal surfaces of the lips of the wounds are brought into contact. If a portion of the wall of the organ has been severelv lacerated or contused or has become so badly infected or otherwise damaged that its recovery cannot well be expected, the damaged portion should je removed and the edges of the wound brought together, thus amputating as much of the organ as may be necessary. In such an operation it is essential to preserve the outlet of each ureter. Alter due preparation, the organ is to be returned into its normal position, through the urethral opening. Usually the operation is not difficult, especially if the organ has not been long
