| Abstract: | The bladder of a 750-kg Clydesdale mare had everted through the urethra into the vagina immediately after parturition. The bladder was reinverted into the peritoneal cavity by an attending veterinarian, but 4 days later, the bladder was everted again in the vagina. The mare was able to void urine through both ureters, which could be seen in the mucosal surface of the bladder. The everted bladder had become edematous and could not be reinverted through the urethra. A considerable portion of the fundus was necrotic. The mare was administered xylazine epidurally to induce perineal analgesia, and the necrotic portion of the bladder was resected and healthy bladder tissue was opposed with a double layer of simple continuous sutures. The urethral sphincter was longitudinally incised through the vaginal mucosa to allow reinversion of the bladder through the urethra. A purse-string suture inserted in the urethral opening decreased the urethral diameter and prevented recurrence of the condition. An inflated Foley catheter was maintained in the bladder for 5 days. The mare recovered normal urination after the catheter was removed. |
