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.
一匹750千克重的克莱兹代尔母马在分娩后膀胱立即经尿道翻入阴道。一名随行兽医将膀胱复位至腹腔，但4天后，膀胱再次翻入阴道。母马能够通过两侧输尿管排尿，这在膀胱黏膜表面可见。外翻的膀胱已出现水肿，无法经尿道复位。膀胱底部相当大一部分已坏死。对母马进行硬膜外注射赛拉嗪以诱导会阴部镇痛，切除坏死的膀胱部分，并用双层单纯连续缝合法对健康的膀胱组织进行对合。通过阴道黏膜纵向切开尿道括约肌，以使膀胱经尿道复位。在尿道开口处插入荷包缝合线以减小尿道直径并防止病情复发。在膀胱内留置一根充气的弗利导尿管5天。导尿管拔除后，母马恢复了正常排尿。
