In older gravid sows in the last stage of gestation or after pariturition lateroflexion of the urinary bladder into the space between the vagina and the pelvic wall occasionally occurs. The reposition of the displaced urinary bladder by exerting external pressure either on the vulva or the perineum is usually unsuccessful. Only after the bladder has been emptied by a catheter spontaneous reposition does occur. In two cases displacement of the urinary bladder occurred immediately after normal pariturition. In both cases relapses were observed after the removal of the implanted balloon catheter. Both sows had the urinary balloon catheter reinserted and it was left in place until the weaning of the piglets. There were no complications during the whole lactation period. Both sows reared their piglets and could then be slaughtered.
在妊娠后期或分娩后的老龄妊娠母猪中，偶尔会发生膀胱向阴道与骨盆壁之间的间隙侧屈。通过对外阴或会阴施加外部压力来复位移位的膀胱通常是不成功的。只有在通过导尿管排空膀胱后，才会发生自发复位。有两例膀胱移位在正常分娩后立即发生。在移除植入的球囊导管后，两例均观察到复发。两头母猪均重新插入了尿囊导管，并一直留置到仔猪断奶。在整个哺乳期均无并发症。两头母猪均养育了仔猪，随后可以屠宰。
