The surgeons, who once thought a floating kidney could be permanently fixed in its place by stitching, have now concluded that this is very doubtful, and the treatment of this displacement is never very satisfactory by any method. Still, some success has followed long rest in the supine position, which encourages the kidney to return to its normal place, until careful full feeding has renewed or increased the fatty cushions which hold it up. It is best during the first weeks of treatment not to allow the patient to sit or stand, or if she should be unable to avoid the occasional need for these positions, an abdominal binder must be applied by the nurse and drawn tightly before she moves. The masseuse is directed to avoid any movements which might further displace the organ, and may cautiously push it upward and hold it there with one hand while with the other the manipulation of the abdomen is performed. However long it may require, the patient should not get up until examinations, supine, lateral, prone, and erect, combine to assure us that the kidney is replaced. Repeated investigation of this point will be required,--for the kidney will sometimes be in place for a little while and next day or even a few hours later have slipped down again. Before any exertion is permitted, even ordinary walking, an accurate close-fitting abdominal belt with a kidney-pad should be applied. Those kept in stock are seldom properly adjusted, and usually have the pad in the wrong place. If rightly made, they can be worn with comfort and tight enough to be useful. If not rightly made, they are useless instruments of torture.
