Excerpt: ... terization in the sense that the similar secretion of normal kidneys can no longer be doubted. This conclusion, however, has a wide-reaching practical significance, because by reason of this fact we are now more than ever in a position to calculate from the secretion of each kidney collected simultaneously, and during only a relatively short time, what proportion the work of each kidney bears to the total amount. We will now still further describe the single methods by which in conjunction with the catheterization of the ureters the amount of work of each kidney may be estimated. (ft) The Elimination Of Nitrogen By Each Kidney. The quantitative determination of the urea, that is, of the N-total in the excretion of each kidney, is the most obvious and accordingly the first method employed in connection with catheterization of the ureters in securing information as to the work of each kidney. As early as 1897, such investigations were published by Guyon and Albarran. The results at any rate were generally obtained by conducting outside the body, by means of a ureter catheter, and for a period of from several to twenty-four hours, the urine of the kidney supposed to be diseased. The bladder urine during this time served as a measure of the work of the other kidney. Our method, as is easily evident, is to be preferred, since, without too great annoyance to the patient, it allows us to just as accurately learn the conditions of the N elimination of both kidneys. We will later come back to a consideration of the results obtained in this way, and their diagnostic application when we report the single histories of the patients, and now we wish only to speak in general of the value of the method. The elimination of the waste products of proteid metabolism is certainly a ...
