Attention to the processes involved in renal counterbalance will tend to stimulate a search by both surgeon and clinician for better tests of renal function than are now available, and mutual benefit will result. A closer correlation by both groups of practitioners of the so-called surgical and medical lesions of the kidney is desirable. The surgical specialist cannot safely separate his field from the conservative eye of the internist, and in many nephritides joint study also is desirable. Renal function constitutes a work bench already equally familiar and important, and a more thorough conception of renal counterbalance in its relation to medical and surgical diseases of the kidney will tend to destroy the artificiality of their separation as well as to increase the value of functional studies themselves.
In 1922, an experimental consideration of renal counterbalance was presented before the American Association of Genito-Urinary Surgeons, but the published record in
