The Electrourogram, II. Experimental Study

Abstract

Electro- nephrograms, tracings from the kidney, were obtained in rabbits. The kidney produces electrical potentials which can be registered. The renal curves can be differentiated from the electrocardiogram as well as from the pneumogram. The renal potentials are different from the ureteral potentials. The curves change according to whether the kidney is sandwiched between electrodes or needles are used. Each anatomical part of the kidney writes partial electrical potentials of its own. Changes in the curves occur through diuresis and when antidiuretic measures are applied. If the potentials of both kidneys are registered simultaneously, one kidney is always more active than the other and its tracing shows higher amplitudes.
