An isolated kidney obtained from a donor dog was perfused at constant pressure with blood from the femoral artery of a recipient dog. The left atrial pressure of the recipient dog was increased by approximately 20 cm H20 by inflating a balloon in the left atrium. Left atrial distension caused an increase in urine flow and sodium excretion from the isolated perfused kidney and on a few occasions from the dog's own kidneys. The results support the view that a blood borne agent is responsible for the diuretic response to left atrial distension.
