FUNCTION OF THE SEPARATE KIDNEYS IN HYPERTENSIVE SUBJECTS

Abstract

The presence of a unilateral pyelographic abnormality in a hypertensive subject has been accepted as having etiologic significance, the assumption being that an abnormal pyelogram is indicative of a pathologic change resulting in obstruction to the renal blood flow and that the resulting ischemic renal tissue is responsible for elevated blood pressure. This report is concerned with the correlation of pyelography and renal function in the separate kidneys of 21 hypertensive subjects. In addition, the effect on renal function of operative procedures designed to increase the renal blood flow will be reported for a small group of hypertensive subjects. SELECTION OF SUBJECTS Twenty-one subjects with well established essential hypertension were chosen at random from the hypertension and nephritis clinic of the New York University Medical Clinic and from the wards of the Third (New York University) Medical Division of Bellevue Hospital, without regard to the presence or absence of signs
