Vessel lesion in chronic unilateral pyelonephritis and their relation to hypertension
Abstract
Histologic examination of blood vessels in scrarred and nonscarred areas of the affected kidneys from 20 pts with chronic unilateral pyelonephritis was carried out. In addition the correlation of PRA with the FENa+, MBP, and patient's age was examined, in an effort to identity the relationship between BP level, scar process and Renin-Angiotensin system. Vascular changes were greater in scarred than in the nonscarred areas, particularly in hypertensive patients. Severe vascular changes in scars were seen only in cases with hypertension. PRA was negatively correlated with MBP and with patients age (r= -0.7, p<0.05). Multiple linear regression analysis, with the severity of vascular lesion as dependent variable and the pts, age, sex, MBP, Clcr, and PRA as independent variables, reveals that age is, the main factor which determine the severity of vascular changes (p=0.05) although the contribution of MBP must not be ignored (p=0.2). Linear with two predictor variable analysis reveals pts a ...
