Renal tuberculosis and hypertension: value of the renal vein renin ratio.
We applied the central renal vein renin ratios in a group of patients with unilateral renal tuberculosis and hypertension to see whether the diseased kidney was involved in the pathogenesis of the elevated blood pressure. Of 20 patients 11 were nephrectomized, 7 had positive renal vein renin ratios and normal peripheral plasma renin activity; only 2 kept their blood pressure in control without medication. From 5 without a positive index, only 1 kept his blood pressure in control without medicine 1 year after surgery. The renal vein renin ratio has to be interpreted in light of other parameters, such as blood pressure, peripheral renin--if high the more the chance of being significant--and global renal function. The renal vein renin ratio alone per se gives poor information on the pressor role of a unilateral tuberculous kidney.
