Abstract
Renal diseases are a very frequent cause of secondary hypertension. Renal parenchymatous hypertension outweighs renovascular hypertension.
In bilateral renal impairment the hypertension often accompanies primary and secondary glomerulonephritis and also autosomal dominant polycystic kidney disease. Hypertension also occurs in congenital and acquired unilateral renal impairment.
The prevalence and severity of renal parenchymatous hypertension depends on the age, body weight, type and duration of renal disease and the range of filtration function disorder. Enhanced sodium and water retention along with imbalances in the operation of numerous vasoactive mediators plays the greatest role in the multifactorial pathogenesis of renal hypertension
