[4] "Hypertensive" refers to high blood pressure and "nephropathy" means damage to the kidney; hence this condition is where chronic high blood pressure causes damages to kidney tissue; this includes the small blood vessels, glomeruli, kidney tubules and interstitial tissues. The tissue hardens and thickens which is known as nephrosclerosis. [2]
A diagram explaining factors affecting arterial pressure. Pathophysiology is a study which explains the function of the body as it relates to diseases and conditions. The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure.
Renal artery stenosis (RAS) is the narrowing of one or both of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia.This narrowing of the renal artery can impede blood flow to the target kidney, resulting in renovascular hypertension – a secondary type of high blood pressure.
Treatment is directed at the underlying cause. Other efforts include managing high blood pressure, high blood cholesterol, and infection risk. A low-salt diet and limiting fluids are often recommended. [1] About 5 per 100,000 people are affected per year. [3] [4] The usual underlying cause varies between children and adults. [4]

Renovascular hypertension is caused by diminished blood flow to one or both kidneys. As a result, the kidneys release hormones that cause the body to retain sodium and water, leading to elevated blood pressure. There are many causes of decreased blood flow to the kidneys. These include: [5] Atherosclerotic renal artery stenosis; Fibromuscular ...
