"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]
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 ...
Obstruction of the renal arteries supplying the kidney that result in elevated blood pressure is known as renovascular hypertension.It is thought that decreased perfusion of renal tissue due to stenosis of a main or branch renal artery activates the renin–angiotensin system.
It is presumably a manifestation of hypertensive kidney disease. Benign nephrosclerosis refers to the renal changes most commonly occurring in association with long-standing hypertension. It is termed benign because it rarely progresses to clinically significant chronic kidney disease or kidney failure. [1]
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.
Risk factors for kidney disease include diabetes, high blood pressure, family history, older age, ethnic group and smoking. For most patients, a GFR over 60 (mL/min)/(1.73 m 2) is adequate. But significant decline of the GFR from a previous test result can be an early indicator of kidney disease requiring medical intervention.
Volume of blood plasma delivered to the kidney per unit time. PAH clearance is a renal analysis method used to provide an estimate. Approximately 625 ml/min. renal blood flow = (HCT is hematocrit) Volume of blood delivered to the kidney per unit time. In humans, the kidneys together receive roughly 20% of cardiac output, amounting to 1 L/min in ...
Glomerulonephrosis is a non-inflammatory disease of the kidney presenting primarily in the glomerulus (a glomerulopathy) as nephrotic syndrome. The nephron is the functional unit of the kidney and it contains the glomerulus, which acts as a filter for blood to retain proteins and blood lipids. Damage to these filtration units results in ...
