"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]
Chronic kidney disease results in worse all-cause mortality (the overall death rate) which increases as kidney function decreases. [90] The leading cause of death in chronic kidney disease is cardiovascular disease, regardless of whether there is progression to stage 5. [90] [91] [92]
Among the accidental causes of renal failure is the crush syndrome, when large amounts of toxins are suddenly released in the blood circulation after a long compressed limb is suddenly relieved from the pressure obstructing the blood flow through its tissues, causing ischemia. The resulting overload can lead to the clogging and the destruction ...
Blood pressure readings do vary but experts recommend that blood pressure should not range above 140/80. Secondly, high blood pressure is a silent disease and thus it is vital for all diabetics to regularly check their blood pressure or have it checked at a doctor's office on a regular basis.
Pregnancy: unclear cause. Cancers: tumours in the kidney can operate in the same way as kidney disease. More commonly, however, tumors cause inessential hypertension by ectopic secretion of hormones involved in normal physiological control of blood pressure. Drugs: Heavy alcohol use; NSAIDs [65] MAOIs, SNRIs, [66] and TCA antidepressants [65]
Kidney ischemia [1] is a disease with a high morbidity and mortality rate. [2] Blood vessels shrink and undergo apoptosis which results in poor blood flow in the kidneys. More complications happen when failure of the kidney functions result in toxicity in various parts of the body which may cause septic shock, hypovolemia, and a need for surgery. [3]
Renal azotemia (acute kidney failure) typically leads to uremia. It is an intrinsic disease of the kidney, generally the result of kidney parenchymal damage. Causes include kidney failure, glomerulonephritis, acute tubular necrosis, or other kidney disease. [3] The BUN:Cr in renal azotemia is less than 15.
Because necrosis is often not present, the term acute tubular injury (ATI) is preferred by pathologists over the older name acute tubular necrosis (ATN). [1] ATN presents with acute kidney injury (AKI) and is one of the most common causes of AKI. [2] Common causes of ATN include low blood pressure and use of nephrotoxic drugs. [2]
