The Pathophysiology of Acute Renal Failure Essay - 1449.

Abnormal functions that can cause acute renal failure are that the body cannot regulate acid-base balance of bodily fluids, regulation of one’s blood pressure which affects waste products not being filtered from the body, and irregularities of red blood cell production.

Acute renal failure, also known as acute kidney injury is described to be a rapid loss of kidney function, or a rapid decline in renal filtration function. The first signs of acute renal failure can be found by a rise in serum creatinine concentration or azotemia, which is a rise in blood urea nitrogen (BUN) concentration.

Intrarenal is caused by inflammation, drugs such as antibiotics and infections, for example, glomerulonephritis, which is caused by the strep bacteria. 3. Postrenal is the least common form of ARF. This occurs when there is a sudden obstruction of urine flow that can result from a kidney stone, enlarged prostate, injury or a bladder tumor.Include pre-renal, intrarenal and postrenal causes. Acute renal failure is a sudden decrease of kidney function often characterized by the loss of homeostatic equilibrium of the internal medium causing waste accumulation in the blood.Out of the 3 causes of acute renal failure pre renal is the most common. It may result in hypoperfusion and ischemia. Pre renal is caused by a sudden drop in blood pressure or renal interruption of blood flow from the kidneys from sudden severe injury or illness.


Acute renal failure characterized by three common findings: reduced creatinine clearance, excessive accumulation of nitrogen compounds in the blood known as Azotemia, and hyperkalemia .reference Creatinine is a waste product of muscle metabolism and filtered freely by glomeruli without reabsorption causing levels to increase when glomerular filtration is reduced.This is likely due to the lack of clearance of BNP from the body due to his renal failure. His BNP may also be elevated due to his congestive heart failure, due to the increase workload on the left ventricle.

There are two types of renal malfunctions: acute and chronic ones. Acute kidney failure may be caused by poisoning or trauma and is generally treatable. Chronic malfunction is much more serious, as it is developing over months and years, being in a passive form, when it is hard to identify the problem.

Acute renal failure is characterized by the following phases Prerenal, Intrarenal, and Postrenal. In the prerenal phase this is the most common that results in hypoperfusion and ischemia resulting in acute renal failure.Prerenal causes may include decreased cardiac output,hypovolemia,peripheral vasodilation, renal vascular obstruction.

Normocytic normochromic aneamia is usually seen in acute renal failure. Anaemia rises because of the lack of erythropoiesis and production ureamia, which reduces the life span of red cells in circulation. Acute renal failure can be linked with MAHA (Microangiopathic haemolytic anaemia) and HUS (haemolytic uremic syndrome).

Kidney disease is a slow process in which the kidneys can shut down and waste can be released into the blood flow for several different reasons. Some of these reasons include diabetes, Anemia, and Amyloidosis. Out of all the cases of diabetes in the United States one hundred thousand of these have Kidney failure due to diabetes.

Most acute intrinsic AKI is caused by ischemia or nephrotoxins and is classically associated with ATN. AKI may occur in someone either with previously normal renal function or as an acute and unanticipated deterioration in function in the setting of previously established chronic kidney disease.

Chronic renal failure is a worldwide public health problem. Millions of Americans are affected by this disease each year. It is a common condition in which there is progressive loss of kidney functioning. The loss of function usually takes months or years to occur, sometime not appearing until kidney function is less than one-tenth of normal.
