Pre-renal cause is the failure of the urinary mechanism to work due to perfusion of the kidney caused by the depression of the glomerular filtration rate of the kidney which is the volume that is filtered in the renal system and azotemia, an elevation of the nitrogen containing urea. The pre-renal causes is attributable to the low volume depletion, low cardiac output, low blood pressure and decreased arteriolar tone which is more prevalent to people that has renal artery stenosis.
Intrarenal causes are the damage of the kidney parenchyma that also consists of nephrons which is the functional unit of the kidney. The intrarenal causes are as a result of tubular injury due to ischemia, arterial venous obstruction or hemorrhage, glomerulonephritis, infiltrative disease like leukemia and tubulointerstitial nephritis in which the spaces in the kidney is inflamed.
Postrenal cause is caused by urinary tract obstruction including the renal pelvis, urinary bladder, urethra and the ureters which then results in the dilation of the renal pelvis, progression of this can lead to decrease in the renal function which increases intratubular pressure and decreases the capillary filtration pressure. This kind of condition is correlated to people who have benign prostate hypertrophy, hyperuricemia, gout, thrombosis and nephrolithiasis.

6. What are the short term and long term nursing goals for a client with acute renal failure?
The short and long term goals for patient who has acute renal failure is to have a normal range of fluid and electrolytes, not having any complications due to inadequate interventions that will be made. Nurse needs to balance the activities and rest due to some reasons like increased rate of metabolism can also increase the production of waste products.

- Explain the pathophysiology of acute renal failure. Include prerenal intrarenal and postrenal causes. According to the Mayo Clinic Staff (2012), acute kidney renal failure occurs abruptly when your kidneys lose their filtering abilities and cannot filter waste products from your blood. This is also known as acute renal failure or acute kidney injury. When this happens, high levels of waste may become accumulated in your blood and will alter your bloods chemical make up causing them to get out of balance.... [tags: Acute Renal Failure]

- The pathophysiology of acute renal failure is divided in 3 different causes. 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. Intrarenal is caused by direct damage to the kidneys either by inflammation, toxins, drugs, infection or reduced blood supply. Postrenal is a sudden obstruction of urine flow due to an enlarged prostate, kidney stones or bladder tumor or injury.... [tags: Pathophysiology of Acute Renal Failure]

- Acute renal failure (ARF), also referred to as acute kidney injury (AKI), is the abrupt loss of renal function; the kidneys inability to perform its functions of filtering wastes from the blood, regulating blood pressure, and maintaining electrolyte balance in the body. This sudden loss of functioning occurs within less. Most patients who experience ARF are already hospitalized or may be in ICU for other medical conditions, although some patients have no signs or symptoms but a diagnosis is made from lab results performed for other medical reasons....

- Explain the pathophysiology of acute renal failure. 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. Aside from accumulation of waste products like nitrogen and urea, it is also characterized by a sudden decrease of glomerular filtration rate (GFR) which disables the kidney from filtering waste products that is harmful to the body....

- Explain the pathophysiology of acute renal failure. Include prerenal, intrarenal and postrenal causes. The pathophysiology of acute renal failure takes place when the kidney no longer works properly. Prerenal causes of acute kidney failure are a lack of prefusion to the kidney. The primary cause of prerenal is ischemia, or inadequate blood flow to the kidney. This lack of perfusion leads to renal failure. Some causes of prerenal acute renal failure can include blood lose or dehydration. Intrarenal causes are damage to the kidney.... [tags: Disease ]

Acute renal failure is when the kidneys have suddenly stopped working this disease disables the body’s mechanism of excreting waste products and maintaining fluid electrolyte balance. According to WebMD, the causes are characterized as a sudden decrease of blood flow to the kidneys, damage from some medications, poisons, or infections, a sudden blockage that stops urine from flowing out of the kidney....

- Acute Renal Failure According to medline plus, “Acute kidney failure is the rapid loss your kidneys' ability to remove waste and help balance fluids and electrolytes in your body. In this case, rapid means less than 2 days.”(Silberberg) In Acute renal failure, there are 3 different causes: Pre-renal, intrarenal, and post-renal. In pre-renal, it ” occurs when a sudden reduction in blood flow in the kidney (renal hypo-perfusion) causes a loss of kidney function. “ (Thompson) (WebMD) According to WebMD, there is nothing actually wrong with the kidney in this case and it is also the most common cause of acute renal disease....

- Acute Renal Failure is when the kidneys abruptly stop functioning by excreting wastes of the body. 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. There are many factors that can cause a person’s kidneys to stop working properly. A prerenal cause is something that occurs in the bloody supply to the kidneys, such as inadequate blood profusion to the kidneys.... [tags: Disease/Disorders]

- 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. Symptoms of acute renal failure may include, little or no urine when urinating, swelling in the legs and feet, not feeling like eating, nausea and vomiting, feeling confused, restless, sleepy or anxious, or pain in the back below the rib cage....

- Acute Renal Failure Problem: A man arrives at a clinic with complaints of asthenia, malaise, headache, weight gain, and a decrease in urination. A tentative diagnosis of acute renal failure is made. The generic term for an abrupt and sustained decrease in renal function is called acute renal failure. This is the retention of urea, creatinine, and waste products. Prerenal, intrarenal and postrenal are sub classification for acute renal failure. Prerenal is the most common form of kidney failure.... [tags: kidney disease]
