Acute Renal Failure
The kidneys is the fundamental organ that is largely responsible for maintaining homeostasis by controlling blood pressure, regulating electrolytes pH balance, manufacturing hormones, formation of processing waste to the urine and eliminating any toxic minerals, excess salts, or protein waste. With that said, without adequate blood perfusing through the kidney, it can cause obstructions in the urinary flow that will damage the kidney tissue. A disorder that may occur suddenly is known as, acute renal failure, in which the causes are divided into three categories: prerenal, intrarenal, and postrenal.
Prerenal failure is one of the most developed causes of kidney failure in patients who are hospitalized. Most conditions, such as burns, long-term vomiting, bleeding, dehydration results in a decrease amount of blood flow to the kidney. Due to blockage or tightening of blood vessel carrying blood to the glomerular filtration rate, this may complicate fluid and electrolytes and result in excess fluid volume. According to Best Practice & Research (2007), “it may lead to ischemic tubular necrosis when the reduction in blood flow is sufficient to result in the death of tubular cells.” However, without sufficient fixation to prerenal failure, it may result in the next stage of intrarenal acute kidney failure.
In intrarenal acute kidney failure, ARF happens when there is
