In the condition when a person is suffering from the acute renal failure, out of the blue, he will face the deterioration in renal function. Most of the time, this deterioration in the renal function is reversible for which the period of a few of days or weeks is required but there are some cases in which this problem is permanent. The process of this reversal is accompanied by a reduction in urine volume. Quite the opposite, if a person is suffering from the chronic renal failure then it is confirmed that he/she has various sorts of the clinical syndromes. These medical conditions are mainly consists of the metabolic and systemic consequences of a gradual but extensive and irreversible lessening in the excretory and homeostatic functionalities of the kidneys of that person. The process of CRF can never be overturned. The medical condition in which the kidneys of the patient fail to perform their proper functionality is known as renal failure. In this situation, the kidneys of the tolerant don’t sufficiently filter the waste products from his/her blood. There are two main types of renal failure called Acute and Chronic Renal Failure. The major difference between these two kinds of renal failure is presented here.

Acute Renal Failure

A person is said to have the acute renal failure in the case when he faces the problem of suddenly diminution in the glomerular filtration rate that is generally known as (GFR). The procedure of this problem completed within a few days or weeks. After diagnosing of ARF, if a person shows an increase in his serum creatinine that must be greater than 50 micro mol / L then this is the condition of ARF. Otherwise, an increase in serum creatinine that is greater than 50% from the baseline or the decrease in calculated creatinine clearance is greater than 50% will also show ARF and the patient is suggested to utilize the treatment of dialysis. In general, the patient of the ARF shows a number of warning signs particularly at the time when ARF is present in him in the early stages.

The later stages of the ARF will may present a drop in the urinary volume and features of intra vascular volume depletion as well. The major causes of the ARF are understandable such as gastrointestinal bleeding, burns, skin disease, and sepsis. There are lots of other causes of ARF that can be hidden such as like secret blood losses that may be occurred in shock to the abdomen. The patient of the ARF often shows the features of metabolic acidosis and hyperkalaemia.  After the completion of the clinical diagnosis is done, the patients are taken for further investigated by taking urinary full report, electrolytes, serum creatinine and imaging. Use of Ultra sound is also vital because from this scan, the swollen kidneys and reduced cortico-medullary demarcation will come in front of you. The management of ARF is the demand of the day for which the process of the recognition and treatment of life-threatening complications, including the hyperkalaemia and the pulmonary oedema. The severity of the underlying disorder and the other complications are the forecast of the acute renal ARF.

Chronic Renal Failure

When the one of the kidneys is damaged or a decreased glomerular filtration is shown the rate of which will be less then 60ml / min / 1.73m2 for at least 3 or more months as compared to ARF then it is said that the patient is suffering from the Chronic Renal Failure. The symptoms of the CRF usually come to view without prior notice, or within a short time. Among all the major causes of CRF, the most common one is known as the chronic glomerulonephritis together with the condition of ever increasing number of diabetic nephropathy in the patient. But there are other reasons for CRF are present consisting of the chronic pyelonephritis, connective tissue disorders, polycystic kidney disease, and amyloidosis. From the clinical point of view, the patients demonstrate a number of specific things which include the malaise, anorexia, itching, vomiting, convulsions and more like that. After utilizing the scan of the Ultra sound on the CRF patient, small sized kidneys will be shown in addition to the reduced cortical thickness and the amplified echogenecity. The renal size of the patient may remain normal. Every forecast related to the CRF patient will come to one point that is death. The cure for this disease is the renal replacement therapy that will increase the survival but on the other hand, the patient will never live a normal life.

Key Differences between Acute Renal Failure and Chronic Renal Failure

  1. The impairment of renal function occurs sudden or within a short period of time that may be consist of some days to weeks be the ARF. The CRF can be diagnosed if more than 3 months are passed.
  2. There is a great chance that the ARF is reversed while there is no hope for CRF reversing.
  3. The major cause of ARF is hypovolaemia while the main causes of the CRF are chronic glomerulopathy and diabetic nephropathy.
  4. The output of the urine will be reduced in the acute renal failure patients. The constitutional symptoms or its long term complication are present in the chronic renal failure patients.
  5. CRF is continues process while the acute renal failure patients are characterized in the medical emergency.
  6. The forecast of the CRF is worse than that of ARF.
