Abstract

Renal failure is the most important disease that causes losing in the efficiency of kidney and is renal failure or may called end stage kidney disease where capacity for kidney become 15% less than the normal levels .This disease can be classified into two types : first (acute kidney failure ) which may resolve and it rapidly developed .Second (chronic kidney failure) : it slowly developed and may become a permanent condition Symptoms of Renal failure include vomiting; swelling in the legs; a loss of appetite; confusion and tiredness. Several complications occurred which include high blood potassium ; volume overload and uremia in acute condition while high blood pressure; anemia and heart disease in the chronic condition. There are several factors that may lead to the progress of acute renal failure conditions such as hypotension, a blockage of the urinary tract, hemolytic uremic syndrome and some medications.While diabetes ,hypertension, polycystic renal disease and nephrotic syndrome represent the major causes of chronic renal failure . Signs that help in identification of acute and chronic renal failure based on mishmash of several factors and help in distinguish between its types such as increasing of creatinine levels and decreasing of urine production are the signs of acute failure while decrease the rate of glomerular filtration to below of 15 or therapy with renal replacement are the signs of chronic renal failure. Acute failure can be treated depending on the main causes , on the other hand may use dialysis (hemodialysis or peritoneal dialysis) or kidney transplant in order treating chronic failure.
