Kidneys perform an important function for the body. These help in filtration of the blood so as to remove all the wastes, toxins and chemicals from it which can then be eradicated from the body via urine. This task is performed by the small structural and functional units called as nephrons in the kidneys. Due to malfunctioning or obstructions in the working of these nephrons, the process of filtration of the wastes from the body is also affected adversely. Consequently, the wastes are not removed from the body and these keep on accumulating in the body and start entering the blood stream again. This condition is then referred to as kidney failure or renal failure. Due to entry or presence of the wastes in the blood stream, the health of the vital organs of the body is also affected in a negative manner. It is to be noted that the condition of kidney failure or renal failure may arise within few hours or even in few days. If not treated properly and well-in-time, it may even prove to be fatal for the sufferer. People who possess good health may recover from this condition in short span of time.
