Renal failure is the condition where the kidneys fail to function properly. Physiologically, renal failure is described as a decrease in the glomerular filtration rate. Clinically, this manifests in an elevated serum creatinine. It can broadly be divided into two categories: acute renal failure and chronic renal failure.

• Chronic renal failure (CRF) develops slowly and gives few symptoms initially. It can be the complication of a large number of kidney diseases, such as IgA nephritis, glomerulonephritis, chronic pyelonephritis and urinary retention. End-stage renal failure (ESRF) is the ultimate consequence, in which case dialysis is generally required while a donor for renal transplant is found.
• Acute renal failure (ARF) is, as the name implies, a rapidly progressive loss of renal function, generally characterised by oliguria (decreased urine production, quantified as less than 400 to 500 mL/day in adults, less than 0.5 mL/kg/h in children or less than 1 mL/kg/h in infants), body water and body fluids disturbances and electrolyte derangement. An underlying cause must be identified to arrest the progress, and dialysis may be necessary to bridge the time gap required for treating these underlying causes.
