Kidney failure, also known as renal failure or end-stage renal disease (ESRD), is a medical condition in which the kidneys can no longer adequately filter waste products from the blood, functioning at less than 15% of normal levels. [2]
The medical history takes into account present and past symptoms, especially those of kidney disease; recent infections; exposure to substances toxic to the kidney; and family history of kidney disease. Kidney function is tested by using blood tests and urine tests. The most common blood tests are creatinine, urea and electrolytes.
Nephrology (from Ancient Greek nephros 'kidney' and -logy 'the study of') is a specialty for both adult internal medicine and pediatric medicine that concerns the study of the kidneys, specifically normal kidney function (renal physiology) and kidney disease (renal pathophysiology), the preservation of kidney health, and the treatment of kidney disease, from diet and medication to renal ...
Risk factors for kidney disease include diabetes, high blood pressure, family history, older age, ethnic group and smoking. For most patients, a GFR over 60 (mL/min)/(1.73 m 2) is adequate. But significant decline of the GFR from a previous test result can be an early indicator of kidney disease requiring medical intervention.

This illustration demonstrates the normal kidney physiology, including the Proximal Convoluted Tubule (PCT), Loop of Henle, and Distal Convoluted Tubule (DCT). It also includes illustrations showing where some types of diuretics act, and what they do. Renal physiology (Latin renes, "kidneys") is the study of the physiology of the kidney.
Non-infectious diseases of the kidney include acute kidney injury, chronic kidney disease, [185] glomerular diseases [186] and tubular diseases (renal tubular acidosis, Fanconi syndrome and renal glycosuria). [187] In small mammals, renal neoplasms are rare but usually are not benign. [188] Renal neoplasms and abscesses are rare in ruminants. [189]
Acute kidney injury (AKI), previously called acute renal failure (ARF), [1] [2] is a sudden decrease in kidney function that develops within seven days, [3] as shown by an increase in serum creatinine or a decrease in urine output, or both. [4]
