American Nephrology Nurses Association

Nephrology (from Ancient Greek νεφρός (nephrós), meaning "kidney", and λόγος (lógos), meaning "study") 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 replacement therapy (dialysis and kidney transplantation). The word "renal" is an adjective meaning "relating to the kidneys", and its roots are French or late Latin. via Wikipedia ↗
