Patients with critical illness often have renal dysfunction, either primary or secondary, that can both complicate and prolong their medical management. Therefore, an understanding of normal renal physiology can help recognize the process or processes that caused the renal dysfunction, and determine the most appropriate corrective and supportive care. The kidney has many important roles other than just urine production. The impact of kidney disease is often predictable. The kidney plays a critical role in fluid and electrolyte balance via many specialized transmembrane pathways. The kidney is also involved in the production and modification of two key hormones and one enzyme. Understanding normal renal physiology can help determine clinical management.This chapter summarizes the important aspects of renal physiology relevant to those who work in a critical care environment.
