Acute renal failure can complicate a wide spectrum of disorders, and for the purpose of diagnosis and management is divided according to the mechanism that lead to renal compromise. The three categories are pre-renal [[azotemia]] (diseases that cause renal [[hypoperfusion]]), renal azotemia (diseases directly affecting the renal parenchyma), and post-renal azotemia (diseases affecting the [[urinary tract]] causing [[urinary tract obstruction|obstruction]]).

===According to the levels of renal dysfunction===
Acute renal failure is usually categorised (as in the flowchart below) according to ''pre-renal, renal'' and ''post-renal'' causes.

Overview

Acute renal failure can complicate a wide spectrum of disorders, and for the purpose of diagnosis and management is divided according to the mechanism that lead to renal compromise. The three categories are pre-renal azotemia (diseases that cause renal hypoperfusion), renal azotemia (diseases directly affecting the renal parenchyma), and post-renal azotemia (diseases affecting the urinary tract causing obstruction).
