Prompt treatment of some causes of azotemia can result in restoration of kidney function; delayed treatment may result in permanent loss of renal function. [ipfs.io]

Treatment The goal of treatment for prerenal azotemia is to restore normal blood flow to the kidneys. Time is of the essence in this treatment, as permanent kidney damage could result from the loss of blood if it continues for too long. [kidneypedia.net]
