Intrarenal acute renal failure is the result of damage to kidney tissue. Possible causes of intrarenal acute renal failure are hemolytic uremic syndrome, glomerulonephritis, and pyelonephritis. Prerenal acute renal failure is the result of decreased perfusion to the kidney. Possible causes include dehydration, septic and hemorrhagic shock, and hypotension. Postrenal acute renal failure results from obstruction of urine outflow. Conditions causing postrenal failure include ureteropelvic obstruction, ureterovesical obstruction, or neurogenic bladder. Renal failure caused by hemolytic-uremic syndrome is of the acute nature. Chronic renal failure is an irreversible loss of kidney function, which occurs over months or years.
