Abstract
Acute renal failure is life-threatening situation associated with severe metabolic pathology rarely presented with uremia. Causes could be pre-renal (insufficient blood supply), renal (renal parenchyma pathology) or post-renal (urinary tract obstruction).
Acute situation usually needs acute haemodialysis. It is mandatory to set urinary diversion in case of urinary tract obstruction presence immediately.
It is necessary to minimize warm ischemia time during nefron-sparing procedures on renal parenchyma as the acute tubular necrosis prevention.
