Literature data and original experience are reviewed on the treatment of alimentary toxoinfections complicated with acute renal failure (ARF). Out of 192 patients prerenal ARF was recorded in 74.5%, renal in 25.5% of the cases. ARF resulted from hemodynamic disturbances, salt and water loss, intoxication. ARF clinical symptoms were poor, the patients developed decompensated metabolic acidosis and hyperazotemia. Pathological and histological evidence is available for 17 patients with "shock kidney". They died of infective toxic shock. The treatment of ARF complicating acute alimentary toxoinfections in 98.9% made a success if implied polyion crystalloid solutions. Hemodialysis was demanded in 1.1% of the cases.
