Recovery from acute renal failure.
Acute tubular necrosis is the most common cause of acute renal failure making up two-thirds of such cases. Mortality is best correlated to basic disease. Surgery, particularly in the abdomen, carries an unusually sinister prognosis. The influence of age on outcome is controversial. Intensified dialysis, early reoperations, hyperalimentation, and possibly continuous dialysis and antibiotic barrage deserves close investigation as tools of improving survival. Almost all surviving patients recover renal function within 30 days and beyond two months recovery almost never occurs. Approximately 3% of the patients initially suspected of having acute tubular necrosis will need chronic hemodialysis indefinitely or have a transplant to regain renal function. The older patient seems to be more susceptible to this problem. Delayed recovery and chronic renal failure is unusual. High dose loop diuretic therapy and hyperalimentation with intravenous amino acids may shorten the time for recovery, although considerable controversy exists.
