UNUSUAL CASES OF ACUTE TUBULAR NECROSIS

Abstract
The present concept of the pathophysiology, the abnormal laboratory findings, the clinical course and the accepted therapy of acute tubular necrosis is described. One case report stresses that the oliguric phase may be exceedingly short or even absent. The second case indicates that the damaged kidney may excrete a urine with low specific gravity and with very little electrolytes. A finding of great diagnostic significance seems to be the low ratio of urinary to serum urea. The third case presents a therapeutic paradox of the coexistence of hypokalemia and the onset of the oliguric phase of tubular necrosis.
