NONO-LIGURIC ACUTE RENAL-FAILURE

Abstract

The course of nonoliguric acute renal failure (ARF) was analyzed in 11 patients. The possible etiology of the renal failure was multiple in all cases and did not differ from that seen in oliguric acute tubular necrosis (ATN). Other than the urine volume, which ranged from 510-2325 ml/day, there was no major clinical or biochemical difference between these cases of nonoliguric ARF and those described for oliguric ATN. Creatinine clearance was higher than anticipated in oliguric ATN and ranged from 2.8-15.0 ml/min. There was a direct relationship between creatinine clearance and daily urine volume. The essential difference between oliguric and nonoliguric renal failure appears to be the lesser degree of renal damage in the nonoliguric form.
