title: [Oliguric and non-oliguric renal failure in high risk patient in intensive care units (author's transl)].
abstract: Oliguric and non-oliguric acute renal failure was studied in a group of 28 high risk patients in an intensive care unit. Of these, 15 (53.5%) presented oliguric and 13 (46.4%) non oliguric acute renal failure. Causal agents of the renal failure were postoperative in 14 cases, mainly peritonitis; medical in 10 and posttraumatic in 4. Oliguric renal failure was most commonly medical, while non-oliguric renal failure was predominantly postoperative in origin (p less than 0.05). Results of urinalysis indicative of renal failure were similar in both groups: NAO, osmolarity, FeNa, BUN o/p and creatinine o/p, as were degree and course of renal failure, and the appearance of complications and indications for dialysis. There was no significant difference in mortality rate between oliguric (93%) and non-oliguric (85%) patients; total mortality was 89%. The results of this study clearly show that non-oliguric acute renal failure carries the same poor prognosis in high risk patients in intensive care units as do the oliguric forms of the entity.
