Acute renal failure in a teaching hospital.

This was a retrospective study of the clinical course of 164 adult inpatients with acute renal failure (ARF) at the Hospital of the University of Science Malaysia admitted from June 1986 to May 1990. The mean age was 49.8 +/- 17.2 years. 33.5%, 54.9% and 11.6% were surgical, medical and obstetrical patients respectively. Obstructive uropathy, poor cardiac output or decrease in intravascular volume and infection accounted for more than 67% of the cases. Acute renal failure was present at admission in 113 (69%) patients. The majority of the patients (80%) had nonoliguric acute renal failure with daily output of urine of more than 400 ml. Compared with nonoliguric patients, oliguric patients had higher mortality (56.3% vs 18.9%, p < 0.01), and needed dialysis more frequently (43.8% vs 12.9%, p < 0.01). Early recognition of acute renal failure, improvement in early treatment of renal stones and discerning use of nephrotoxic drugs could result in decrease in incidence and severity of renal failure.
