title: Etiology of acute renal failure in a tertiary center.
abstract: Acute renal failure (ARF) occurs commonly in developing countries. Our aim was to assess the etiologies and outcomes of ARF in a tertiary care hospital in Pakistan and compare them with data from developed and developing countries. All patients admitted to the Aga Khan University Hospital, Karachi from January 1991 to December 2000 fulfilling the criteria of acute renal failure were reviewed retrospectively. Acute renal failure for the purpose of this study was defined as persistent elevation of serum creatinine to above 2 mg/dL (177 umol/L) on two consecutive occasions despite correction of any abnormal hemodynamic or mechanical factors. We studied 898 patients fulfilling the criteria of ARF, 61% (551) were males, and the mean age was 53% +/- 17.6 (range 15-91) years. Medical causes accounted for (88%) of ARF cases and surgical causes for (11%). Majority of the patients had pre-renal ARF, and 5% had drug related ARF. The base line creatinine was 1.9 +/- 1.8 mg/dL, while 27% of the patients had pre-existing chronic kidney disease. The mean rise in creatinine was 7.18 +/- 3.8 mg/dL. We conclude that ARF resulted from pre-renal etiologies in majority of the patients and early recognition and management may improve the prognosis of these potentially preventable causes.
