Factors determining outcome of acute renal failure patients.

OBJECTIVE Acute Renal Failure (ARF) is a common medical problem. Delay in diagnosis is associated with increased mortality. Variety of conditions can lead to ARF. Many factors can influence the outcome of ARF. This study was done to find the predictive factors related to outcome of ARF. METHODS One hundred adult patients of acute renal failure admitted to Ziauddin Hospital were studied. Certain factors related to outcome of ARF were identified and analyzed. RESULTS Among such factors oliguria, levels of urea, creatinine and potassium were found significant poor prognostic predictors on univariate analysis as far as outcome of treatment modality is concerned. The multivariate analysis revealed that the presence of oliguria is the only significant independent predictor (P<0.001) for good outcome with dialysis. CONCLUSION Oliguria was found to be the major predictor of non recovery of renal function.
