| Acute renal failure (ARF) is defined as the rapid cessation of renal excretory function within a time of hours or days, accompanied by a rise in serum urea and creatinine, and accumulation of nitrogenous waste products in a patient whose renal function was previously normal. It is usually, but not always, accompanied by a fall in urine output. This study included 40 patients of acute renal failure from both sexes. The biochemical investigations carried were the renal function tests including determination of urea, creatinine, uric acid, sodium and potassium in serum. The results of the present study shows that the levels of urea, creatinine, uric acid and potassium were significantly higher in patients of acute renal failure in comparison with control group, P value was less than 0.05, it also other parameter sodium was non-significantly decreased in patients when compared with control individuals. |
