Evaluating Urea and Creatinine Levels in Chronic Renal Failure Pre and Post Dialysis: A Prospective Study

Chronic renal failure is the progressive loss of function of kidney and patient requires a long treatment in the form of renal replacement therapy. Haemodialysis is one of the renal replacement therapy, during which body’s waste products, including creatinine, urea and excess water, are removed. The current study was designed to investigate the impact of haemodialysis on the removal of excess body waste and hemoglobin level of patients. Seventy patients were randomly analyzed. 53% of patients had serum urea level above 200 mg/dl but after dialysis and 66% of patients had urea level below 200 mg/dl. Concerning serum creatinine, 57% of patients had values between 7-12 mg/dl before dialysis, whereas after dialysis in 58% of patients the values were reduced below 7 mg/dl.
