Stability of Renal Function in Spite of Low Glomerular Filtration Rate: A Case Report

INTRODUCTION: Chronic renal dysfunction is a progressive and irreversible process in kidney function, which often resulted in chronic kidney disease (CKD) or chronic renal failure (CRF). Range of CKD is varying from proteinuria and renal failure to CRF. CASE PRESENTATION: A 78-year-old man presented with stage 4 CKD for 7 years; the glomerular filtration rate (GFR) and creatinine levels remained constant despite no change in his weight. CONCLUSIONS: Although our patient had CKD stage 4, but his condition has not deteriorated and remained constant and stable for several years only by control of blood pressure and usual treatment which prescribed for patients at this stage
