Renal creatinine handling is basically the result of its glomerular filtration and proximal tubular secretion. However, creatinine reabsorption has been documented in certain conditions, such as premature babies, newborns, and healthy elderly people. Additionally, it is known that there is an increase in the proportion of secreted creatinine in chronic renal disease. In this paper, we report our studies on the characteristic reabsorption pattern of creatinine in the elderly with chronic renal disease. Material&Method We studied twenty-seven volunteers with chronic kidney disease, eleven of whom were young and the rest were very old (age
