Estimation of the 24-h urinary protein excretion based on the estimated urinary creatinine output

摘要

The urinary protein/creatinine ratio Up/Ucr (g/gCr) has been used in the clinical management of patients with chronic kidney disease (CKD). However, a discrepancy is often noted between the Up/Ucr and 24-h urinary protein excretion 24hUp (g/day) in patients with extremes of muscle mass. We examined devised a method for precise estimation of the 24-h urinary protein excretion (E-24hUp) based on estimation of 24-h urinary creatinine output (E-24hCr).
