Renal functional reserve (RFR) is described as the difference between a glomerular filtration rate (GFR) measured at baseline and after protein stimulation. The percent change in GFR after a protein load varies based on differences in experimental conditions, with the use of an oral meat protein stimulus and a creatinine clearance method to quantify GFR showing the greatest RFR. A decline in RFR has been found in numerous patient groups. Recent investigations have suggested that a lower RFR may be associated with an increased risk of acute kidney injury and eventual chronic kidney disease.
肾功能储备(RFR)被描述为在基线和蛋白质刺激后测量的肾小球滤过率(GFR)之间的差异。GFR 在蛋白质负荷后的变化百分比因实验条件的不同而有所不同,使用口服肉蛋白刺激物和肌酐清除率方法来定量 GFR 显示出最大的 RFR。在许多患者群体中发现 RFR 下降。最近的研究表明,较低的 RFR 可能与急性肾损伤和最终慢性肾脏病的风险增加有关。
