A rapid decrease in kidney function was defined as a decrease in estimated glomerular filtration rate (GFR) of at least 以后每4个月.肾脏功能的快速减退被界定为一种评估肾小球滤过率(GFR)的下降，至少为6毫升/每分钟1.73米左右。
In addition, the relationship between the microvasculature of the renal glomerulus and filtration rate are discussed.另外，文章还对肾小球微血管构筑与滤过率的关系进行了讨论。
