It reflects one aspect of kidney function, how efficiently the glomeruli – the filtering units – work. The normal GFR is 90–120 ml/min. The units of creatinine vary from country to country, but since the glomeruli make up <5% of the mass of the kidney, the GFR does not indicate all aspects of kidney health and function.
The normal range of GFR, adjusted for body surface area, is 100–130 average 125 mL/min/1.73m 2 in men and 90–120 ml/min/1.73m 2 in women younger than the age of 40. In children, GFR measured by inulin clearance is 110 mL/min/1.73 m 2 until 2 years of age in both sexes, and then it progressively decreases.
Kidney failure, also known as renal failure or end-stage renal disease (ESRD), is a medical condition in which the kidneys can no longer adequately filter waste products from the blood, functioning at less than 15% of normal levels. [2]
GFR on its own is the most common and important measure of renal function. However, in conditions such as renal artery stenosis, blood flow to the kidneys is reduced. Filtration fraction must therefore be increased in order to perform the normal functions of the kidney. Loop diuretics and thiazide diuretics decrease filtration fraction.
Minimal change disease (MCD), also known as lipoid nephrosis or nil disease, among others, is a disease affecting the kidneys which causes nephrotic syndrome. [1] Nephrotic syndrome leads to the loss of significant amounts of protein to the urine (proteinuria), which causes the widespread edema (soft tissue swelling) and impaired kidney function commonly experienced by those affected by the ...
Diabetic nephropathy, also known as diabetic kidney disease, [5] is the chronic loss of kidney function occurring in those with diabetes mellitus. Diabetic nephropathy is the leading causes of chronic kidney disease (CKD) and end-stage renal disease (ESRD) globally. The triad of protein leaking into the urine (proteinuria or albuminuria ...
In humans, about 20,000 protein coding genes are expressed in human cells and almost 70% of these genes are expressed in normal, adult kidneys. [26] [27] Just over 300 genes are more specifically expressed in the kidney, with only some 50 genes being highly specific for the kidney. Many of the corresponding kidney specific proteins are ...
<25% long-term kidney problems, which for some of these, could include chronic kidney dysfunction or even failure (which could ultimately need dialysis or transplantation to treat); [1] 5% risk of death during the illness in developed countries with treatment: Frequency: 1.5 per 100,000 per year [5] Deaths <5% risk of death [1]
