  2. Glomerular filtration rate - Wikipedia

    en.wikipedia.org/wiki/Glomerular_filtration_rate

    A major measure of kidney function is the glomerular filtration rate (GFR). The glomerular filtration rate is the flow rate of filtered fluid through the kidney. The creatinine clearance rate (CCr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR.

  3. Assessment of kidney function - Wikipedia

    en.wikipedia.org/wiki/Assessment_of_kidney_function

    The Glomerular filtration rate (GFR) is regarded as the best overall measure of the kidney's ability to carry out these numerous functions. An estimate of the GFR is used clinically to determine the degree of kidney impairment and to track the progression of the disease. The GFR, however, does not reveal the source of the kidney disease.

  4. Glomerular hyperfiltration - Wikipedia

    en.wikipedia.org/wiki/Glomerular_hyperfiltration

    Diagram showing a schematic nephron and its blood supply. Glomerular hyperfiltration is a situation where the filtration elements in the kidneys called glomeruli produce excessive amounts of pro-urine. It can be part of a number of medical conditions particularly diabetic nephropathy (kidney damage associated with diabetes).

  5. Chronic kidney disease - Wikipedia

    en.wikipedia.org/wiki/Chronic_kidney_disease

    1.2 million (2015) [6] Chronic kidney disease (CKD) is a type of long-term kidney disease, in which either there is a gradual loss of kidney function which occurs over a period of months to years, or an abnormal kidney structure (with normal function). [2][5] Initially generally no symptoms are seen, but later symptoms may include leg swelling ...

  6. Renal blood flow - Wikipedia

    en.wikipedia.org/wiki/Renal_blood_flow

    Renal blood flow. Renal blood flow. MeSH. D012079. In renal physiology, renal blood flow (RBF) is the volume of blood delivered to the kidneys per unit time. In humans, the kidneys together receive roughly 20 - 25% of cardiac output, amounting to 1.2 - 1.3 L/min in a healthy adult. [1] It passes about 94% to the cortex.

  7. Kidney failure - Wikipedia

    en.wikipedia.org/wiki/Kidney_failure

    Kidney failure, also known as 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] Kidney failure is classified as either acute kidney failure, which develops rapidly and may resolve; and chronic kidney ...

  8. Filtration fraction - Wikipedia

    en.wikipedia.org/wiki/Filtration_fraction

    In renal physiology, the filtration fraction is the ratio of the glomerular filtration rate (GFR) over the renal plasma flow (RPF). Filtration Fraction, FF = GFR/RPF, or . The filtration fraction, therefore, represents the proportion of the fluid reaching the kidneys that passes into the renal tubules. It is normally about 20%.

  9. Loop diuretic - Wikipedia

    en.wikipedia.org/wiki/Loop_diuretic

    A secondary effect of loop diuretics is to increase the production of prostaglandins, which results in vasodilation and increased blood supply to the kidney. [8] [9] Prostaglandin-mediated vasodilation of preglomerular afferent arterioles increases the glomerular filtration rate (GFR) and facilitates diuresis.
