Scientists report new approach to reduce or prevent renal fibrosis

Renal fibrosis, the abnormal accumulation of fibrotic material within the kidney, hinders kidney function and may lead to eventual renal failure. Using genetically altered mice, researchers from Duke University investigated ...

Is kidney failure a man's disease?

A new analysis of the ERA-EDTA Registry reveals a striking gender difference in the incidence and prevalence of end-stage renal disease. Two thirds of all dialysis patients in Europe are male. It seems beyond hormonal effects ...

Renal function

Renal function, in nephrology, is an indication of the state of the kidney and its role in renal physiology. Glomerular filtration rate (GFR) describes the flow rate of filtered fluid through the kidney. Creatinine clearance rate (CCr) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR. Both GFR and CCr may be accurately calculated by comparative measurements of substances in the blood and urine, or estimated by formulas using just a blood test result (eGFR and eCCr).

The results of these tests are important in assessing the excretory function of the kidneys. For example, grading of chronic renal insufficiency and dosage of drugs that are primarily excreted via urine are based on GFR (or creatinine clearance).

It is commonly believed to be the amount of liquid filtered out of the blood that gets processed by the kidneys. Physiologically, these quantities (volumetric blood flow and mass removal) are only related loosely.
