Estimation of Glomerular Filteration Rate (GFR)

چکیده
I. Clearance Methods:The concept of renal clearance was introduced as a way of expressing the relation between the excretion per unit time and the concentration in the plasma which is obviously an index of kidneys ability to clear the blood of any substance (1). Measurements of GFR are traditionally based on the renal clearance of a marker in plasma, expressed as the volume of plasma completely cleared of the marker per unit time. If the marker has no extrarenal elimination, tubular reabsorption or secretion then the clearance is given by the formula.

Introduction:Detecting renal allograft dysfunction early will allow timely diagnosis and treatment. There is no objective recommendation by national kidney societies for glomerular filtration rate (eGFR) estimation in post-transplant setting. 99mTc-DTPA Technetium-99m Diethylene triamine penta acetic acid) renogram can identify early renal dysfunction much before ser...

Cystatin C is a 13 KD basic protein that is a member of the cystatin superfamily of cysteine protease inhibitors. The cystatin C gene seems to be a house keeping gene, which is compatible with a stable production rate of cystatin C by most cells. This protein is freely filtered through the glomerulus and almost completely reabsorbed and catabolized by proximal tubular cells. Because of the...

Background: Acute Renal Failure (ARF) is a common complication in Pediatric Intensive Care Units (PICUs) and its quick diagnosis at the bedside is of utmost importance. Various systems have been introduced for the rapid diagnosis of the condition. One of these systems is RIFLE, which based on Glomerular filteration rate (GFR) and urinary output, ARF patients are divided into 5 categories na...
