Several different methods for measuring glomerular filtration rates (GFRs) have been developed in search of a more accurate and simplified technique. Currently, the main methods used are the slope-intercept and distribution volume techniques. In this work, 2922 GFR studies have been retrospectively reanalysed as two- and single-blood sample methods and compared with the three-blood sample data.

Measurement of glomerular filtration rate from a single blood sample using filtration markers may be based on empirical or model-based formulae. The former do not require a whole body metric but are s...
To compare the accuracy of various equations for estimating glomerular filtration rate.
Bedside estimates of renal function are essential for clinical practice in the modern era and have largely relied on serum creatinine concentrations despite the known drawbacks associated with this ch...
Our previous study demonstrated that the cystatin C-based chronic kidney disease (CKD)-EPI equation and combined by serum creatinine (CKD-EPIscr-cys) had better capability to accurately evaluate glome...
To evaluate the relationship between the apparent diffusion coefficient (ADC) values of renal parenchyma and estimated glomerular filtration rates (eGFR).
Our objective is to monitor glomerular filtration rate (GFR)during the perioperative phase of patients undergoing robotic surgery for rectum or large bowel cancers. We will use both a sing...
Aim of the present study is to determine whether 1. RRI can predict glomerular hyperfiltration; 2. glomerular hyperfiltration is associated with low renal resistive index; 3...
Polycystic kidney disease (ADPKD) is a common genetic disorder, characterized by the formation of cysts in the kidneys, causing gradual renal function-loss. Previous studies have shown tha...
Main objective is to investigate the measured glomerular filtration rate (mGFR) as assessed by iohexol clearance in healthy male normovolemic subjects after oral administration of single ...
Estimation of Glomerular Filtration Rate (GFR) is the primary test used to assess patients with renal disease. Although serum creatinine based GFR and nuclear medicine based estimations ar...
A specialized barrier in the kidney, consisting of the fenestrated CAPILLARY ENDOTHELIUM; GLOMERULAR BASEMENT MEMBRANE; and glomerular epithelium (PODOCYTES). The barrier prevents the filtration of PLASMA PROTEINS.
The volume of water filtered out of plasma through glomerular capillary walls into Bowman's capsules per unit of time. It is considered to be equivalent to INULIN clearance.
A clinicopathological syndrome or diagnostic term for a type of glomerular injury that has multiple causes, primary or secondary. Clinical features include PROTEINURIA, reduced GLOMERULAR FILTRATION RATE, and EDEMA. Kidney biopsy initially indicates focal segmental glomerular consolidation (hyalinosis) or scarring which can progress to globally sclerotic glomeruli leading to eventual KIDNEY FAILURE.
A severe stage of acute renal insufficiency, characterized by the sudden decrease in GLOMERULAR FILTRATION RATE to less than 15 ml per min, sometime to less than 1 to 2 ml per min. It is usually associated with OLIGURIA; EDEMA; and increase in BLOOD UREA NITROGEN and serum CREATININE concentrations.
The thin membranous structure supporting the adjoining glomerular capillaries. It is composed of GLOMERULAR MESANGIAL CELLS and their EXTRACELLULAR MATRIX.
