The estimation of glomerular filtration rate and effective renal plasma flow based on camera-based methods for diagnostic and prognostic are studied by manually ROIs drawing on dynamic renal scintigraphy. The manually ROIs drawing may reduce the convenience and reliability. This paper proposes a estimation of glomerular filtration rate and effective renal plasma flow based on camera-based metho...

A method for estimating glomerular filtration rate (GFR) has been developed that is based on an analysis of the total area under the plasma radioactivity-time curve after a single intravenous injection of [125I]iothalamate. Glomerular filtration rates obtained by this method (method A) and those obtained with two widely used single-injection techniques, the slope-intercept method (method B), a...

OBJECTIVES This meta-analysis aimed to perform a systematic review on comparing the diagnostic value of serum cystatin C and creatinine for glomerular filtration rate in renal transplant patients. METHODS The data was extracted into 2×2 table after the articles were assessed by the tool of QUADAS and heterogeneity analysis. The SROC curve and meta-analysis were performed by MetaDisc1.4. RES...

background: hypertension is one the most common causes of chronic kidney disease (ckd). one of the major concerns in hypertensive patients is early detection of renal disorders. in the past, serum creatinine (scr) concentration was used as a marker of kidney function, but it proffers a late reflection of reduced glomerular filtration rate. cystatin c and neutrophil gelatinase-associated lipocal...

Objective: Measurement of glomerular filtration rate (GFR) is the best determinant in assessment of kidney function for diagnostic and therapeutic purposes. As extremely accurate methods of GFR measurement (i.e. Inulin clearance) are expensive and Time-consuming and due to limitations of the 24 hour urine collection method, some formula have been developed for the GFR measurement. Here we have ...

Objective: An abnormal filtration fraction due to divergence between glomerular filtration rate (GFR) and effective renal plasma flow (ERPF) may lead to different estimations of absolute renal function, depending on the radiopharmaceutical administered. The purpose of this study was to estimate GFR and ERPF by measuring the clearances of technetium-99m diethylenetriamine pentaacetic acid (99mTc...

BACKGROUND Impaired glomerular function is one of the health problems affecting childhood cancer survivors (CCS). It is unclear whether glomerular function deteriorates or recovers. We investigated time trends and predictors of glomerular function in CCS. METHODS We evaluated repeated observations of estimated glomerular filtration rate (GFR) and glomerular dysfunction (GFR <90 mL/min/1.73 m(...

With the introduction of combined active antiretroviral therapy and the improved survival of HIV-infected patients, degenerative diseases and drug toxicity have emerged as long-term concerns. We studied the prevalence of decreased glomerular filtration rate (GFR) and associated risk factors in a cohort of HIV-infected patients from a middle-income country. Our cross-sectional study included all...

OBJECTIVE To characterize the pharmacokinetic disposition of carboplatin and determine whether glomerular filtration rate (GFR) could be used to predict carboplatin clearance and myelotoxic effects in cats with tumors. ANIMALS 10 cats with tumors. PROCEDURE Glomerular filtration rate was assessed in each cat by monitoring plasma clearance of technetium Tc 99m-labeled diethylenetriaminepenta...
