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 ...

BACKGROUND AND OBJECTIVES Measurement of GFR is important for the management of chronic kidney disease (CKD). Although bolus administration of radiocontrast agents is commonly used to measure GFR, the optimal duration of sampling to assess their plasma clearance is unknown. The purpose of this study was to evaluate whether the duration of plasma sampling influences precision and estimation of G...

Aim The inorganic anions nitrate and nitrite are oxidation products of nitric oxide (NO) that have often been used as an index NO generation. More than just being surrogate markers NO, nitrate/nitrite can recycle to bioactive again. Nitrate is predominantly eliminated via the kidneys; however, there less knowledge regarding tubular handling. aim this study, part a large randomized controlled tr...

BACKGROUND AND OBJECTIVES Estimation of GFR in children from serum creatinine measures in regional databases is limited by a lack of height data. Furthermore, the ability of GFR estimating equations to quantify changes in GFR over time is unknown. Two methods of estimating GFR when height is unknown and the ability of several GFR equations to quantify GFR changes over time were evaluated. DES...

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...

BACKGROUND MicroRNAs (miRs) are small non-coding RNAs that are important regulators of gene expression and have been implicated in atherosclerosis. Kidney injury distal to atherosclerotic renal artery stenosis (ARAS) is aggravated by atherosclerosis. Therefore, this study tested the hypothesis that renal miR expression would be altered in patients with ARAS. METHODS Patients with essential hy...

BACKGROUND Proenkephalin (pro-ENK), a stable and reliable surrogate marker for unstable enkephalins, was found to be associated with acute kidney injury and chronic renal failure in previous studies. We aimed to investigate whether pro-ENK is linked to chronic kidney injury and poor long-term outcome in renal transplant recipients (RTR). METHODS We included 664 stable RTR and 95 healthy kidne...
