OBJECTIVE The usefulness of estimated glomerular filtration rate may not be restricted to pre-dialysis patients, since we reported that estimated glomerular filtration rate was well correlated with measured total creatinine clearance in peritoneal dialysis patients. To clarify the clinical usefulness of estimated glomerular filtration rate as a parameter for peritoneal dialysis adequacy, we ret...

PURPOSE We used what is to our knowledge a new method to estimate volume loss after partial nephrectomy to assess the relative contributions of ischemic injury and volume loss on functional outcomes. MATERIALS AND METHODS We analyzed the records of 301 consecutive patients who underwent conventional partial nephrectomy between 2007 and 2010 with available data to meet inclusion criteria. Perc...

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: hypertension is more common in adults with type 1 diabetes mellitus (t1dm) than the general population. the aim of this study was to detect the pre-hypertensive stage in children with t1d and to evaluate its correlation with diabetic nephropathy compared to non-diabetic children. methods: this was a prospective cross-sectional study in an out-patient clinic of a university hospital....

context in human beings, uric acid is the poorly soluble circulating end product of the purine nucleotide metabolism. a reduction in the glomerular filtration rate (gfr) contributes to hyperuricemia, which is frequently observed in patients with chronic kidney disease (ckd). evidence acquisition hyperuricemia is defined as a serum uric acid level > 7.0 mg/dl in males and > 6.0 mg/dl in females,...

BACKGROUND The prevalence of chronic kidney disease (CKD) increases with age, and new glomerular filtration rate-estimating equations have recently been validated. The epidemiology of CKD in older individuals and the relationship between a low estimated glomerular filtration rate as calculated by these equations and adverse outcomes remains unknown. METHODS Data from the BELFRAIL study, a pro...

Micropuncture techniques were used to evaluate the determinants of glomerular filtration in hydropenic dogs. Stop-flow and servo-null techniques were used to estimate the glomerular capillary and proximal tubule hydrostatic pressures. The validity of stop-flow estimates was verified by comparisons with direct puncture of glomerular capillaries in Munich-Wistar rats. Efferent arteriolar oncotic ...

Single glomerulus filtration rate in Eptatretus stouti averaged 20.3+/-2.13 (S.E.M.) nl min(-1). Single glomerulus glomerular filtration rate (GFR) could be correlated with arterial pressure when arterial pressure exceeded about 4 cm H2O. Glomerular filtration was affected by postglomerular resistance brought about by alteration of the volume of urinary spaces. Filtration undoubtedly plays a ro...
