Correlation of 2 Hours and 24 Hours Creatinine Clearance in Renal Donors After Unilateral Nephrectomy

Conjugated linoleic acid rat pretreatment reduces renal damage in ischemia/reperfusion injury: Unraveling antiapoptotic mechanisms and regulation of phosphorylated mammalian target of rapamycin

“…Experimental methods for these tests are described elsewhere . Creatinine clearance (C Cr ) as an indicator of glomerular filtration rate and fractional sodium excretion (FE Na ) as an indicator of proximal tubule function were calculated as has been described previously .…”

Urinary potassium excretion and its association with acute kidney injury in the intensive care unit

“…The total amount of urinary potassium excreted in 2-hours was calculated by multiplying the 2-hour urine sample potassium concentration (mmol/l) by the urine volume (litres in the 2 hours collection period) to give mmol of potassium excreted in 2 hours. We chose a 2-hour urine collection period for this study because of previous studies, including one on ICU patients, have shown that it correlates well with the calculated CrCl over a 24-hour period [15,16].…”

Evaluation of the Urinary Kidney Injury Molecule-1 Levels in Patients With Diabetic Nephropathy

“…Creatinine clearance (CrCl) was used as a measurement of GFR. To estimate the CrCl, 24 hours urine samples were collected and CrCl was calculated using a standard formula [16]: (CrCl=(U*V)/(P*t); U=urine creatinine, P= plasma creatinine, V= volume of urine during 24 hours period, t= duration of which urine was collected. NKF/DOQI guidelines were used to define CKD stages [2]: the patients with GFR of 60-90 ml/min were defined as stage 2, 30-60 ml / min were defined as stage 3 and 15-30 ml/min were defined as stage 4 CKD [2].…”
