Differences between various glomerular filtration rate calculation methods in predicting patients at risk for contrast-induced nephropathy

Contrast Medium-Induced Nephropathy

“…In addition, they are not useful for patients with a glomerular filtration rate above 60 ml min -1 (Stevens et al 2006). Even below this level, they do not always result in the same glomerular filtration rate (Stevens et al 2006;Band et al 2007;Eken and Kilicaslan 2007) (Fig. 3).…”

Nephrogenic Systemic Fibrosis and Gadolinium-Based Contrast Media

“…In addition, they are not useful for patients with a glomerular filtration rate above 60 ml min -1 (Stevens et al 2006). Different methods also can result in very different values for glomerular filtration rate (Stevens et al 2006;Band et al 2007;Eken and Kilicaslan 2007). For example, a 43-year-old 70 kg male patient with a creatinine level of 264 lmol l -1 has a glomerular filtration level of 32 ml min -1 if it is calculated by the Cockcroft-Gault equation.…”

Nephrogenic Systemic Fibrosis

“…Below that level they do not always result in the same GFR. For instance, a 43‐year‐old 70 kg male patient with a creatinine level of 132 μmol/L has a glomerular filtration level of 63 mL/min if it is calculated by the Crockcroft–Gault equation (44–46). However, the same patient will have a glomerular filtration level of 66 mL/min if he is Afro‐American, and 54 mL/min if he is Caucasian, calculated by the MDRD equation.…”
