Background: Evaluation of glomerular filtration rate according to the Cockcroft - Gault formula, MDRD and glomerular filtration rate by radioiodine renal scintigraphy
combining with comparing the difference as well as the significance of each method for glomerular filtration rate measurement. The renal scintigraphy method had clear benefits in the selecting kidney for transphant. Methods: 194 voluntary kidney donation patients at the Department of Hemodialysis were calculated glomerular filtration rate according to the Cockcroft-Gault formula, MDRD and radioiodine injection renal scintigraphy. Cross-sectional, retrospective descriptive method. Research content: Comparing the effectiveness of the evaluation of glomerular filtration rate according to the formulas compared with kidney scintigraphy on voluntary kidney donors. Results: About the glomerular filtration rate according to the estimated formulas and renal scintigraphy. According to the formula Cockcroft - Gault: 99,79 ± 14,72 ml/min/1,73m2. According to the MDRD formula: 87,34 ± 13,10 ml/ min/1,73m2. According to renal scintigraphy method: 128,68 ± 16,15 ml/min/1,73m2. Conclusions: There is a close correlation in glomerular filtration rate between the Cockcroft - Gault formula and MDRD formula, (r = 0,77), p <
0,001. The correlation between these two formulas and renal scintigraphy method is weaker.
