Method: cross - sectional prospective study Results (1) glycemie had negative correlation with predicted GFR of Cockcroft Gault in the normal glycemia group (r= - 0, 36, p<0, 05) and had no correlation with predicted GFR of Cockcroft - Gault in the hyperglycemia group (r=-0, 13, p>0, 05), (2) HbA1C had negati ve correlation with predicted GFR of Cockcroft - Gault in both the normal glycemia group and the hyperglycemia group (r=-0, 35, p<0, 05).
