    summary Objectives: to determine whether the thickness of the cortical renal (EC) ultrasound Shows a good linear correlation with the glomerular filtration rate (GFR) in With and without chronic kidney disease (CKD), as well as Sensitive, specific and accurate cutoff value to define the CKD through this Using the GFR as a reference. Methods: the study took place in two We performed renal ultrasonography in 45 non-CKD patients (GFR ? 60 ml / min) And we used data from 48 patients with CKD (GFR <60 ml / min) from a previous study Carried out by the same group, 4 years ago. The patients in this phase were screened from a Spontaneous demand. The renal morpho-structural parameters evaluated were Bipolar diameter (DBP), parenchyma (PE) thickness and EC. The GFR was calculated by Cockcroft Gault formula. The linear correlation coefficient (r) was calculated for To establish whether there was a relationship between the various renal measures and the GFR, A cut-off value was established to define DRC using EC. Results: The EC Mean in the left middle third of the non-CKD group was 0.96 ± 0.15 In the group with CKD, data obtained in the first phase of the study, this value was 0.68 ± 0.12 cm (maximum value: 1.14 cm / minimum value: 0.37 cm). Conclusion: We found a moderate positive correlation force between the GFR and the CE of the third Mean of the left kidney (r = 0.626, p <0.0001) in patients with and without CKD. The EC Presented sufficient accuracy and equated to the other parameters to define the CKD. The intersection of EC and DBL + PE increased sensitivity and specificity in Detection of DRC.
