AKI, decline in blood urea nitrogen
Patients selected for this study carry a very high risk to develop AKI upon exposure to radiocontrast. According to the risk score proposed by Mehran et al. [Demographic and baseline laboratory data of the studied patients were summarized in Following the administration of renoprotective medications, the distinct groups showed a slight improvement in kidney function tests. The improvement in serum urea was the most evident in all groups and was most pronounced in group 4. Here, the percentage of decline in blood urea nitrogen was significantly greater than in the other three groups. The improvement in serum creatinine was the least in group 2, while the improvement in the glomerular filtration rate was maximal in group 3. On the other hand, a maximal antiproteinuric effect was observed in group 4 (
