Abstract :Aim: We aimed to investigate the correlation between the temporal changes of computed tomography severity score insert ignore into journalissuearticles values(CT-SS); ​​and mean renal parenchymal attenuation insert ignore into journalissuearticles values(MRPA); values in consecutive chest computed topographies insert ignore into journalissuearticles values(CT);. Material and Method: This retrospective, single-center study included 65 insert ignore into journalissuearticles values(≥18 years); COVID-19 patients with positive RT-PCR tests. A radiologist calculated three consecutive chest CT-SSs and measured the MPRAs on CTs from the upper half of each kidney included in the cross-section. Paired samples test and Wilcoxon signed-rank test were used to evaluate the temporal changes of mean renal parenchymal attenuation insert ignore into journalissuearticles values(RPA); and median CT-SS values, in three consecutive CTs. Spearman\`s test was used to evaluate the correlation of each RPA and CT-SS value on three consecutive CTs. Results: The study population included 65 patients with a mean age of 61.49±13.91 years. A total of 36/65 insert ignore into journalissuearticles values(55.4%); were male. We found a significant increase between the first and second CT-SS insert ignore into journalissuearticles values(p<0.001); values, and a significant decrease between the first and second RPA insert ignore into journalissuearticles values(p<0.001); values. There were statistically significant moderate negative linear correlations between MRPA values and consecutive CT-SSs in COVID-19 patients insert ignore into journalissuearticles values(correlation coefficient [r]1=-0.320, p=0.009; r2=-0.381, p=0.002; r3=-0.393, p=0.001);. Conclusion: The decrease in renal parenchymal attenuation in non-enhanced computed tomography is related to the severity of pneumonia in COVID-19 patients and may be an attention factor for acute kidney injury.
