Impact of sUA ≥8.0 mg/dL on renal outcome after contrast-enhanced computerized tomography. (A) percentages of patients with sUA ≥ 8 mg/dL by stage of CKD, Chi-square tests were used to detect the significant differences among all pairs of populations with different stages of CKD, p < 0.001. (B) incidence of post-contrast AKI by stage of CKD. (C) Incidence of emergent hemodialysis within 30 days by stage of CKD. (D) difference of renal events, post-contrast AKI, and emergent hemodialysis with 30 days after contrast-enhanced computerized tomography, between patients with sUA <8 and ≥8 mg/dL. sUA = Serum uric acid. AKI = Acute kidney injury. CKD = Chronic kidney disease.
