Background: Dual-energy computed tomography (DECT) scan has been proposed as an effective modality for determining the chemical composition of renal stone subtypes. Objectives: This study aimed to evaluate and compare the efficacy of DECT in the identification of renal stone type and composition versus biochemical analysis as the gold standard. Results: The DECT scans showed acceptable accuracy in identifying the chemical composition of renal stone subtypes. Based on the comparison of biochemical analysis and DECT results, the accuracy values for cystine, uric acid, and calcium-oxalate stones were 97%, 100%, and 97%, respectively. Conclusion: Based on the present results, DECT could detect pure uric acid, cystine, and calcium-oxalate stone types with high sensitivity. However, for mixed stones, the stone type, directly identified by DECT scan, was not reliable.
