We measured the CT values of stones using a 64-slice spiral CT scanner and evaluated the stone composition and fragility.Results: In this study, the stone compositions were calcium oxalate (61.5%), calcium phosphate (15.4%), calcium oxalate and calcium phosphate mixture (15.4%), and uric acid (7.7%). The average CT value of calcium oxalate stones was the highest (926.67±223.48 HU), while that of uric acid stones was the lowest (347.5±7.07 HU). The average CT value of fragile 精品文档---下载后可任意编辑stones (352.50±59.44 HU) was lower than that of non-fragile stones (950.63±230.21 HU).Conclusion: This study suggests that measuring the CT values of urinary tract stones using 64-slice spiral CT can predict stone composition and evaluate stone fragility. This technique can provide important reference for doctors in treatment plan selection and surgical guidance.Keywords: urinary tract stone, CT scan, stone composition, fragility, 64-slice spiral CT
