CT Diagnosis of Uric Acid Stones in Asymptomatic Patients with Hyperuricemia during Physical Examination
Objective To evaluate CT diagnosis of uric acid stones in asymptomatic hyperuricemia patients.Methods The CT data of 116 asymptomatic patients with hyperuricemia who came to our hospital for health examination from April 2023 to April 2024 were retrospectively analyzed,and dual-energy CT(DE-CT)scans were performed in all of them.Eight participants with uric acid stones confirmed on DE-CT were also included.CT value was compared based on three algorithms(ppLapl-MaxHU,MaxHU,KNN-ppLapl-MaxHU).Results Among 124 asymptomatic patients with hyperuricemia,106 were non-uricolithiasis and 37 were uricolithiasis.The sensitivity,specificity and accuracy of KNN-ppLap1-MaxHU for uric acid and non-uric acid stones were 100％(37/37),97％(103/106)and 98％(140/143),respectively.ppLap1-MaxHU was 95％(35/37),98％(104/106),and 97％(139/143),and MaxHU was 92％(34/37),94％(100/106),and 94％(134/143).Conclusion The accuracy of quantitative single energy CT(SE-CT)(KNN-ppLapl-MaxHU)in the classification of uric acid stones is comparable to that of DE-CT.
