The Application and Diagnostic Value of CT in the Analysis of Chemical Components of Urinary Calculi
Objective:To analyze the application and diagnostic value of electronic computed tomography(CT)in the chemical composition analysis of urinary calculi.Method:A total of 89 patients diagnosed with urinary calculi in Urology Department of Jiujiang NO.1 People's Hospital from May to November 2021 were selected,and a CT scanner were used to scan the patients.Stone specimens were analyzed using an automatic infrared spectroscopy analysis system for stones.The detection amount of different components of stones in patients were observed,the CT value of stones,and the sensitivity,specificity,and accuracy of CT examination were detected.Result:Using infrared spectroscopy as the gold standard,a total of 24 urate stones and 99 non urate stones were detected.The CT measurement results showed that the CT values of urate stones at 140 and 80 kV were lower than those of non urate stones,and the differences were statistically significant(P<0.05);the difference and ratio of CT values for urate stones were lower than those for non urate stones,the differences were statistically significant(P<0.05).The CT examination results showed a diagnostic sensitivity of 83.33%,a specificity of 98.99%,and an accuracy of 95.93%.Conclusion:CT has high accuracy in the chemical composition analysis of urinary calculi,which can distinguish stones with different components,enabling physicians to make accurate judgments,and providing accurate reference basis for clinical diagnosis and treatment guidance.
