Abstract:
Objective:To analyze clinical application effect of color Doppler flow imaging(CDFI)combined with multi-slice spiral computed tomography(MSCT)examination under real-time ultrasound monitoring for upper urinary tract calculi.Methods:A total of 90 patients with suspected upper urinary tract calculi admitted to the 3201th Hospital were selected between June 2022 and January 2025.According to different examination methods,they were divided into MSCT group(45 cases)and combination group(45 cases,CDFI combined with MSCT examination under real-time ultrasound monitoring).Taking pathological diagnosis as the golden standard,diagnostic efficiencies of the two examination methods on upper urinary tract calculi were compared by Kappa consistency test.The coincidence rates of the two examination methods for upper urinary tract calculi and its size at different sites were observed.Results:The results of pathological diagnosis showed that 38 cases were confirmed in 45 patients of MSCT group,including 11 cases with kidney calculi and 27 cases with ureteral calculi.In them,20 cases'stone diameters were<5mm,and 18 cases'stone diameters were≥5mm.In 45 patients of combination group,40 cases were confirmed,including 16 cases with kidney calculi and 24 cases with ureteral calculi.In them,19 cases'stone diameters were<5mm and 21 cases'stone diameters were≥5mm.In MSCT group,32 cases were true positivity,2 cases were false positivity,5 cases were true negativity and 6 cases were false negativity.In combination group,39 cases were true positivity,1 case was false positivity,4 cases were true negativity and 1 case was false negativity.Compared with the golden standard,Kappa values of MSCT and combined examination were respectively 0.451 and 0.775 in diagnosing upper urinary tract calculi,and the sensitivity and accuracy of combined detection were respectively 97.50%and 95.56%,which were higher than those(84.21%and 82.22%)of MSCT examination,and the differences were significant(x2=4.213,4.050,P<0.05).There was no significant difference in detective coincidence rates of two groups of examination methods for kidney calculi and ureteral calculi(P>0.05),but detection coincidence rate of combination group for patients'calculi diameters<5mm was significantly higher than that of MSCT group,and the difference was significant(x2=4.048,P<0.05).Conclusion:CDFI combined with MSCT under real-time ultrasound monitoring has high diagnostic efficiency for upper urinary tract calculi,and its detection effect is better in detecting microcalculi with diameter of<5mm,especially.
