Abstract:
Objective To explore the diagnostic efficacy of digital tomosynthesis(DTS)and kidney-ureter-bladder(KUB)X-ray plain filmin for urinary calculi.Methods A total of 140 patients with urinary calculi were randomly divided into observation group and control group,with 70 cases in each.The observation group underwent bowel preparation(BP)before DTS,while the control group did not.KUB,DTS and unenhanced multidetector computed tomography(UMDCT)were performed in both groups,and the three images were assessed and compared by three physicians.Results The X-ray plain filmin detection rate of stones≤5 mm in the observation group was significantly higher than that in the control group(85.46%vs 33.33%,χ2=30.75,P<0.01),and the detec-tion rate of stones>5 mm in the observation group was also significantly higher than that in the control group(100%vs 58.44%,χ2=43.12,P<0.01).The DTS detection rate of stones≤5 mm in the observation group was significantly higher than that in the control group(90.91%vs 55.56%,χ2=17.44,P<0.01),but there was no significant difference in the detection rate of stones>5 mm between the two groups(100%vs 96.10%,P>0.05).The effective dose(ED)differed significantly among X-ray plain filmin,DTS and UMDCT(P<0.001).Except for DTS,there were significant differences in imaging sensitivity between the two groups(P<0.05).Conclusion DTS is an appropriate examination method for patients with urinary calculi,which can improve the diag-nostic rate of urinary calculi and reduce the radiation dose for patients.The detection rate of stones≤5 mm in DTS is affected by BP,but the detection rate of stones>5 mm is unaffected by BP.The diagnostic sensitivity of DTS is unaffected by BP.
