摘要
目的:从图像质量、患者感受、辐射剂量、使用效率等方面分析探讨新型输尿管压迫装置(专利号:201920650500.8)在传统静脉肾盂造影(IVP)检查中的应用价值。方法:选取81例行IVP检查的患者,根据采用的不同IVP操作方式分为新型压迫装置组(使用新型压迫装置,47例)和对照组(使用传统压迫装置,34例)。分别记录两组的检查结果、加压操作时间、图像质量等数据,并进行统计学分析。结果:对照组29例患者检查成功,5例检查失败,新型压迫装置组46例患者检查成功,1例检查失败,两组患者的检查成功率差异有统计学差异(χ^(2)=4.55,P=0.03)。新型压迫装置组在加压操作时间、主观评价、患者感受等指标上与对照组差异有统计学意义(P值均<0.01);两组的光子入射比(P=0.1)和曝光指数(P=0.43)差异无统计学意义。Pearson分析结果显示多个指标与患者感受显著相关(P<0.01),以患者感受为状态变量的ROC曲线显示加压操作时间的曲线下面积最大(0.71),质控图显示违反规则的点均在对照组。结论:IVP检查中使用新型输尿管压迫装置,明显提高了图像主观评价与患者感受,在保证检查成功率的前提下,显著降低了压迫操作时间,提高了使用效率,值得临床推广应用。
Objective:To analyze and discuss the value of the new ureteral compression device(Patent No.:2019206500.8)in traditional IVP examination from the aspects of image quality,patient perception,radiation dose and efficiency.Methods:Eighty-one patients undergoing IVP were selected and divided into two groups:new compression device group(47 cases with new compression device)and control group(34 cases with traditional compression device),according to different IVP operation methods.The examination results,pressure operation time,image quality and other data of the two groups were recorded and analyzed statistically.Results:In the control group,29 patients were successfully examined and 5 failed,while in the new compression device group,46 patients were successfully examined and 1 failed.The difference of the success rate between the two groups was statistically significant(χ^(2)=4.55,P=0.03).The difference of the pressure operation time,subjective evaluation and patient perception between the new compression device group and the control group was statistically significant(all P<0.01).There was no significant difference between the two groups in photon incidence ratio(P=0.1)and exposure index(P=0.43).Pearson analysis showed that multiple indicators were significantly correlated with patient perception(P<0.01).ROC curve with patient perception as state variable showed the maximum area under the curve of pressure operation time(0.71).The quality control chart showed that the points violating the rules were all in the control group.Conclusion:The new ureteral compression device in IVP can improve the subjective evaluation of images and the perception of patients.On the premise of ensuring the success rate of the examination,the new device can significantly reduce the pressure operation time and improve the efficiency,and thus it is worth popularizing and applying in clinic.
