Abstract: Objective To investigate the diagnostic value of color Doppler ultrasound in ureteral calculi in different parts in emergency. Methods A total of 246 cases of ureteral calculi in emergency admitted to Chashan Hospital of Dongguan between January 2019 and December 2020 were selected as the research objects, including 142 males and 104 females, aged (46.62±3.77) years. They all received routine ultrasound examination and color Doppler ultrasound examination. The calculus detection rates of different parts of the ureter of the two methods were compared. The count data were compared by χ2 test. Results The detection rates of calculi and hydronephrosis by color Doppler ultrasound were 98.47% (258/262) and 98.70% (152/154), respectively, which were significantly higher than those by conventional ultrasound [90.08% (236/262) and 93.51% (144/154)], with statistically significant differences (both P<0.05). The detection rates of upper ureteral calculi by conventional ultrasound and color Doppler ultrasound were both 100.00% (101/101), with no statistically significant difference (P>0.05). The detection rates of middle and lower ureteral calculi, left and right ureteral calculi by color Doppler ultrasound were 98.77% (80/81), 96.25% (77/80), 98.41% (124/126), and 98.53% (134/136), respectively, which were significantly higher than those by conventional ultrasound [80.25% (65/81), 87.50% (70/80), 91.27% (115/126), and 88.97% (121/136)], with statistically significant differences (all P<0.05). Conclusion Strengthening the application of color Doppler ultrasound in the diagnosis of ureteral calculi in emergency can achieve accurate detection of calculi in different parts, especially for the diagnosis of middle and lower ureteral calculi, and is not affected by the left and right sides of the ureter, worthy of promotion.

摘要： 目的 探讨彩色多普勒超声对不同部位急诊输尿管结石的诊断价值。方法 回顾性选 取2019年1月至2020年12月期间东莞市茶山医院收治的急诊输尿管结石患者246例作为研究对象， 其中男 142例、女 104例，年龄（46.62±3.77）岁，均接受常规超声检查及彩色多普勒超声检查，并比较两种方法对输尿管不同部位的结石检出率。计数资料行χ2 检验。结果 彩色多普勒超声对结石、肾 盂积水检出率分别为 98.47%（258/262）、98.70%（152/154），均显著高于常规超声 90.08%（236/262）、 93.51%（144/154），差异均有统计学意义（均P<0.05）。常规超声和彩色多普勒超声检出输尿管上段结石率均为100.00%（101/101），差异无统计学意义（P>0.05）；彩色多普勒超声对输尿管中段、下段及输尿管左侧、右侧结石检出率分别为98.77%（80/81）、96.25%（77/80）、98.41%（124/126）、98.53%（134/136）， 均显著高于常规超声 80.25%（65/81）、87.50%（70/80）、91.27%（115/126）、88.97%（121/136），差异均有统计学意义（均P<0.05）。结论 急诊输尿管结石诊断中加强对彩色多普勒超声的应用可实现不同部位结石的准确检出，尤其对中下段结石诊断价值高，且不受输尿管左侧与右侧位置影响，值得推广。
