Value of color Doppler ultrasound in the diagnosis of ureteral calculi in different parts in emergency

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 inemergency admitted to Chashan Hospital of Dongguan between January 2019 and December 2020were 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. Thecalculus detection rates of different parts of the ureter of the two methods were compared. Thecount data were compared by χ2 test. Results The detection rates of calculi and hydronephrosisby color Doppler ultrasound were 98.47% (258/262) and 98.70% (152/154), respectively, whichwere 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 upperureteral 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 andlower 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 weresignificantly 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 ureteralcalculi in emergency can achieve accurate detection of calculi in different parts, especially for thediagnosis of middle and lower ureteral calculi, and is not affected by the left and right sides of theureter, worthy of promotion.
