Abstract：【Objective】 To explore the imaging features of urinary system calculi by color Doppler ultrasound and analyze its clinical diagnostic value. 【Methods】 A retrospective analysis was conducted on the clinical data of 80 patients with urinary system calculi admitted to two hospitals from September 2021 to September 2025. All patients underwent preoperative two-dimensional ultrasound and color Doppler ultrasound examination. With surgical exploration or stone discharge after extracorporeal lithotripsy as the gold standard, the stone detection rate and segmental ureteral stone detection results of the two examination methods were compared, and the imaging characteristics of urinary calculi were summarized. 【Results】 Among the enrolled patients, 12 cases were diagnosed with bladder calculi, 31 cases with renal calculi, and 37 cases with ureteral calculi. The detection rates of bladder calculi, renal calculi and ureteral calculi by color Doppler ultrasound were significantly higher than those of two-dimensional ultrasound (all P<0.05). For upper and middle ureteral calculi, color Doppler ultrasound presented superior detection efficiency with statistically significant differences (all P<0.05). There was no significant difference in the detection rate of lower ureteral calculi between two-dimensional ultrasound and color Doppler ultrasound (P>0.05). 【Conclusion】 Color Doppler ultrasound can clearly display the ultrasonic imaging characteristics of different types of urinary system calculi. It has a significantly higher detection rate for bladder calculi, renal calculi, and upper and middle ureteral calculi than two-dimensional ultrasound, possessing important clinical application value.
