Abstract：Objective: To explore the significance of two-dimensional ultrasonic diagnosis of ureteral end-stone and the related factors influencing the ultrasonic diagnosis results. Methods: 120 patients with suspected distal ureteral calculi in our hospital from January 2017 to August 2018 were observed and studied. Two-dimensional ultrasound examination and spiral CT examination were performed on all patients. Then, the results of spiral CT examination were taken as the diagnostic criteria to analyze and summarize the image characteristics and diagnostic effects of two-dimensional ultrasound, and the data of all patients were analyzed. To summarize the influencing factors of misdiagnosis and missed diagnosis in the diagnosis of distal ureteral calculi by two-dimensional ultrasound. Results: The results of two-dimensional ultrasound examination were 9 cases of missed diagnosis and 2 cases of misdiagnosis.The sensitivity, specificity and accuracy of two-dimensional ultrasound in the diagnosis of distal ureteral calculi were 91.3% (95/104), 87.5% (14/16) and 90.8% (109/120). Two-dimensional ultrasound examination was used in patients of different genders and ages, and the results showed no significant difference in the effect of diagnosis of distal ureteral calculi (P>0.05). The incidence of misdiagnosis or missed diagnosis of distal ureteral calculi in obese patients was significantly higher than that in non-obese patients (P<0.05). The incidence of misdiagnosis or missed diagnosis of distal ureteral calculi in patients with bladder volume < 110 mL was significantly higher than that in patients with bladder volume > 110 mL (P<0.05). Conclusion: Two-dimensional ultrasonography is effective in the diagnosis of distal ureteral calculi, and the incidence of missed diagnosis or misdiagnosis is low.Obesity and bladder volume are the direct factors that influence the diagnosis effect, which needs targeted treatment to improve the diagnosis effect.
