摘　　要：目的:探讨输尿管末端结石实施二维超声诊断的意义及影响超声诊断结果的相关因素。方法:对本院2017年1月至2018年8月120例疑似输尿管末端结石患者实施观察研究,对所有患者均进行二维超声检查和螺旋CT检查,以螺旋CT检查结果为诊断标准,分析总结二维超声的图像特征、诊断效果,并对所有患者的资料进行分析,总结二维超声诊断输尿管末端结石时误诊漏诊的影响因素。结果:实施二维超声检查时漏诊9例,误诊2例,二维超声检查对输尿管末端结石的诊断敏感性为91.3%(95/104),特异性为87.5%(14/16),准确性为90.8%(109/120)。不同性别、不同年龄患者二维超声检查对输尿管末端结石的诊断效果对比对比无明显差异(P>0.05)。肥胖患者二维超声检查对输尿管末端结石的诊断误诊或漏诊发生率显著高于非肥胖患者(P<0.05)。膀胱容量<110mL患者二维超声检查对输尿管末端结石的诊断误诊或漏诊发生率显著高于膀胱容量≥110mL患者(P<0.05)。结论:输尿管末端结石实施二维超声诊断效果良好,漏诊和误诊状况较少,且肥胖、膀胱容量是影响诊断效果的影响因素,需针对上述因素进行针对性处理,以提升诊断效果。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.
