240例输尿管结石的彩超诊断分析（附240例报告）

Diagnosis and Analysis of Ureteral Stones by Color Doppler Ultrasonography （ Report of 240 cases）

目的评价彩超在输尿管结石中的诊断价值。方法回顾性分析我院从2008年1月至2010年12月临床确诊的240例输尿管结石患者彩超检查资料，其中男158例，女82例，平均年龄42岁。结果222例患者彩超确诊，诊断符合率为92．5％。其中输尿管上段结石92例，漏诊4例；中段结石47例，漏诊6例；下段结石65例，漏诊8例。同侧输尿管内，二段以上均有结石8例，双侧输尿管均有结石6例，J管旁结石5例（均位于上段）；结石大小4mm-25mm，平均大小8mm。结论彩超可清晰显示输尿管结石，具有经济、有效、方便等优点，为临床上的诊断和治疗提出更加明确可靠的依据，但对于特殊类型的输尿管结石需引起重视。

Objective To investigate the value of color Doppler in the diagnosis of ureteral stones. Method 240 cases of ureteral stones confirmed by the clinical evidence were examined by color Doppler from Jan. 2008 to Dec.2010, and the data were analyzed retrospectively. There were 158 male patients and 82 females with an average age of 42. Results 222 cases were diagnosed with an accurate rate of 92.5%. There were 92 upper ureteral stones, and missed diagnosis were 4 eases; 47 middle and 6 missed; 65 lower and 8 missed. There were 8 eases with ureteral stones located ipsilaterally on two segments or more; bilateral stones were 6 eases; and 5 cases were near the J catheter. The diameter of the stones was 4-25 mm with a mean of 8mm. Conclusions Color Doppler can display clearly the ureteral stones with the characteristics of economy, effectiveness and convenience, and can provide more accurate information for the clinical diagnosis and treatment. However, some special types need more attentions.
