超声定位碎石在输尿管中段结石治疗中的应用

目的探讨超声对输尿管中段结石诊断及超声引导下进行体外冲击波碎石的应用价值。方法对324例超声诊断输尿管中段结石患者进行体外冲击波碎石治疗,并分析输尿管中段结石的超声诊断技巧、定位准确性及碎石效果,追踪观察碎石后并发症的发生。结果本组患者均顺利完成输尿管结石超声显像及碎石治疗,98.5%获得较满意疗效。结论超声诊断及定位体外冲击波碎石治疗输尿管中段结石是目前非手术治疗的首选方法 ,可替代绝大部份X光定位碎石及输尿管镜取石。

Application of localized ultrasound lithotripsy in the treatment of middle-ureteral calculi

Objective To explore the value of ultrasonography in the diagnosis of middle-ureteral calculi and the application of ultrasound-guided extracorporeal shock wave lithotripsy (ESWL). Methods Three hundred and twenty-four patients of middle-ureteral calculi were treated by ultrasound-guided ESWL. The positioning accuracy and calculus breaking effect were analyzed, and the incidence of complications after calculus breaking was observed. Results The ultrasound diagnosis and ESWL were successfully performed in all the patients, with a success rate of 98.5% (319/324). Conclusion Ultrasound diagnosis and ultrasound localized ESWL is currently a preferred method for treating middle-ureteral calculi, which can be used to substitute most of the X-ray positioning lithotripsy and ureteroscopy calculus removing.
