经直肠超声在急诊检查输尿管中下段结石中的应用

Value of endosonography in emergency diagnosing distal ureteral calculi

目的探讨经直肠超声在急诊检查输尿管中下段结石中的应用价值。方法选择收治的106例经超声、逆行肾盂造影、体外冲击波碎石及输尿管镜腔内气压弹道碎石术证实的输尿管结石患者为研究对象,所有患者均进行经腹部超声及经直肠超声两种检查方法并进行结果对比。结果 106例已证实输尿管结石患者经腹部超声检查确诊75例,准确率为70.8%;而经直肠超声检查确诊101例,准确率为95.3%;经直肠超声组较经腹部超声组患者检查结果准确率高且存在显著统计学差异。结论经直肠超声可以较准确的显示输尿管中下段结石,患者不需要充盈膀胱,不受婚否的限制,可显著提高诊断率。

Objective To explore the value of endosonography in emergency diagnosing distal ureteral calculi.Methods106 patients were confirmed diagnosed as urinary calculi by ultrasonograph,retrograde pyelography,etc.All of the cases were detected by transabdominal scanning and per rectum ultrasonograph,and the results were compared.Results75 patients were confirmed diagnosed by transabdominal scanning in the 106 patients（70.8%）,and 101 patients were confirmed diagnosed per rectum ultrasonograph in the 106 patients（95.3%）.Endosonograthy had higher curacy rate than transabdominal scanning in diagnosing middle and lower ureteral calculi.ConclusionUsing endosonography in diagnosing middle and lower ureteral calculi is quick convenient with high accuract rate.It is not restricted by the fullness of urocyst or the marital status.
