肾盂输尿管连接部梗阻X线诊断分析

X-ray diagnosis of pelviureteric junction obstruction

目的回顾性分析16例肾盂输尿管连接部梗阻病因、X线、CT表现,以进一步提高对病因诊断认识,提高术前诊断准确率。方法采用排泄性尿路造影,逆行尿路造影,CT检查诊断肾盂输尿管连接部阻梗16例。结果所有病例均清晰显示梗阻的连接部形态特征及尿路积水情况。结论尿路造影结合CT检查是诊断肾盂输尿管连接部梗阻病因的重要手段,对病因定性、鉴别具有重要意义,对手术治疗可提供重要信息。

Objective To improve the diagnostic accuracy of X- ray and CT in the pelviureteric junction obstruction.Methods Sixteen patients with pelviureteric junction obstruction underwent excretory urography,retrograde urography and CT examinations.X- ray and CT findings in all patients were analyzed retrospectively.Results On X- ray and CT images in all patients the morphologic features and hydronephrosis state of pelviureteric junction obstruction were clearly visualized.Conclusion Urography combined with CT examination is main means for detecting the pathogenic causes of pelviureteric junction obstruction and plays important role in the qualitative,differential diagnosis so that it can provide the useful informations for the surgery.
