Abstract: 目的 探讨多层螺旋CT在IVU未充分显影的上尿路梗阻性疾病诊断中的应用价值.方法 应用多层螺旋CT对52例经超声检查提示但IVU检查未能充分显影且血肌酐正常的上尿路梗阻性病变患者行平扫加增强检查.结果 52例多层螺旋CT诊断为肾盂输尿管连接部梗阻16例、肾结核8例、输尿管结石10例、输尿管良性狭窄6例、输尿管癌4例、输尿管外压迫6例、巨输尿管2例.10例结石性上尿路梗阻中,输尿管镜证实8例,开放手术证实2例.42例非结石性上尿路梗阻中,2例诊断为腹膜后淋巴结转移癌压迫输尿管者,仅行输尿管内双J管植入术,未获得病理证实;2例诊断为前列腺癌侵及输尿管末段者,由前列腺穿刺活检证实;其余38例均行开放手术经病理证实.52例中有50例得到手术病理证实.结论 对IVU未能充分显影且血肌酐正常的上尿路梗阻患者,多层螺旋CT平扫加增强在判断梗阻原因方面有重要价值.
