静脉肾盂造影(intravenous pyelography,简称IVP)是一种通过静脉注射含碘造影剂后,利用X射线观察泌尿系统结构的医学影像学检查方法。该技术主要用于评估肾脏、输尿管和膀胱的形态与功能,尤其适用于检测尿路梗阻、结石或先天性畸形等疾病。
核心原理与过程
检查时,造影剂经静脉注入后通过血液循环到达肾脏,随尿液排泄至肾盂、输尿管及膀胱。医生在特定时间间隔(如注射后5分钟、15分钟、30分钟)拍摄X光片,记录造影剂在泌尿系统中的动态分布,从而判断器官结构异常或排泄功能障碍。
临床应用范围
注意事项与局限性
由于需要碘造影剂,肾功能不全患者存在肾毒性风险,部分人群可能出现过敏反应。随着CT尿路造影(CTU)等新技术的普及,IVP的应用已逐渐减少,但在特定临床场景中仍具诊断价值。
权威医学资料可参考《坎贝尔泌尿外科学》及放射学专业期刊《Radiology》相关研究论文。
Intravenous pyelography(简称IVP)是医学影像学中的一种检查技术,中文译名为静脉肾盂造影术或排泄性肾盂造影术。以下为详细解释:
术语分解
用途与原理
该技术主要用于诊断泌尿系统疾病,如肾结石、肾积水、肿瘤或尿路梗阻等。通过静脉注射含碘造影剂后,造影剂经肾脏排泄至尿路,在不同时间点拍摄X光片,动态观察泌尿系统的形态和功能。
检查流程
根据2025年发布的《医学X线检查操作规程》,流程包括:
注意事项
IVP是一种结合静脉注射和X射线成像的传统诊断技术,需严格遵循操作规范以确保安全性和准确性。
