氯胺酮相关性泌尿系统损害MSCT表现及文献复习

目的：探讨滥用氯胺酮所致泌尿系统损害的MSCT表现。方法：回顾性分析5例有吸食氯胺酮病史（2～4年）患者的泌尿系统MSCT平扫、增强扫描及CT尿路成像资料，分析其影像学特征。结果：5例患者CT平扫示双肾体积增大，双肾积水并肾盂输尿管移行段扩张，双侧（4例）或单侧（1例）输尿管壁增厚，膀胱壁不规则增厚、容积减小，3例精囊腺肿胀，膀胱精囊三角显示不清；增强扫描示双侧（4例）或单侧（1例）输尿管管壁全程均匀性增厚强化、管壁僵硬，双侧输尿管和膀胱未见对比剂充盈。结论：吸食氯胺酮所致泌尿系统损害具有典型的影像学表现，MSCT能揭示病变的特征，结合临床资料及病史可正确诊断。
