摘　　要：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。Objective：To improve the knowledge of imaging manifestations of ketamine associated urinary system dysfunction. Methods： The pre-and post-contrast enhanced multi-slice CT （MSCT） as well as CT urography of 5 patients with 2-4 years history of ketamine taking were retrospectively analyzed. Results： All of the 5 patients showed bilateral kidney enlargement, bilateral hydronephrosis and dilation of renal pelvic-ureteric junction, thickening of bilateral （n=4） or unilateral （n= 1） ureteral wall, irregular thickening of bladder wall and reduction of bladder volume. Moreover, seminal vesicles swelling and blurring of vesicle triangle in 3 patients were displayed on CT without contrast administration. On enhaneed CT and CT urography, the whole course of bilateral （n= 4） or unilateral （n= 1） ureteral wall thickening and rigidity as well as no contrast agent filling in both ureters and bladder were showed in all these 5 patients. Conclusion：Typical MSCT findings could be revealed in patients with Ketamine associated urinary system dysfunction. Accurate diagnosis could be made by MSCT characteristics in combination with the understanding of clinical materials especially the history of Ketamine taking.
