目的 探讨宝石能谱CT对肾脏损 伤诊疗的临床意义。方法 以我院2012年 2月-2014年5月收治的38例肾脏损伤患者 为研究对象，均行宝石能谱CT检查，分析 肾脏损伤CT分类，并根据分类结果对症治 疗，宝石CT复查。结果 宝石能谱CT诊断 肾损伤分类：I类肾损伤14例，II类肾损 伤10例，III类肾损伤6例，体外冲击波碎 石术后造成肾周血肿4例，经皮肾镜碎石 术后穿刺通道出血4例。不同分类肾损伤 患者行对症治疗，均痊愈出院。结论 宝 石能谱CT对肾脏出血或渗尿能准确显示， 可明确判断不同类型肾损伤，为其临床治 疗提供重要影像学资料，以提高痊愈率， 减少相关并发症发生。

Objective To investigate the clinical significance of gemstone spectral CT in the diagnosis and treatment of renal injury. Methods 38 patients with renal injury treated in our hospital from February 2012 to May 2014 were taken as the research objects. All of them underwent gemstone spectral CT examination. CT classification of renal injury was analyzed and according to the classification results, the symptomatic treatment was given and gemstone spectral CT reexamination was performed. Results Classification of gemstone spectral CT in diagnosis of renal injury: type I renal injury was diagnosed by CT in 14 cases, type II in 10 cases and type III in 6 cases. 4 cases of perirenal hematoma were caused by extracorporeal shock wave lithotripsy and 4 cases of tunnel hemorrhage caused after percutaneous nephrolithotripsy. Symptomatic treatment was given to different classification of patients with renal injury. All were cured and discharged. Conclusion Gemstone spectral CT can accurately display renal bleeding or urine leakage and clearly judge different types of renal injury, which provides important imaging data for clinical treatment to improve the recovery rate and reduce the related complications.
