摘　　要：目的:探讨多层螺旋CT增强扫描在重度肾损伤中的诊断价值。方法:回顾性分析26例重度肾损伤患者的CT平扫及增强扫描特点,15例与手术结果相对照,11例临床随访观察,明确CT多期增强扫描在重度肾损伤中的诊断价值。结果:26例患者均为重度肾损伤,11例肾实质裂伤深度超过1.0 cm,无集合系统破裂或尿外渗;10例肾损伤贯穿肾实质和集合系统,肾动脉、静脉主要分支损伤,形成明显肾周血肿和尿外渗;粉碎肾5例。结论:多层螺旋CT多期增强扫描能明确重度肾损伤的程度及范围,对指导临床采取及时的手术治疗有较大的指导意义。Objective: To explore the value of contrast enhanced multiphase spiral CT in diagnosing severe renal trauma.Methods: The imaging characters of plain CT scan and contrast-enhancement scan in 26 patients were reviewed.Fifteen cases of them were compared with the operation results and 11 cases were observed clinically.Results: Twenty-six cases were all severe renal trauma,the depth of laceration in 11 cases was over 1.0 cm without the rupture of collection system or urinary extravasation,in 10 cases,the laceration involved the whole renal parenchyma,collection system and the main branches of renal arteries and veins,which caused perirenal hematoma and urinary extravasation obviously.Crushed kidneys were diagnosed in 5 cases.Conclusion: The multiphase spiral CT can define the degree and range of the severe renal trauma,and can provide reliable evidence for clinical operation treatment.
