目的:探讨闭合性肾损伤的诊断和治疗。方法:回顾分析2010年1月~2014年6月我院收治55例闭合性肾损伤患者的临床资料,入院时急诊CT检查,根据患者病情进一步行CTU、CTA检查,根据检查结果选择合适的治疗方案。结果:55例患者均诊断明确,非手术治疗48例,手术治疗7例。保肾治疗成功52例,失肾3例。所有患者均痊愈出院。随访3~6个月,患者恢复良好,均无明显并发症。结论:在多层螺旋CT和血管介入治疗的帮助下,能显著提高保肾率,降低不必要的手术探查。 Objective: To investigate the diagnosis and treatment of closed renal injury. Methods: The clinical data of 55 patients with closed kidney injury admitted to our hospital from January 2010 to June 2014 were retrospectively analyzed. Emergency CT examination was performed on admission. CTU and CTA were further performed according to the patient’s condition, and the appropriate treatment was selected according to the examination results Program.

Kidney treatment of 52 cases of successful treatment, loss of kidney in 3 cases. All patients were cured and discharged. Follow-up 3 to 6 months, patients recovered well, no significant complications. CONCLUSIONS: With the help of multi-slice spiral CT and vascular intervention, the rate of retention of kidneys can be remarkably improved and unnecessary surgical exploration can be reduced.
