目的探讨ＣＴ对确定肾损伤范围和提供手术指征方面的价值。方法回顾分析了３２例肾创伤病人的ＣＴ表现。结果ＣＴ清楚地显示了肾创伤的三种基本类型：挫伤、裂伤、梗塞；将裂伤分为：小的表浅裂伤、大的深部裂伤有／无尿外渗、断裂伤、粉碎伤；通过增强后无血供的肾断片或梗塞灶无增强，ＣＴ可以间接诊断血管撕裂或动脉闭塞；ＣＴ能确定血肿和尿外渗的范围；检出了腹腔和腹膜后损伤及肾的原有异常。结论ＣＴ为所有肾损伤病人的处理提供了足够的资料，且所有ＣＴ发现都被手术证实。手术探查的ＣＴ指征是：大裂伤伴包膜外尿外渗、无血供肾断片、碎裂肾和血管损伤、严重合并伤
Objective To explore the value of CT in determining the scope of renal injury and providing indications for surgery. Methods The CT findings of 32 cases of renal trauma patients were retrospectively analyzed. Results CT clearly showed that the three basic types of renal trauma: contusion, laceration, infarction; the laceration is divided into: small superficial laceration, large deep laceration with / without urine extravasation, laceration, crushing Injuries; CT enhancement can be used to diagnose vascular rupture or arterial occlusion indirectly through enhancement of nondeficient renal fragments or infarct enhancement; CT can determine the extent of hematoma and extravasation; detection of peritoneal and retroperitoneal injuries and renal The original exception. Conclusion CT provided sufficient information for the treatment of all patients with renal injury, and all CT findings were surgically confirmed. Surgical exploration CT indications are: large laceration with extracapsular urinary extravasation, no blood supply to the kidneys, broken kidneys and vascular injury, severe combined injury
