Abstract

　　Objective：To evaluate the value of enhanced and delayed spiral CT scans in the diagnosis of renal trauma.

　　Materials and Methods：Image data of plain spiral CT，enhanced CT，and delayed enhanced CT scans in 50 cases of renal injuries were retrospectively analyzed.

　　Results：Marginal irregularity of the kidney was displayed on plain spiral CT in 33 cases，subcapsular hematoma in 14 cases，and perinephric hemorrhage in 13 cases，renal contusion in 16 cases，renal avulsion in 7 cases. Enhanced and delayed CT scan not only showed what have been presented in the plain CT scans but also demonstrated 7 cases with external fistula of urine due to injury of collecting systems.

　　Conclusion：Enhanced and delayed CT scan are of important value in the diagnosis of renal trauma，especially in those with injuries in collecting systems.

　　Key words：Kidney Injuries Tomography， X2ray computed 　Contrast media

　　肾脏损伤常常是腹部闭合性损伤所致，螺旋CT增强扫描，尤其是延时扫描，对其诊断有重要意义。笔者搜集2002年1月～2004年4月50例因各种原因所致的肾损伤进行的螺旋CT平扫、增强及延时扫描的病例资料进行回顾性分析，探讨增强及延时扫描在肾损伤中的价值。

　　50例中，男43例，女7例，年龄7～74岁，平均35岁。其中车祸伤35例，打击伤5例，撞击伤6例，高空坠落伤4例。就诊时间30min～2个月。主要临床表现为腰、腹疼及肉眼血尿，有的合并多发伤，其中2例24h内因其他脏器严重损伤而死亡。
