降结肠与左肾位置关系的CT解剖学研究

CT anatomic study of position correlation between descending colon and left kidney

目的运用多层螺旋CT探讨降结肠相对左侧肾脏的位置分区与同侧肾筋膜外侧附着类型的相关性。方法收集121例行上腹部CT扫描的成人病例的影像学资料并进行回顾性分析,着重观察和记录降结肠相对左侧肾脏的位置分区以及同侧肾筋膜外侧附着类型,并分析二者之间的相关性。结果（1）72例的左侧肾筋膜外侧附着类型属于I型,49例的左侧肾筋膜外侧附着类型为II型;（2）降结肠整体走行呈现自左肾前方至左肾侧后方的趋势;（3）左侧肾门水平,降结肠相对左肾的位置分区与左侧肾筋膜外侧附着类型具有相关性（χ^2=6.254,P〈0.05）。结论降结肠相对左侧肾脏的位置分区与同侧肾筋膜外侧附着类型存在相关性。

Objective To discuss the correlation between subarea of the descending colon relative to the left kidney（Sa DCK） and the type of anatomic position of the left lateral conal fascia formed by the anterior and posterior renal fasciae outside of the left kidney（APLCF） using multi-slice spiral computed tomography. Methods The abdominal CT imaging data of 121 patients were collected and analyzed retrospectively. The Sa DCK and the type of the APLCF were studied, and the corresponding value was recorded. Results（1） 72 patients showed that the type of the left APLCF belonged to type I, and 49 patients showed that the type of the left APLCF belonged to type II;（2） The anatomic position of descending colon showed a trend from the front to the posterolateral side of the left kidney;（3） There was a correlation between the Sa DCK and the left APLCF at the level of the renal hilum（χ^2=6.254, P〈0.05）. Conclusion There was a correlation between the Sa DCK and the type of left APLCF.
