目的　应用CT解剖学的方法研究不同层面上肾前、后筋膜在肾脏外侧融合形成锥侧筋膜的解剖位置。  方法　回顾性分析66例急性胰腺炎患者的CT资料；以相邻椎体为参照，观察并记录其双侧肾前、后筋膜在不同层面上融合形成锥侧筋膜的解剖位置。  结果　（1）66例患者中，55侧显示肾前、后筋膜在左肾外侧延伸形成锥侧筋膜，64侧显示肾前、后筋膜在右肾外侧延伸形成锥侧筋膜；（2）肾前、后筋膜融合形成锥侧筋膜的解剖位置自肾门至锥下间隙水平呈相对固定的83侧；33侧呈自前向后移动；3侧呈自后向前移动；（3）肾前、后筋膜融合形成锥侧筋膜的解剖位置，双侧一致的36例，不一致的30例。  结论　肾前、后筋膜融合形成锥侧筋膜的解剖位置多位于邻近椎体前后缘之间；其解剖位置在不同层面上可不固定，且双侧可不对称。

Objective　To study the anatomic position of the lateral conal fascia on different levels formed by the anterior and posterior renal fasciae outside of the kidney.　Methods　A retrospective analysis of the CT images of 66 patients with acute pancreatitis has been done. The anatomic position of the integration of anterior and posterior renal fasciae outside of the kidney on different levels has been observed and recorded with the edge to the adjacent vertebral bodies as a reference.　Results　(1) Among 66 cases, 55 sides showed the integration of the lateral conal fascia outside the left kidney while 64 sides showed the integration on the right. (2) 83 sides showed constant anatomic position of the integration from the level of the renal helium to the infraconal space; moving from front to rear (33 sides); moving from rear to front (3 sides). (3) The anatomic location of the integration was showed cconsistent on both sides in 36 cases while inconsistent in 30 cases.　Conclusion　The integration of the anterior and posterior renal fasciae was mostly located between the prior and post edges of adjacent vertebrae; It’s not always constant on different levels, and it can be asymmetric on both sides.
