摘　　要：目的 探讨肾周间隙桥隔正常走向及异常增厚的CT表现.方法 回顾性分析75例肾周间隙桥隔增厚的CT表现.结果 肾周间隙桥隔增厚的原因可为肾源性、非肾源性疾病或原因不明.肾源性疾病包括肾外伤26例,肾结核2例,肾脓肿4例,肾盂肾炎3例,尿路梗阻15例,肾癌2例.非肾源性疾病包括急性胰腺炎15例,急性胆囊炎1例,腹膜炎2例,结肠癌3例.原因不明者2例.肾周间隙桥隔增厚的CT表现为肾周间隙内的条状、分支状软组织影.结论 肾周间隙桥隔增厚的病因多样化,影像学检查对探其病因有一定作用.Objective To evaluate anatomic traveling direction and CT findings of thickening of the bridge septa of perinephric space.Methods 75 cases of diseased samples were examined by CT, and CT signs of the thickened bridge septa of perirenal space were analyzed retrospectively.Results Thickening of the bridge septa of perinephric space was observed in three specific etiological groups：group one for renal diseases,in which there were renal trauma （26 cases）,renal tuberculosis （2 cases）,renal abscess （4 cases）,pyelonephritis （3 cases）, urinary tract obstruction （15 cases） and renal cancer （2 cases）;group two for non-renal diseases, in which there were acute pancreatitis （15 cases）, acute cholecystitis （1 case）,peritonitis （2 cases） and colon cancer （3 cases）;group three for unknown origin （2 cases）.The images findings appeared as multiple stripes or branching shadows locating in the perinephric space.Conclusion The etiological factor of the bridge septa thickening is varied.CT can show the thickened bridge septa of perirenal space accurately,and identify the etiological factors.
