摘　　要：目的探讨多层螺旋CT在诊断异位血管压迫所致肾盂输尿管连接部(UPJ)梗阻的应用价值。方法随机选择121例UPJ梗阻的病人行16层螺旋CT增强扫描。在AW 4.1工作站采用层厚1.25 mm作三维重建(容积再现,VR和最大密度投影,MIP)。结果121例UPJ梗阻的病人中,肾动脉解剖变异58例(47.9%),肾静脉解剖变异18例(14.9%)。变异血管压迫所致UPJ梗阻15例(12.4%)。结论多层螺旋CT对诊断异位血管压迫所致UPJ梗阻具有重要的临床应用价值。Objective： To evaluate 16 -detector Row CT in assessment of crossing vessels in kidneys with ureteropelvic junction （UPJ） obstruction. Methods： 121 consecutive patients with UPJ obstruction underwent enhanced 16 -detector Row CT. The images were reconstructed with sections of 1.25 -mm thickness reconstructed. Results ： 16 - detector Row CT depicted 58 （47.9%） with 5multiple renal arteries and 18 （ 14.9% ） with multiple renal veins in the 121 patients. Fifteen （29%） of the 121 patients with UPJ obstruction had identifiable vessels crossing the UPJ. According on surgery, CT angiography was 100% sensitive and 93.3% specific for depicting these crossing vessels. Conclusion： 16 - detector Row CT plays a much important role in the assessment of crossing vessels in kidneys with UPJ obstruction.
