摘　　要：目的：探讨多层螺旋 CT 尿路成像（MSCTU）在膀胱段输尿管病变中的诊断价值。方法回顾性分析41例膀胱段输尿管病变患者的 MSCTU 图像，所有病例均行泌尿系 CT 平扫、动脉期、实质期、排泄期扫描，将原始资料传至工作站中进行后处理，获得 MIP、VR、MPR、CRP 图像。结果（1）先天性畸形7例，其中输尿管开口异常1例，先天性巨输尿管1例，双输尿管4例，输尿管囊肿2例；（2）结石25例，其中11例伴有膀胱充盈缺损；（3）肿瘤9例，其中息肉1例，尿路上皮癌6例，前列腺癌2例。41例患者MSCTU 三维重建均能清晰显示膀胱段输尿管病变的位置、形态、大小及与周围组织的关系。结论 MSCTU 对膀胱段输尿管病变诊断准确率为97.5%（40/41），诊断价值及优势明显。Objective To explore the value of MSCTU in ureterovesical junction diseases.Methods MSCTU data in 41 patients with different diseases in ureterovesical junction were retrospectively analyzed.All patients underwent plain and triphase contrast en-hanced CT scans.The primary imaging data were transmitted to a worksation to get the maximum intensity projection （MIP）,vol-ume rendering （VR）,multiplanar reconstruction （MPR）and curve plannar reconstruction （CPR）images.Results （1）CT showed congenital abnormality in 7 patients including ectopic ureteral orifice in 1,megaloureter in 1,duplication of the urter in 4 and uret-erocele in 2.（2）Urinary stone in 25 with bladder filling defect in 1 1.（3）Tumor in 9 including polyp in 1,urothelial carcinoma in 6 and prostate cancer in 2.MSCTU clearly showed the location,shape,size of the ureterovesical junction diseases and the relationship with surrounding structures.Conclusion MSCTU plays an important role in diagnosis of ureterovesical junction diseases with an ac-curate rate of 97.5%（40/41）.
