原发性输尿管癌的影像学诊断

目的：评价原发性输尿管癌的各种影像学诊断方法的价值。材料与方法：本院４例及复习文献５４例经手术病理证实的原发性输尿管癌共５８例，行膀胱镜检４１例，静脉肾盂造影（ＩＶＰ）４４例，逆行肾盂造影４４例，Ｂ超４５例，经皮肾穿刺肾盂造影１２例，ＣＴ及ＭＲＩ３例。结果：膀胱镜检查表现为输尿管口肿物突出，阳性率为５８％；ＩＶＰ表现为肾积水或患肾不显影，阳性率为１００％，但无特征性；逆行肾盂造影表现为输尿管充盈缺

The Imaging Diagnosis of Primary Ureteral Carcinoma

PURPOSE:To appreciate the value of kinds of imaging methods in the diagnosis of primary ureteral carcinoma. MATERIALS AND METHODS:4 cases of our hospital and 54 cases of literature with primary ureteral carcinoma proved by pathologically and opratively were reviewed.The imaging methods included:cystocopy(n=41),intravenous pyelography(n=44),retrograde pyelography(n=44),B-ultrasonography(n=45),puncturatiopyelography(n=12),CT and MRI(n=3),RESULT:The cystocopy manifested tumor sticking out from the outlet of ureter(sensitivity was 58%).IVP and B-ultrasonography showed hydronephrosis which was not characteristic signs.Retrograde pyelography demonstrated ureteral filling defect and occlusion(sensitivity was 93%).Puncturatiopyelography had the same appearance as retrograde pyelography(sensitivity was 100%).CT and MRI findings were local thickness of ureteral wall or soft tissue mass(sensitivity was 90% and 100% respectively).CONCLUSION:Retrograde pyelography and puncturatiopyelography are the most useful method in diagnosis of primary ureteral carcinoma.B-Ultrasonography is suitable to be screening methods.CT and MRI is helpful to determine the stage of tumor.
