目的：提高原发性输尿管癌的诊治。方法：分析３３ 例病例通过超声、静脉尿路造影（ＩＶＵ） 、膀胱镜和逆行造影进行诊断， 部分病人接受ＣＴ 和磁共振水成像检查。结果： 所有病例均行手术，２１ 例获得术前确诊。结论：ＩＶＵ、膀胱镜和逆行造影仍是基本检查手段，对于部分病例，ＣＴ 和磁共振水成像（ ＭＲＵ） 有重要诊断价值。肾输尿管全长及膀胱部分切除术仍是主要术式。
Objective: To improve the diagnosis and treatment of primary ureteral cancer. Methods: Totally 33 cases were diagnosed by ultrasonography, intravenous urography (IVU), cystoscopy and retrograde angiography. Some patients underwent CT and magnetic resonance imaging. Results: All the cases were operated on and 21 cases were diagnosed preoperatively. Conclusions: IVU, cystoscopy and retrograde angiography are still the basic examination methods. CT and MRU have some important diagnostic value in some cases. Total length of the renal ureter and partial resection of the bladder is still the main technique.
