原发性输尿管癌的诊断策略

The diagnosis of primary ureteral cancer.

目的:探讨提高诊断原发性输尿管癌的方法。方法;回顾性分析14例原发性输尿管癌的诊断过程,术前行尿脱落细胞学检查、B超检查、IVU检查、逆行尿路造影、膀胱镜检、CT检查、MRU检查及输尿管镜检查。结果:14例术后病理回报均为原发性输尿管移行细胞癌。尿脱落细胞检查阳性率为14.3％,B超、CT及MRU检查阳性率分别为42.8％、60％和33.3％,而输尿管镜检查阳性率为100％。结论:及时联合应用多种诊断方法是提高诊断原发性输尿管癌的关键。

Objective To improve the diagnosis of primary ureteral cancer. Methods: 14 cases of primary ureteral cancer treated in the last decade were reviewed. Results:These 14 cases were postoperatively diagnosed as primary ureteral cancer. The positive rates of urine cytology, ultrasonography, CT scanning and MRU were 14.3% ,42.8% ,60% and 33.3% respectively. Conclusions:The diagnostic accuracy might be improved by combined use of many diagnostic means before surgery.
