46例输尿管移行细胞癌的诊断与治疗

目的：探讨输尿管移行细胞癌的诊断方法和治疗效果。方法：分析46例经病理诊断的输尿管移行细胞癌的临床资料。结果：尿脱落细胞学、B超、计算机断层扫描（CT）、磁共振尿路成像（MRU）、膀胱镜及逆行肾盂、输尿管造影等检查阳性率分别为：60．0％（18／30）、21．7％（10／46）、73．7％（28／38）、100．0％（17／17）、85．0％（34／40）、88．9％（24／27）。6例原位复发，5例发生膀胱转移，9例发生远处转移，12例死亡.结论：CT、膀胱镜检查及逆行肾盂、输尿管造影和MRU是最重要的诊断手段，肾、输尿管全程切除及输尿管膀胱开口袖状切除是首选术式。

Treatment and Diagnosis of Ureteral Transitional Cell Carcinoma

Objective To probe into the dignosis and treatment of transitional cell carcinoma of ureter.Methods 46 cases of transitional cell carcinoma of ureter were analyzed retrospectively.Results The diagnostic positive rates of urine exfoliative cytology,B model ultrasound scanning(B US),computerized tomoscanning(CT),magnetic resonance urography(MRU),cystoscopy and retrograde ureteropyelography were 60.0%,21.7%,73.7%,100.0%,85.0% and 88.9% respectively.Recurrence at original place of tumor occurred in 6 and the bladder metastasis in 5 and abevacuation in 9 cases.12 cases died.Conclusion CT,MRU,cystoscopy and retrograde ureteropyelography are the most important diagnostic approaches.Radical nephroureterectomy and a cuff resection of bladder mucosa should be the treatment of choice.
