目的:探讨异时发生的上尿路上皮肿瘤的临床特点。方法:回顾性分析1994~2015年收治的24例术后肿瘤复发、对侧上尿路发生移行细胞癌患者资料。结果:术后肿瘤复发、对侧上尿路发生移行细胞癌的病例包括男4例,女19例,异时肿瘤间隔1~124个月,平均49.1个月。随访1~116个月,平均42个月。18例异时性上尿路肿瘤患者死亡,5例存活。结论:尿路上皮肿瘤具有多发性和复发性的特点,应加强早期发现、早期诊断方面的研究。
Objective: To investigate the clinical features of metachronous urothelial tumors. Methods: Retrospective analysis of 24 cases of recurrent tumor recurrence in 1994 to 2015, the contralateral upper urinary tract occurred in patients with transitional cell carcinoma. Results: There were 4 males and 19 females with postoperative tumor recurrence and transitional cell carcinoma of the contralateral upper urinary tract. The mean time between neoplasms was 1 ~ 124 months with an average of 49.1 months. Follow-up 1 ~ 116 months, an average of 42 months. 18 patients with metachronous upper urinary tract cancer died and 5 survived. Conclusion: The urothelial tumors are characterized by multiple recurrent and recurrent. The study of early detection and early diagnosis should be strengthened.
