目的 :探讨膀胱肿瘤并前列腺增生的病理特点和治疗方法。方法 :回顾性分析 5 3例膀胱肿瘤并前腺增生的临床资料。结果 :移行上皮细胞癌 46例 ,非移行上皮细胞癌 7例。随访 47例 ,时间 6月 - 12 4月 ,18例例同期手术和 2 7例未切除前列腺者复发率分别为 2 2 .2 %、2 5 .6 % ,平均复发时间分别为 31月、2 6 .4月 ,均有一例发生前列腺部尿道肿瘤。结论 :前列腺增生可引起膀胱肿瘤病理类型变化 ;只要重视术中、术后采取预防复发措施 ,同期手术不增加膀胱肿瘤复发机会 Objective: To investigate the pathological features and treatment of bladder tumor and benign prostatic hyperplasia. Methods: A retrospective analysis of 53 cases of bladder tumor and gland hyperplasia of clinical data. Results: 46 cases of transitional cell carcinoma and 7 cases of non-metastatic epithelial cell carcinoma. The follow-up was performed in 47 cases. The recurrence rate was 18.2% and 25.6% respectively in 18 cases of the same period and 27 cases of unrelated prostate in the time of June-April. The average recurrence time was 31 months and 2 respectively 6.4 months, there was a case of prostate urethral tumor. Conclusions: Prostatic hyperplasia can cause changes of pathological types of bladder tumor. As long as intraoperative and postoperative measures are taken to prevent recurrence, the same period of operation does not increase the chance of recurrent bladder tumor
