【摘要】 目的观察二次电切治疗非肌层浸润性膀胱癌的疗效,并进一步探讨二次电切的意义及指征。方法28例初次电切诊断为非肌层浸润性膀胱癌(Ta、T1)患者于4~6周后行二次电切,进一步明确肿瘤的临床分期。结果二次电切中发现3例(10.7%)存在肿瘤残留情况。9例初次电切分期为Ta的肿瘤中,二次电切后2例(22.2%)的病理结果为T1期,1例(3.6%)病理为T2期;而19例初次电切分期为T1的肿瘤中,二次电切结果有5例(26.3%)的病理为T2期。根据二次电切结果及镜检情况,4例行膀胱部分切除,2例行全膀胱切除+回肠代膀胱术,均得到治愈。结论二次电切可进一步明确非肌层浸润性膀胱癌的临床分期,并指导进一步治疗。更多还原

【Abstract】 Objective To observe the clinical efficiency of second transurethral resection of bladder tumor on nonmuscle invasive bladder cancer,and to investigate the significance and indications of second transurethral resection of bladder tumor for non-muscle invasive bladder cancer. Methods The 28 patients first diagnosed with non-muscle invasive bladder cancer( Ta,T1) accepted a second transurethral resection of bladder tumor 4-6 weeks later. Results In the second transurethral resection of bladder tumor,3 patients( 10. 7%) were found the residual tumors.Of the 9 patients first diagnosed with stage Ta,2 patients( 22. 2%) were in stage T1,1 patient( 3. 6%) were in stage T2; of the 19 patients first diagnosed with stage T1,5 patients( 26. 3%) were diagnosed with stage T2 in the second time. According the second pathology result,4 cases were cured through partial resection of the bladder,2 cases were cured through radical cystectomy and ileal neubladder. Conclusion Second transurethral resection of bladder tumor could give a more accurate stage of non-muscle invasive bladder cancer,and guide the next therapy.更多还原
