摘要目的 探讨膀胱癌全膀胱切除原位新膀胱术后再发尿道癌的治疗方法.方法 膀胱癌行全膀胱切除原位新膀胱术患者89例,术后发生尿道癌5例(5.6%),再发尿道癌平均时间18(9～32)个月.5例患者病理分期为T1～T2.因复发性膀胱癌行全膀胱切除术4例,因膀胱多发癌行全膀胱切除术1例.采用乙状结肠原位新膀胱术3例,回肠原位新膀胱术2例.5例患者术后因排尿不畅(3例)、肉眼血尿(1例)、血性分泌物(1例)再次就诊.尿道镜检查发现尿道肿物位于前列腺部尿道2例、阴茎部尿道3例.肿物呈菜花状向尿道腔内生长,可见基底部,肿物直径1～3 cm.尿道镜活检报告均为尿道尿路上皮癌,病理分期为T1～T2.5例均行TUR术,术后病理报告为尿道非浸润性尿路上皮癌Ⅰ～Ⅱ级.术后辅以羟基喜树碱尿道灌注,每周1次,共6周.结果 5例TUR术后平均随访37(24～52)个月,控尿满意,血尿和血性分泌物均消失,尿细胞学检查均为阴性,尿道镜检查无阳性发现.肿瘤未见复发、转移.结论 膀胱癌膀胱全切术后再发尿道尿路上皮癌可以选择保全尿道的TUR术和尿道灌注治疗,疗效较满意且生活质量良好.

abstractsObjective To explore the surgical treatment of urethral recurrence after neobladder reconstruction in patients with bladder cancer. Methods In 89 consecutive patients with radical cystectomy, 5 patients (5.6%) presented with a noninvasive urethral recurrence at a median of 18 months (range 9 to 32 months). All 5 patients were treated by transurethral resection and intraurethral instillation with hydroxycamptothecin used as initial therapy. Mean follow-up was 37 months (24 - 52 months). Results All the 5 patients survived after the treatment. There was no one showed recurrence or distant metastasis. All the 5 cases achieved continence. Conclusion Urethral preservation at initial therapy for incipient noninvasive urethral recurrence would be a good choice and could maintain the quality of life.
