TUR术治疗原位新膀胱术后再发尿道癌

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.

Transurethral resection for urethral recurrence after neobladder reconstruction in patients with bladder cancer

Objective 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.
