We report a case of bladder cancer recurrence in fossa navicularis of urethra 17 months after cystourethrectomy for bladder cancer. A 75-year-old man had undergone cystourethrectomy preserving between fossa navicularis and external meatus, and ileal conduit urinary diversion for advanced bladder cancer on June 24, 2002. Histopathological findings showed urothelial carcinoma, G2>G3, pT1N0. The patient had been followed regularly for 17 months without evidence of recurrence until he suffered the onset of hemorrhagic urethral discharge. Endoscopic examination of the residual urethra showed multiple, papillary sessile tumors which almost filled the fossa navicularis. He was admitted to our hospital on December 15, 2003. The urethral wash cytology revealed urothelial carcinoma. Since computed tomography, magnetic resonance imaging, and bone scintigraphy showed no evidence of lymph node and distant metastasis, partial penectomy was performed. Histopathological findings showed urothelial carcinoma pTa, G2>G3, which was identical to primary tumor. Tumor had not invaded the corpus cavernosum. Careful follow-up of the patients with preservation of fossa navicularis is important.
我们报告一例膀胱癌患者在膀胱尿道切除术后17个月，尿道舟状窝出现膀胱癌复发。一名75岁男性于2002年6月24日因晚期膀胱癌接受了保留尿道舟状窝和尿道口之间部分的膀胱尿道切除术及回肠代膀胱术。组织病理学检查结果显示为尿路上皮癌，G2>G3，pT1N0。患者定期随访17个月，无复发迹象，直到出现尿道出血性分泌物。对残留尿道进行内镜检查发现多个乳头状无蒂肿瘤，几乎充满尿道舟状窝。他于2003年12月15日入住我院。尿道冲洗细胞学检查显示为尿路上皮癌。由于计算机断层扫描、磁共振成像和骨闪烁显像均未发现淋巴结及远处转移迹象，遂行部分阴茎切除术。组织病理学检查结果显示为pTa期尿路上皮癌，G2>G3，与原发肿瘤相同。肿瘤未侵犯海绵体。对保留尿道舟状窝的患者进行仔细随访很重要。
