探讨脐尿管癌的诊断和治疗策略。

2019年11月我院收治脐尿管癌患者1例，女性，69岁，完善相关准备后行腹腔镜下扩大性膀胱部分切除及脐尿管和脐切除术。结合国内外文献报道，讨论脐尿管癌的发病特点、诊断要点及治疗策略。

术前CT检查示膀胱顶部新生物形成，局部隆起样改变，膀胱镜检查示膀胱顶部肿瘤，活检病理结果提示腺癌。手术顺利，手术时间约3 h，术中出血约20 ml，术后病理结果示中分化腺癌、切缘阴性，术后患者恢复良好。

脐尿管癌的诊断依靠临床表现、影像学、膀胱镜检查及免疫组织化学染色，治疗上采用脐、脐尿管及膀胱部分切除术并联合术后化疗。

The aim of this study was to explore the diagnosis and treatment strategy of urachal carcinoma.

In November 2019, one case of urachal carcinoma patient was admitted to our hospital, female, 69 years old. After completing the relevant preparations, laparoscopic partial cystectomy and urachal and umbilical resection was performed. Combined with the domestic and foreign literature reports, this paper discusses the pathogenesis, diagnosis and treatment strategy of urachal carcinoma.

Preoperative CT examination showed neogenesis of the top of the bladder, local protuberant changes, cystoscopy found tumor at the top of the bladder, biopsy pathological indicated adenocarcinoma. The operation was successful, the operation time was about 3 hours, the intraoperative bleeding was about 20 ml, the postoperative pathological indicated moderate differentiated adenocarcinoma and the cutting edge was negative, and the patients was recovered well after the operation.

The diagnosis of urachal carcinoma depends on the clinical manifestations, imaging, cystoscopy and immunohistochemical staining. The treatment of urachal carcinoma includes the resection of umbilicus, urachal and partial bladder, combined with postoperative chemotherapy.
