A 67-year-old woman was admitted for intermittent gross hematuria. Her medical history included a right colectomy for cancer of the ascending colon and removal of metastatic nodes adjacent to the right internal iliac vessels, respectively at 63 and 65 years of age. Cystoscopy detected a semi-pedunculated, nonpapillary (3.5-4 cm diameter) tumor situated above the right ureteral orifice. The histological evaluation of the resected specimen revealed metastatic colonic adenocarcinoma. The history and pathological findings were consistent with a mechanism of endoluminal implantation of adenocarcinoma of the large bowel to the bladder via the right ureter.
一位 67 岁女性因间歇性肉眼血尿入院。她的病史包括 63 岁时因升结肠癌行右结肠切除术和 65 岁时切除右侧髂内血管旁转移性淋巴结。膀胱镜检查发现一个位于右输尿管口上方的半息肉状、非乳头状（3.5-4cm 直径）肿瘤。切除标本的组织学评估显示转移性结肠腺癌。病史和病理发现符合一种机制，即大肠腺癌通过右输尿管向膀胱腔内植入。
