A 71-year-old male with history of clear cell renal cell carcinoma (RCC) 6-years status post nephrectomy presented for gross hematuria. Cystoscopy revealed a bulge of the right ureteral orifice, and transurethral resection confirmed RCC metastasis to the ureteral stump. Ureterectomy with bladder cuff excision was performed, and the patient is currently undergoing aggressive imaging surveillance. This is the 57th case of metastasis of RCC to the ureteric stump, and this case occurred beyond baseline surveillance recommendation of five years. Potential mechanisms of metastasis of RCC are reviewed, and RCC surveillance is discussed.
一名71岁男性，有透明细胞肾细胞癌（RCC）病史，肾切除术后6年，因肉眼血尿就诊。膀胱镜检查发现右侧输尿管口隆起，经尿道切除术证实RCC转移至输尿管残端。行输尿管切除术并切除膀胱袖口，患者目前正在接受积极的影像学监测。这是第57例RCC转移至输尿管残端的病例，且该病例发生在超过五年的基线监测建议时间之后。本文回顾了RCC转移的潜在机制，并讨论了RCC监测。
