Metastasis of renal cell carcinoma (RCC) to the bladder is rare. We present a case of a 74-year-old patient with a metachronous, solitary metastasis of RCC to the bladder twenty months after partial nephrectomy and JJ-stent placement for a complex renal tumor. The mechanism of RCC metastasis to the bladder remains controversial, and we believe this case adds support to the drop metastasis theory.
肾细胞癌（RCC）转移至膀胱较为罕见。我们报告一例74岁患者，在因复杂肾肿瘤行部分肾切除及置入输尿管支架20个月后，出现RCC异时性、孤立性转移至膀胱。RCC转移至膀胱的机制仍存在争议，我们认为该病例为肿瘤脱落转移理论提供了支持。
