Metachronous metastasis from renal cell cancer (RCC) after radical surgery can occur in up to one third of patients, most commonly from clear cell RCC. Metastatectomy is a suitable management strategy in oligometastatic disease. We present the case of a 78-year-old woman who developed haematuria 2 years after left radical nephroureterectomy for a pT3aNx chromophobe RCC (ChRCC). No adjuvant therapy was given and surveillance to date was negative for metastasis. A large solitary bladder tumour which was resected, and histopathology confirmed intravesical recurrence of the ChRCC. We present this case and discuss intravesical recurrences of renal cancer.

肾癌（RCC）根治性手术后异时性转移在多达三分之一的患者中可能发生，最常见于透明细胞RCC。转移灶切除术是寡转移疾病的一种合适治疗策略。我们报告一例78岁女性病例，该患者在接受左肾输尿管根治性切除术治疗pT3aNx嗜色细胞肾癌（ChRCC）2年后出现血尿。未给予辅助治疗，迄今为止的监测未发现转移。切除了一个大的孤立性膀胱肿瘤，组织病理学证实为ChRCC膀胱内复发。我们展示此病例并讨论肾癌的膀胱内复发情况。
