We report a case of recurrence of chromophobe renal cell cancer in the ipsilateral ureteric stump eight years later after the primary tumor was excised successfully. Before this detection of the recurrence, the patient had presented with recurrent episodes of hematuria four years after the radical nephrectomy was performed and the investigations were inconclusive. Eventually, the lesion was detected on flexible cystoscopy in the area of the right ureteric orifice protruding in the bladder. Transurethral resection of the tumor surprisingly revealed a chromophobe renal cancer with similar features seen in the primary tumor specimen. The patient underwent robotic-assisted laparoscopic excision of the ureteric stump with a cuff of the bladder and has been recurrence-free for five years on regular surveillance scans.
我们报告一例嫌色细胞肾细胞癌患者，在成功切除原发肿瘤八年后，同侧输尿管残端出现复发。在检测到这种复发之前，患者在根治性肾切除术后四年出现反复血尿，检查结果无定论。最终，在膀胱镜检查中发现病变位于右输尿管口突入膀胱的区域。经尿道肿瘤切除术令人惊讶地发现是一例嫌色细胞肾癌，其特征与原发肿瘤标本相似。患者接受了机器人辅助腹腔镜下输尿管残端及部分膀胱袖状切除术，定期监测扫描显示其已无复发五年。
