Metastasis-directed therapy of small solitary foci of metastatic renal cell carcinoma has been associated with improved survival. Percutaneous resection of tumors in the upper tract urinary system has been widely used for treatment of localized urothelial carcinoma, however, its role in renal cell carcinoma has not been described. Herein, we present the first case of patient undergoing percutaneous resection of renal cell carcinoma in the contralateral renal pelvis.
This is a case report describing the diagnosis, management and surgical approach to renal cell carcinoma recurrence in the contralateral renal pelvis.
Our patient was a 75-year-old male with a history of renal cell carcinoma status post radical nephrectomy who developed a solitary 2 cm recurrence in the contralateral renal pelvis, which was found after he presented with gross hematuria. He underwent successful percutaneous resection of this recurrence with final pathology showing clear cell renal cell carcinoma.
We present the first case of renal cell carcinoma recurrence in the contralateral renal pelvis treated with percutaneous resection.
小的孤立转移灶的转移性肾细胞癌的转移导向治疗与生存改善相关。上尿路系统肿瘤的经皮切除术已广泛用于治疗局限性尿路上皮癌，然而，其在肾细胞癌中的作用尚未描述。在此，我们报告首例接受对侧肾盂肾细胞癌经皮切除术的患者。
这是一例描述诊断、管理和手术方法的病例报告，涉及对侧肾盂肾细胞癌复发。
我们的患者是一名 75 岁男性，有肾细胞癌病史，行根治性肾切除术，在出现肉眼血尿后发现孤立的 2 厘米对侧肾盂复发。他成功地接受了经皮切除术切除了这个复发灶，最终病理显示为透明细胞肾细胞癌。
我们报告首例经皮切除术治疗对侧肾盂肾细胞癌复发的病例。
