Two cases of bilateral renal cell carcinoma are reported. The first case is of a 54-year-old male who visited our hospital on March 7, 1984 complaining of colicky pain in his left flank. Intravenous urography showed a large mass in the upper pole of the left kidney causing deformity and dislocation of the upper calyces. There were no remarkable findings in the right kidney. Abdominal CT-scan and arteriography revealed a round and hypervascular tumor with soft tissue mass density in the upper pole of both kidneys. Nephrectomy of the left and segmental resection of the upper pole of the right kidney were performed on April 11, 1984. The second case is a 47-year-old male who visited our hospital complaining of total gross hematuria. Intravenous urography showed a large soft tissue mass at the lower pole of the left kidney. Abdominal CT-scan revealed a large tumor mass associated with central necrosis in the left kidney and also a small tumor lesion at the center of the contralateral kidney. Bilateral nephrectomy was performed on December 19, 1984, and the patient was referred to hemodialysis treatment. The cut section of the nephrectomized right kidney specimen revealed multiple minor accessory tumors. Both patients have been doing well without any evidence of recurrence or metastasis.
报告了两例双侧肾细胞癌病例。第一例是一名54岁男性，于1984年3月7日前来我院就诊，主诉左侧腰部绞痛。静脉肾盂造影显示左肾上极有一巨大肿块，导致上肾盏变形和移位。右肾未见明显异常。腹部CT扫描和动脉造影显示双侧上极有一个圆形且血管丰富的肿瘤，密度为软组织肿块密度。1984年4月11日对左侧进行了肾切除术，对右侧上极进行了部分切除术。第二例是一名47岁男性，因全程肉眼血尿前来我院就诊。静脉肾盂造影显示左肾下极有一巨大软组织肿块。腹部CT扫描显示左肾有一个与中央坏死相关的大肿瘤肿块，对侧肾中央也有一个小肿瘤病变。1984年12月19日进行了双侧肾切除术，患者接受血液透析治疗。切除的右肾标本切面显示有多个小的副肿瘤。两名患者情况良好，无复发或转移迹象。
