We present two cases of synchronous bilateral renal cell carcinoma treated at Daisan Hospital. Case 1. A 63-year-old man was hospitalized in August 1988 because of right flank pain and fever. Diagnostic imaging showed a large tumor on the right kidney extending into the inferior vena cava, and a smaller one (3.0 cm diameter) on the left middle part. The patient underwent right radical nephrectomy with vena cana resection, and left tumor enucleation at the same time. Histology demonstrated renal cell carcinoma on both sides. The patient is alive without recurrence and with normal renal function 5 years and 1 month after the operation. Case 2. A 62-year-old man was hospitalized in August 1992 because of a feeling of abdominal distension. Diagnostic imaging showed a 3.5 cm diameter tumor on the right kidney, a 6.0 cm diameter tumor on the left kidney. The patient underwent bilateral partial nephrectomy at the same time. Histology demonstrated renal cell carcinoma on both sides. The patient is well without recurrence at 10 months after the operation. Conservative surgery proved effective therapy for patients with bilateral renal cell carcinoma.
我们介绍了在第三医院治疗的两例同步双侧肾细胞癌病例。病例1：一名63岁男性于1988年8月因右侧腰痛和发热入院。诊断性影像学检查显示右肾有一个大肿瘤延伸至下腔静脉，左中部有一个较小的肿瘤（直径3.0厘米）。患者同时接受了右肾根治性切除术及腔静脉切除术和左肿瘤摘除术。组织学检查显示双侧均为肾细胞癌。术后5年1个月，患者存活，无复发，肾功能正常。病例2：一名62岁男性于1992年8月因腹胀感入院。诊断性影像学检查显示右肾有一个直径3.5厘米的肿瘤，左肾有一个直径6.0厘米的肿瘤。患者同时接受了双侧部分肾切除术。组织学检查显示双侧均为肾细胞癌。术后10个月，患者情况良好，无复发。保守手术被证明是双侧肾细胞癌患者的有效治疗方法。
