From Sept. 1991 to Jan. 1999, we performed partial nephrectomy on 7 patients with renal cell carcinoma. The indication was imperative for 3 patients, and elective for 4 patients. The 3 imperative cases consisted of bilateral renal cell carcinomas, a polycystic kidney disease and a contralateral atrophic kidney. All 4 patients with elective indication revealed renal cell carcinoma with a normal functioning contralateral kidney. The tumor size ranged from 1.3 cm to 6.0 cm (2.7 cm on average). The mean clamping time of renal artery was 22 minutes and mean blood loss was 400 ml. The pathological stage was pT1a in 6 patients and pT1b in one patient. Postoperative follow-up ranged from 4 months to 92 months (mean: 43 months). One patient with bilateral renal cell carcinoma died of metastases to the lungs and brain at 25 months postoperatively. The remaining 6 patients are alive without recurrence and metastasis. We obtained a good postoperative course in our selected patients with low stage. Thus it was considered that partial nephrectomy is effective against small renal cell carcinoma.
1991年9月至1999年1月，我们对7例肾细胞癌患者实施了部分肾切除术。其中3例为迫切需要手术，4例为选择性手术。3例迫切需要手术的病例包括双侧肾细胞癌、多囊肾病和对侧萎缩肾。4例选择性手术的患者均为对侧肾功能正常的肾细胞癌。肿瘤大小为1.3 cm至6.0 cm（平均2.7 cm）。肾动脉平均阻断时间为22分钟，平均失血量为400 ml。病理分期6例为pT1a，1例为pT1b。术后随访时间为4个月至92个月（平均43个月）。1例双侧肾细胞癌患者术后25个月死于肺和脑转移。其余6例患者存活，无复发和转移。我们对所选的低分期患者术后过程良好。因此，认为部分肾切除术对小肾细胞癌有效。
