摘要 1989年12月～1997年4月行保留肾组织手术治疗肾癌14例，其中双侧肾癌5例，对侧肾有病变或潜在功能受损的肾癌3例，对侧肾正常肾癌6例。肿瘤平均直径2.9cm，病理分期为T₁ 、T₂ 。14例中5例行剜出术，9例行肾部分切除术。本组术后无外科并发症，平均随访46.6个月，无瘤存活12例，无局部复发。存活时间超过7年者2例，5年者4例，3年者1例，1年者2例，半年者3例。保留肾组织手术是早期局限性肾癌的有效治疗方法，可用于对侧肾正常、肿瘤体积较小的早期肾癌的治疗。

    Abstract From December 1989 to April 1997, nephron-sparing surgery wasperformed for 14 patients with renal cell carcinoma, of which there were 5 patients withbilateral tumors, 3 with unilateral tumor and a damaged opposite kidney, and 6 withunilateral tumor and a normal opposite kidney. The mean size of the tumors was 2.9 cm. Allthe tumors were proved to be stage T₁ or T₂ . Of the 14 patients, 5underwent tumor enucleation and 9 underwent partial nephrectomy. There were no postoperative surgical complications. Twelve patients (83.3%) were tumor-free at a meanfollow-up of 46.6 months. Among them, 2 have survived more than 7 years, 4 more than 5years, 1 more than 3 years, 2 more than 1 years, and 3 more than half a year. There wereno local tumor recurrences. Nephron-sparing surgery is effective and safe for patientswith localized low stage renal cell carcinoma. It could be indicated for selected patientswho present with a small localized unilateral tumor and a normal contralateral kidney.
