To examine the indication of nephron sparing operations, we searched 31 nephrectomized kidneys with renal cell carcinoma for small associated lesions in the normal-appearing portion of these kidneys. The diameter of the predominant tumors was between 15 and 50 mm. The kidneys were serially sectioned at 5-mm intervals, and all sections were examined microscopically. Two of the 31 kidneys had a small renal cell carcinoma, and four had a small adenoma in the normal-appearing portion. We recommend that the nephron-sparing operation should be is performed limitedly and that radical nephrectomy is yet a standard operation in the presence of a normal contralateral kidney.
为了研究保留肾单位手术的适应证，我们在31例因肾细胞癌而切除的肾脏中，查找这些肾脏外观正常部分的相关小病灶。主要肿瘤的直径在15至50毫米之间。将肾脏以5毫米的间隔连续切片，并对所有切片进行显微镜检查。31例肾脏中有2例在外观正常部分存在小肾细胞癌，4例存在小腺瘤。我们建议保留肾单位手术应有限地开展，并且在对侧肾脏正常的情况下，根治性肾切除术仍是标准术式。
