作者将中心型肾肿瘤定义为 :肿瘤周围为正常肾实质包绕 ,外观与触诊不能发现的肾肿瘤。肾单位保留手术对小的、位于肾边缘的肾癌是一种标准的治疗方法。尤其对孤立肾、双侧肾肿瘤或肾功能损害者需作肾切除 ,术后需行血液透析或肾移植的患者 ,肾单位保留手术是唯一的选择。作者
The authors define a central renal tumor as being surrounded by a normal renal parenchyma around the tumor, a kidney tumor whose appearance and palpation can not be found. Nephron-preserving surgery is a standard treatment for small, kidney-located kidney cancers. Especially for isolated kidney, bilateral renal tumors or renal dysfunction who need for nephrectomy, postoperative hemodialysis or kidney transplantation patients, nephron preservation surgery is the only option.
