目的：探讨肾嗜酸细胞瘤的诊断和治疗。方法：回顾分析我院2003-2009年间收治11例肾嗜酸细胞瘤的临床资料，结合文献对肾嗜酸细胞瘤的诊断及治疗进行复习讨论。结果：本组11 例患者中，年龄为26-75岁，男性7例，女性4例。合并透明细胞癌者 1例，术前误诊为肾上腺肿瘤者1例。7例行根治性肾切除术者，4例行肾部分切除术。术后随访11个月-7年未见肿瘤转移或复发。结论：肾嗜酸细胞瘤倾向于良性肾实质性肿瘤，临床表现无特异性，确诊需临床表现、影像学检查与病理学检查相结合。治疗首选保肾手术，但应注意并发恶性肿瘤的可能，加强随访。

英文摘要:

Objective: To evaluate the diagnosis and treatment of renal oncocytoma. Methods: Retrospective analysis of the clinical data of 11 cases of renal oncocytoma admitted to our hospital from 2003 to 2009, and discussed its diagnosis and treatment with literature reviewed. Results: 11 Patients, including 7 males and 4 females, ware 26 to 75 years old. There were 1 case with Clear cell carcinoma, 1 case misdiagnosed as adrenal gland tumors, 1 case misdiagnosed as renal cell carcinoma and had done radical nephrectomy, and other 10 patients had done partial nephrectomy. No recurrence or metastasis was reported later from 11 months to 7 years. Conclusions: It tends to be benign renal tumor. It has no specific features on the Clinical manifestations. The diagnosis should be established on symptom, physical sign, imaging and pathology. Nephron-sparing surgery should be done , and the follow-up is important because the tumor may be combined with malignancy tissues.
