To improve the diagnosis and treatment of renal oncocytoma and avoid unnecessary radical nephrectomy. The clinical data of 6 cases of renal oncocytoma diagnosed at the Second Xiangya Hospital Central South University from March 2005 to November 2010, including symptoms, laboratory tests, imaging, style of operation, pathological examination, and follow-up were retrospectively analyzed.There were no special symptoms and obvious abnormal laboratory tests in the patients. Two patients had relatively special imaging. Partial nephrectomy was performed in 2 cases of renal oncocytoma with typical imaging, while radical nephrectomy was performed on other patients because of misdiagnosis. No relapse and metastasis were found in the following 1 to 5 years.Renal oncocytoma is an uncommon benign tumor. Partial nephrectomy or tumor excision can be performed on patients diagnosed with renal oncocytoma according to typical imaging and intraoperative frozen section biopsy. The final diagnosis depends on pathological examination and regular follow-up is imperative for patients with renal oncocytoma.
为提高肾嗜酸细胞瘤的诊断与治疗水平，避免不必要的根治性肾切除术。回顾性分析2005年3月至2010年11月在中南大学湘雅二医院确诊的6例肾嗜酸细胞瘤患者的临床资料，包括症状、实验室检查、影像学检查、手术方式、病理检查及随访情况。患者无特殊症状，实验室检查无明显异常。2例患者影像学表现相对特殊。2例具有典型影像学表现的肾嗜酸细胞瘤患者行保留肾单位手术，其他患者因误诊而行根治性肾切除术。术后1至5年未发现复发及转移。肾嗜酸细胞瘤是一种少见的良性肿瘤。根据典型影像学表现及术中冰冻切片活检确诊为肾嗜酸细胞瘤的患者，可行保留肾单位手术或肿瘤切除术。最终诊断依赖于病理检查，肾嗜酸细胞瘤患者必须定期随访。
