肾嗜酸性细胞瘤的诊断与治疗

目的:提高对肾嗜酸性细胞瘤的诊疗水平.方法:回顾性分析3例经手术、病理证实为肾嗜酸性细胞瘤患者的临床资料.结果:B超检查均提示肾脏占位性低回声病变.CT检查提示肿瘤直径30～55 mm,高密度C影2例,等密度肿瘤影1例,增强后2例有不同程度的强化.术后随访1～36个月未见肿瘤转移及复发.结论:肾嗜酸性细胞瘤在临床表现和影像学检查上在术前难以与肾癌鉴别,术中冰冻病理可明确诊断.肾嗜酸性细胞瘤可采取肾部分切除术,预后良好.

Diagnosis and Therapy of Renal Oncocytoma

Objective： To improve the levels of diagnosis and management of renal oncocytoma. Methods： The clinical data of 3 patients with renal oncocytoma confirmed by operation and pathology examination were respeetively analyzed. Results： The tumour mass showed low level echo in ultrasound examination. Maximum diameters of the tumours were between 30 mm to 55 mm on CT. 2 cases showed high density and 1 case isodensity and 2 showed image enhancement with CT enhancement injection. 1 was treated by radical nephrectomy and 2 partial nephrectomy. The follow up lasted for 1 to 36 months and without recurrence or metastasis. Conclusion： Renal oncocytoma is difficult to differentiate from renal cancer with clinical manifestations and image examination before the operation.The result of pathology examination during operation may definite diagnosis.Partial nephrectomy is performed to remove the renal oncocytoma and with a good prognosis.
