肾嗜酸细胞腺瘤诊治分析(附26例报告)

Diagnosis and treatment of renal oncocytoma(report of 26 cases)

目的提高肾嗜酸细胞腺瘤的诊治水平。方法回顾性分析1997年至2010年26例肾嗜酸细胞腺瘤患者的临床资料。20例行肾切除,6例行肾部分切除。结果 26例中,25例诊断考虑肾癌,4例发现有浸润,21例肿瘤直径小于4cm。随访1～156个月,均无转移与复发。结论部分肾嗜酸细胞腺瘤会有浸润,但不影响其良性性质。临床上肾嗜酸细胞腺瘤与肾癌鉴别困难,结合临床表现、CT和B超等影像学检查综合判断,在一定程度上有助于提高其诊断率,最后确诊有赖于病理学及免疫组化检查。治疗以保留肾单位手术为首选。

Objective To improve the diagnosis and treatment of renal oncocytoma.Methods Clinical dates of 26 cases of patients with renal oncocytoma treated from 1997 to 2010 were retrospectively analyzed.Nephrectomy was performed in 20 cases and enucleation in 6 cases.Results Of 26 cases,25 patients were diagnosis as renal carcinoma.All the pathological reports were renal oncocytoma.Infiltration was found in 4 cases and the diameters of 21 cases were less than 4 cm.With 1-156 months follow-up,no recurrence and metastasis was found.Conclusions Infiltration can be found in some renal oncocytoma,but these tumors are still benign.Renal oncocytoma is difficult to tell from renal cancer,but analyzing clinical manifestation,CT and ultrasound can be helpful in some degree.The final diagnosis can be established on histopathologic and immunohistochemical studies.The treatment of renal oncocytoma should be heminephrectomy or enucleation of the tumor.
