摘要
目的提高肾嗜酸细胞腺瘤(renal oncocytoma,RO)的诊疗水平。方法回顾分析13例RO患者临床资料。13例患者中,男4例,女9例;肿瘤单发12例,单侧多发1例;肿瘤最大直径为1.0～6.9cm,平均3.3cm;肿瘤位于左肾上极2例,左肾中极2例,左肾下极3例,右肾上极4例,右肾中极1例,右肾下极1例。所有患者术前均行B超、IVU检查,12例行CT检查,3例行MRI检查。结果 12例术前诊断为肾癌,1例考虑为RO。13例中8例行根治性肾切除术,5例行肾部分切除术。术后病理均证实为RO。随访1～183个月无肿瘤复发或转移。结论 RO是一种临床少见的良性肿瘤,术前确诊较困难,与肾癌较难鉴别,诊断有赖于病理组织学和免疫组化检查,保留肾单位手术为首选治疗方法。
Objective To improve the diagnosis of constrictive renal oncocytoma（RO）.Methods The clinical data of 13 cases of renal oncocytom were retrospectively analyzed.Of these patients,4 were male,and 9 were female,12 had single tumor in one kidney and 1 had multiple lesions in one kidney,the diameter of the tumors were 1.0-6.9 cm,3.3 cm averagely,with 2 cases in upper pole,2 in middle pole,and 3 in lower pole of left kidney;Also,there were 4 cases in upper pole,1 in middle pole,and 1 in lower pole of right kidney.Before the operations,all the patients underwent B-ultrasonography and IVU,12 received CT scaning and 3 received MRI.Results However,only 1 in all of the cases was determined preoperatively.8 patients received radical nephrectomy,and 5 received partial nephrectomy.All cases were confirmed as renal oncocytoma by postoperative pathology.Conclusions Renal oncocytoma is a benign tumor and difficult to distinguish with renal cell carcinoma.The diagnosis of renal oncocytoma must depend on histopathological and immunohistochemical.Nephron-sparing surgery such as partial nephrectomy is valuable for such cases.
