摘　　要：目的探讨后肾腺瘤（metanephricadenoma，MA）的临床、病理特点及其诊治方法。方法回顾性分析我院收治的8例MA的临床资料，结合文献对其临床特点、影像学表现、病理特征及诊治方法进行讨论。本组男4例，女4例；年龄41～74岁，平均年龄47岁；左肾3例，右肾5例，均为单发。临床表现为腰痛1例，无痛性肉眼血尿1例，其余患者均无明显症状。术前影像（B超、CT）诊断为肾癌。6例行根治性肾切除术（2例开放，4例后腹腔镜），2例行保留肾单位的肾肿瘤切除术（1例开放，1例后腹腔镜）。结果术后病理报告为MA，1例局部伴有乳头状腺癌成分。术后随访6例，随访时间5～57个月（平均25．6个月），均无瘤生存，失访2例。结论MA是一种罕见的肾脏上皮源性肿瘤，影像学表现缺乏特异性，易误诊为肾癌，确诊需依靠病理检查。手术切除为首选治疗方法，预后良好，但应密切随访。Objective To improve the diagnosis and treatment of metanephric adenoma（MA）. Methods The clinical and pathological data of 8 cases of MA were analyzed retrospectively. The 4 males and 4 females aged from 41 to 74 years with an average age of 47 years. One patient had flank pain,and another one had gross hematuria. All of the 8 cases were diagnosed renal tumor by ultra- sonography and CT scans . 6 patients underwent radical nephrectomy and 2 patients underwent par- tial nephrectomy. Results All the patients were diagnosed as MA by pathological study postop- eratively, and foci of papillary carcinoma was observed in one case. 6 cases were followed up for 25.6 months（5 to 57 months） without recurrence or metastasis. Conclusions MA is a very rare primary renal tumor originating from epithelium. Surgical resection is recommended for the treat- ment of MA. Considering the uncertainty of the biological behavior and cellular origin of MA, a long-term follow-up is necessary.
