摘要/Abstract

摘要： 目的探讨后肾腺瘤(MA)的临床表现、影像学特点、病理学特征、治疗方法和预后,以提高对MA的诊断和治疗水平。方法回顾性分析南昌大学第一附属医院自2011年5月至2019年1月收治的经病理学确诊的9例MA患者的临床资料,对其临床表现、影像学特点、组织学和免疫组化特征、治疗方法以及预后进行总结、分析和讨论。结果本组9例,其中腰痛者1例,腰部不适者2例,腰痛合并红细胞增多症1例,其余5例均为体检发现;肿瘤位于左侧5例,右侧4例;肿瘤平均直径为4.3(1.7~6.7)cm;行腹腔镜肾部分切除术(LPN)者7例,行腹腔镜根治性肾切除术(LRN)者2例;所有患者术后病理诊断均为MA;平均随访时间为43(5~97)个月,患者均无复发或转移征象。结论 MA是一种罕见的肾脏肿瘤,临床表现和影像学特征对诊断有一定帮助,确诊主要依赖病理学,预后一般良好,但需定期随访。

Abstract: Objective To explore the clinical manifestations, imaging features, pathological features, treatment and prognosis of metanephric adenoma(MA)in order to improve the diagnosis and treatment of MA. Methods The clinical data of 9 MA patients confirmed by pathology in The First Affiliated Hospital of Nanchang University from May 2011 to January 2019 were analyzed retrospectively, and their clinical manifestations, imaging characteristics, histological and immunohistochemical characteristics, treatment methods and prognosis were summarized, analyzed and discussed. Results A total of 9 MA patients were enroued in this study, including 1 case of low back pain, 2 cases of low back discomfort, 1 case of low back pain complicated with polycythemia, and the other 5 cases were found by physical examination. The tumors were located on the left side in 5 cases and on the right side in 4 cases. The mean diameter of the tumors was 4.3(1.7-6.7)cm. Laparoscopic partial nephrectomy(LPN)was performed in 7 cases and laparoscopic radical nephrectomy(LRN)in 2 cases. All cases were pathologically diagnosed as MA. The mean follow-up time was 43(5-97)months, and there were no recurrence or metastasis in all cases. Conclusion MA is a rare renal tumor. Its clinical manifestations and imaging features are helpful for diagnosis, but the diagnosis mainly depends on pathology. The prognosis of MA is generally good, but regular follow-up is needed.
