肾脏小肿瘤临床与病理资料的分析

目的：探讨肾脏小肿瘤（Small renal mass，SRM）的临床与病理资料的特点。方法回顾性分析2011年哈尔滨医科大学附属肿瘤医院收治的接受根治性切除术或肾部分切除术的36例肾脏小肿瘤患者的临床与病例资料，所有患者的肿瘤应为局限性的实体肿瘤，并且有CT或MRI影像检查报告。结果36例肾脏小肿瘤患者中，肾透明细胞癌32例，乳头状肾细胞癌3例，良性肿瘤1例。接受肾脏根治性切除术的患者34例，仅有2例男性患者接受肾部分切除术。36例肾脏小肿瘤患者肿瘤最大径平均值为2．9 cm。结论在收集到的36例肾脏小肿瘤中病理类型最多的为肾透明细胞癌。36例肾脏小肿瘤患者绝大部分的手术方法为肾脏根治性切除术。

Clinical and pathological characteristics of small renal mass analysis

Objective To explore the clinicopathological characteristics of small renal mass .Methods We reviewed the medical records of patients who had received partial nephrectomy （ PN） or radical nephrectomy （ RN） in 2011 in the tumor hospital of harbin medical university .We identified xxx patients who were treated with PN or RN for renal masses within a size of 4 cm.All small renal masses were localized ,sporadic,solid,and had reports of renal carcinoma measurement by CT or MRI .Results Of the 36 SRMs,there were 32（88.89%）clear cell renal cell carcinoma,3（8.33%）papillary renal cell carcinoma,1（2.78%）begin tumor.Of the 36 patients, 34 patients received radical nephrectomy （ RN） and only 2 male patients received partial nephrectomy （ PN） .The mean tumor size of 36 SRMs was 2.9 cm.Conclusion The majority of 36 SRMs are categorized to clear cell re-nal cell carcinoma by histological type .Most of the 36 patients receive radical nephrectomy （ RN） .
