术前诊断肾癌的肾良性实质肿块的临床特点

Clinical features of renal benign lesions presumed renal cell carcinoma preoperatively

目的探讨术前诊断肾癌的肾良性实质肿块的患者的临床特点。方法回顾性分析中山大学第三医院2001年1月至2011年12月术前影像学诊断肾癌并行肾部分切除或肾根治性切除的患者196例,分析术后病理结果为肾良性实质肿块的32例患者的病理类型、性别、年龄及肿物大小。结果 196例影像学诊断肾癌的患者中,术后病理确诊为良性病变的患者有32例,占16.3%,以肾错构瘤为主,多为女性(P=0.003)、年轻患者(P=0.000),且多见于直径较小的肿块(P=0.001)。结论对于女性、年轻、较小的而影像学诊断肾癌的肾实质性肿块,应注意肾良性病变特别是错构瘤的可能性。

Objective To investigate the clinical features of benign pathologic lesions presumed to be renal cell carcinoma preoperatively.Methods From January 2001 to December 2011,196 patients presumed to be renal cell carcinoma preoperatively were carried out partial nephrectomy or radical nephrectomy.The 32 patients who were proved to be benign lesions were retrospectively analyzed by their pathological type, gender, age and tumor size.Results Of the 196 masses resected,the pathologic examination revealed benign lesions in 32(16.3%).Most benign lesions were in women (P=0.003), younger patients (P=0.000)and smaller mass (P=0.001).Conclusions For women,younger, and smaller renal mass,presumed to be renal cell carcinoma,should be noted the possibility of renal benign lesions especially the angioleiomyolipoma.
