对2006年4月至2010年12月间,因≤4.0 cm肾脏小肿瘤在彩色超声(彩超)或CT指导下应用经皮肾穿刺针对肾脏活检的86例患者的临床资料行同顾性分析.80例穿刺组织可用于确诊,6例因获取组织量不足(出血或组织坏死)无法确诊肿物的病理性质；确诊的80例中,65％(52/80)为恶性肿瘤,35％(28/80)为良性肿瘤.5例患者出现穿刺并发症,47例行手术治疗患者的术后病理检查结果和穿刺检查结果均一致.在影像学指导下对肾脏小肿瘤行针刺活检准确性高,穿刺并发症少,可帮助提供组织学诊断.

Eighty six patients with renal masses≤4.0 cm underwent ultrasound or CT-guided core needle biopsies.The clinical data including the initial biopsy technique,pathologic findings,and the clinical outcome were retrospectively reviewed. Biopsies were failed for diagnosis in 6 cases ( 7％ ) because of necrosis or hemorrhage of the tissue specimens.Of 80 successful biopsies,52 cases (65％) were diagnosed as malignant tumor and 28 cases (35％) as benign. Five patients had biopsy complications (6％),including postoperative hypotension,hemouria and perirenal hematoma. Forty-seven patients underwent surgical extirpation ; the consistency rate of histopathological diagnosis between biopsy and surgical specimens was 100％ in these patients.The results indicate that ultrasound or CT-guided core needle biopsy is an effective and safe procedure for diagnosis of renal small masses.
