目的：回顾性评估的安全性和诊断率的小肾肿瘤，并进行穿刺活检的患者转介经皮冷冻treatment.Material和方法：活检进行了119例患者的120个肿瘤（平均直径，2.2厘米）的临床后果。所有程序分为诊断性和非诊断性活检。比较两组患者的各项指标。所有冷冻消融术分为两组：同时活检或不活检。结果：在进行了120次初次和8次重复活检后，44例患者发生了1级眼睑赘生物。6例肿瘤未被诊断，114例被病理诊断。诊断性和非诊断性活检之间无显著变量。9例良性病变通过预先活检避免了不必要的冷冻消融。与活检同时进行的冷冻消融术包括的良性或非诊断性肿瘤明显多于活检后进行的冷冻消融术（15.2%与1.4%;p= 0.01）。结论：对转诊进行冷冻消融的小型肾脏肿瘤进行经皮活检是一种安全的手术，诊断率高。冷冻消融前的病理诊断是必要的，因为良性肿瘤患者可以避免不必要的治疗。
Purpose:To retrospectively evaluate the safety and diagnostic yield of needle biopsy of small renal tumors, and the clinical consequences of performing needle biopsy in patients referred for percutaneous cryoablation before their treatment.Material and methods:Biopsy was performed for 120 tumors (mean diameter, 2.2 cm) in 119 patients. All procedures were divided into diagnostic and non-diagnostic biopsies. Various variables were compared between the two groups. All cryoablation procedures were divided into two groups: procedures with or without simultaneous biopsy. The rates of benign or non-diagnostic tumors in each group were compared.Results:After performing 120 initial and eight repeat biopsies, Grade 1 bleedings occurred in 44 cases. Six tumors were non-diagnostic and 114 were pathologically diagnosed. There were no significant variables between the diagnostic and non-diagnostic biopsies. Unnecessary cryoablation was avoided in nine benign lesions by performing biopsy in advance. Cryoablation performed simultaneously with biopsy included significantly more benign or non-diagnostic tumors than cryoablation performed after biopsy (15.2% vs. 1.4%;p= .01).Conclusions:Percutaneous biopsy of small renal tumors referred for cryoablation was a safe procedure with high diagnostic yield. The confirmation of pathological diagnosis prior to cryoablation is necessary because patients with benign tumors can avoid unnecessary treatment.
