目的探讨超声引导经皮微波消融肾肿瘤的安全性和临床疗效.方法 22例肾肿瘤患者(22个病灶),其中肾癌18例,肾血管平滑肌脂肪瘤3例,肾嗜酸细胞腺瘤1例.肿瘤直径1.0～3.8 cm.治疗时在超声引导下将水冷式微波天线植入肿瘤内,瘤周放置测温针实时监测温度,肿瘤直径小于2 cm者使用一根微波天线,肿瘤直径大于2 cm者使用2根微波天线.微波消融后3 d内行超声造影观察有无残存肿瘤,造影无肿瘤残存者治疗后1、3、6个月,随后每6个月行增强CT/MR或超声造影评价肿瘤的治疗效果.结果 20例病灶在一次消融后完全坏死,2例病灶在二次消融后完全坏死,微波消融无严重并发症出现,随访期内未发生肿瘤复发、转移.结论超声引导经皮微波消融肾肿瘤安全有效,副作用小,是治疗局限性肾肿瘤的有效方法.

Objective To evaluate the safety and efficacy of ultrasound-guided percutaneous microwave ablation of renal neoplasms.Methods Twenty-two patients with pathologically proven renal neoplasms(18 renal cell carcinoma,3 renal angiomyolipoma,1 oncocytoma)with diameters of 1.0 to 3.8 cm were treated by microwave ablation.Cooled-shaft needle antenna was percutaneously inserted into the tumors under ultrasound guidance.One antenna was used for tumors less than 2 cm,two antennas were used for tumors larger than 2 cm.One thermal couple was placed adjacent to the tumor monitoring temperature in real-time during ablation.Immediate treatment efficacy was assessed by contrast-enhanced ultrasound within 3 days after ablation.Short-term efficacy was assessed by contrast-enhanced CT and/or contrast-enhanced ultrasound at 1,3,6 months and every 6 months thereafter.Results Twenty tumors were completely ablated in a single session,2 tumors were completely ablated in 2 sessions.No complications occurred.No residual tumor or recurrence was observed during follow-up.Conclusions Ultrasound-guided pereutaneous microwave ablation appears to be a safe and effective technique for the management of renal neoplasms in selected patients.
