Abstract：
Although the gold standard in the management of kidney tumors is surgical treatment, thermal ablation methods are a viable therapeutic option for patients with small (<4 cm) renal masses who are poor surgical candidates. The aim of this study was to compare the technical success, primary efficacy and complication rate of percutaneous radiofrequency and microwave ablation in the treatment of small renal masses. A retrospective analysis of consecutive patients with small renal masses treated with radiofrequency or microwave ablation between December 2017 and January 2022 was conducted. Response to the ablative therapy was assessed on contrast-enhanced computed tomography examination after 3 months. Ablations of 44 kidney lesions were performed in 43 patients. Sixteen lesions were treated with radiofrequency and 28 with microwave ablation. Both methods were associated with high technical success (100%). Primary efficacy rates of radiofrequency and microwave ablation were 81.3% and 89.3%, respectively. Ablation-related complications were noted only in the patients treated with microwave ablation (18.5%), all of them being low grade (Clavien-Dindo 1 and 2). Radiofrequency and microwave ablation exhibited comparable efficacy in the treatment of small renal masses. Microwave ablation was associated with a comparatively higher number of complications.
摘要：
虽然治疗肾脏肿瘤的金标准是手术治疗，热消融方法是一种可行的治疗选择,适用于肾脏小肿块(<4cm)患者,但手术治疗效果较差.这项研究的目的是比较技术上的成功，经皮射频和微波消融治疗肾脏小肿块的主要疗效和并发症发生率。回顾性分析2017年12月至2022年1月期间接受射频或微波消融治疗的肾脏小肿块患者。3个月后，通过对比增强计算机断层扫描检查评估对消融治疗的反应。43例患者进行了44例肾脏病变的消融。射频治疗16个病灶，微波消融治疗28个病灶。两种方法均具有较高的技术成功率(100%)。射频和微波消融的主要有效率分别为81.3%和89.3%,分别。仅在微波消融治疗的患者中发现消融相关并发症（18.5%），所有这些都是低等级的(Clavien-Dindo1和2)。射频和微波消融在治疗小肾脏肿块方面具有相当的疗效。微波消融与相对较高数量的并发症相关。
