作者在大动物模型中研究射频技术治疗小肾癌的有效性和安全性。在 7头猪的正常肾中产生 2 2处病变。通过开放暴露肾脏或超声引导下经皮应用射频能量。以灰阶和能量超声检测病变的变化。在肾与肾周筋膜之间注入盐水 (水间隔 )或ＣＯ2 (气间隔 )避免周围组织的热损伤。超声和病理
The authors study the effectiveness and safety of radiofrequency technology in the treatment of small renal cell carcinoma in a large animal model. There were 22 lesions in the normal kidney of 7 pigs. Transdermal application of RF energy through open exposure to the kidneys or ultrasound. Changes of lesions were detected by gray scale and energy ultrasound. Saline (water space) or CO2 (air space) is infused between the kidney and the perirenal fascia to avoid thermal damage to the surrounding tissue. Ultrasound and pathology
