目的：我们描述了我们的试点经验，经皮冷冻消融术的肾肿块使用实时sonography.Materials和方法：三例。4个肾脏中有4个肾脏肿块，通过计算机断层扫描或磁共振成像标准进行对比剂给药后增强。在全身麻醉下，在实时超声引导下，将17号冷冻针插入肾肿瘤中进行肾肿瘤冷冻消融术。所有患者在冷冻消融术后6 ~ 7周进行横断面成像随访。结果：无围手术期并发症。所有患者在手术后24小时内出院回家，术后疼痛通过口服降血压药物控制。随访横断面成像显示，病变从初始治疗前体积平均缩小63% +/- 15%。重要的是，没有一个病变显示对比增强计算机断层扫描或磁共振成像criterions.Conclusions：我们的初步经验表明，经皮，超声引导下的肾肿瘤冷冻消融术可以是一种安全的方法治疗肾肿块。
Purpose: We describe our pilot experience with percutaneous cryoablation of renal masses using real-time sonography.Materials and Methods: Three patients presented. with 4 renal masses in 4 kidneys, which enhanced with contrast administration by computerized tomography or magnetic resonance imaging criteria. Renal neoplasm cryoablation was performed using general anesthesia with 17 gauge cryoneedles percutaneously placed into the renal tumor under real-time sonographic guidance. Followup cross-sectional imaging was performed 6 to 7 weeks following cryoablation in all patients.Results: No perioperative complications were noted. All patients were discharged home within 24 hours of the procedure and postoperative pain was controlled with oral normarcotic medications. Followup cross-sectional imaging indicated that the lesions shrank an average 63% +/- 15% from initial pretreatment volume. Importantly none of the lesions showed contrast enhancement by computerized tomography or magnetic resonance imaging criteria.Conclusions: Our initial experience shows that percutaneous, sonographically guided renal neoplasm cryoablation can be a safe method for treating renal masses.
