目得：为了评估结果的初步和目前的技术经皮肾冷冻治疗，包括长期的成像outcomes.MATERIALS和METHODS：计算机断层扫描（CT）引导下经皮肾冷冻治疗进行了49个群众在48个门诊和程序舒适度为每个。其中原发性肾细胞癌36例，嗜酸细胞瘤3例，血管平滑肌脂肪瘤1例，肾脏炎性病变6例，良性病变2例，结肠癌转移1例。所有并发症根据标准化criterions.Results分级：患者只接受局部麻醉和中度镇静过程中的程序，并在4-6小时内出院，最小的不适。所有冷冻治疗区域在消融过程中通过CT明确定义为平均直径为5.3 cm的低密度冰，覆盖平均肿瘤大小为3.3 cm。平均消融区直径随时间推移显著减小（P
PURPOSE: To assess the results of initial and current techniques for percutaneous renal cryotherapy, including long-term imaging outcomes.MATERIALS AND METHODS: Computed tomography (CT)-guided percutaneous cryotherapy was performed on 49 masses in 48 outpatients and procedure comfort noted for each. These 49 masses included 36 primary renal cell carcinomas (RCCs), 3 oncocytomas, 1 angiomyolipoma, 6 renal inflammatory lesions, 2 benign parenchymal changes, and 1 colon cancer metastasis. All complications were graded according to standardized criteria.RESULTS: Patients received only local anesthesia and moderate sedation during the procedure and were discharged with minimal discomfort within 4-6 hours. All cryotherapy zones were well defined by CT during ablation as hypodense ice with an average diameter of 5.3 cm, covering an average tumor size of 3.3 cm. Average ablation zone diameters showed significant reduction over time (P
