Cryoablation is successfully performed as a treatment for small renal cancers. The occurrence of a solitary renal metastasis from lung cancer is an uncommon finding entailing a limited knowledge on the choice of its optimal treatment. We present two patients diagnosed with non-small cell lung cancer, who were initially treated with curatively intended chemoradiotherapy. In the follow-up period, a non-symptomatic solitary renal metastasis was found in both patients. Both received CT-guided cryoablation of their renal metastases. One patient was successfully treated with no relapse, whereas the other patient received re-cryoablation due to development of a new renal metastasis. In both patients, no residual tumour was found at the 3 months' follow-up examination. Whether the minimally invasive procedure of cryoablation is a feasible treatment in the management of solitary renal metastases from lung cancer is still undetermined. The recurrence and incomplete treatment are concerns requiring further research.
冷冻消融术已成功用于治疗小肾癌。肺癌发生孤立性肾转移是一种罕见情况，对其最佳治疗选择的了解有限。我们报告了两名被诊断为非小细胞肺癌的患者，他们最初接受了旨在治愈的放化疗。在随访期间，两名患者均发现无症状的孤立性肾转移。两人均接受了CT引导下的肾转移瘤冷冻消融术。一名患者成功治愈且无复发，而另一名患者因出现新的肾转移而接受了再次冷冻消融术。在3个月的随访检查中，两名患者均未发现残留肿瘤。冷冻消融这种微创手术在肺癌孤立性肾转移的治疗中是否可行仍未确定。复发和治疗不彻底是需要进一步研究的问题。
