In the usual outpatient clinic, we often come across some elderly patients who were found to have tumors, but the treatment of the disease was delayed due to the patients’ fear of surgery; when the disease became serious and obvious symptoms appeared, they turned to the doctor for help, and when they wanted to be operated for treatment, they already missed the optimal time for surgery, and there was no way to return to life, so they could only seek for other treatments, such as chemotherapy, radiotherapy, and so on. Recently, an 83-year-old male patient was admitted to the hospital. Physical examination revealed a space-occupying lesion in the right kidney, with a diameter of about 2.0 cm, and imaging examination considered a tumor in the right kidney. The patient’s family was more active and mobilized the old man to undergo surgery, but the patient himself refused to undergo surgery. Our suggestion was to consider cryoablation of the renal tumor. After communicating with the patient and his family, the patient felt that minimally invasive treatment was acceptable. After thorough preoperative preparation, cryoablation of the right kidney tumor was successfully performed, and the patient recovered well after the operation without any obvious discomfort. Cryoablation therapy can achieve the effect of “getting good tumor elimination with low surgical risk”, because cryoablation only needs to puncture the cryoablation knife to the lesion area under the guidance of ultrasound or CT, and then the ice ball will form a very low temperature below -100℃ locally, which will destroy the cells and lead to ischemic necrosis of tumor tissues so as to kill tumor cells, so it is suitable for a wider range than surgery, so it is more suitable than surgery. Therefore, it is suitable for a wider range than surgery. In addition to limited tumors, patients with distant metastasis and poor physical condition who cannot tolerate surgery can also get the chance to have surgery.
