Patient: Description of the condition (onset time, main symptoms, hospital visited, etc.): Last October, the patient suffered from renal pelvis cancer and had surgery. Recently, the patient was re-examined for multiple masses in the right kidney fossa, lumbar spine metastasis, lumbar pain, peripheral lymph node problems. The blood supply artery of the tumor can be embolized to make the tumor ischemic and necrotic. Non-vascular interventional treatment: the tumor can be punctured under the guidance of ultrasound or CT, and drug injection or cryoablation treatment can be given. For lumbar metastasis, intravertebral cement implantation can be given to help strengthen the stability of the vertebral body and relieve pain.
