Gulou Hospital has always taken minimally invasive treatment as its main direction for a long time. In recent years, we have carried out radiofrequency treatment for kidney tumors. The radiofrequency ablation of kidney cancer we carry out broadly includes two kinds. One is laparoscopic-assisted cold circulation radiofrequency ablation. The main indications are: (1) kidney cancer occurring in anatomical or functional isolated kidney, or patients who have undergone radical nephrectomy on the opposite side and now have metastasis on the other side; (2) bilateral multiple kidney cancer; (3) metastatic kidney cancer; (4) kidney cancer patients with renal insufficiency; (5) kidney cancer with certain benign diseases on the opposite side of the kidney, such as kidney stone, chronic pyelonephritis or other diseases that may lead to deterioration of kidney function (such as hypertension, diabetes, renal artery stenosis, etc.); (6) kidney cancer with certain benign diseases on the opposite side of the kidney. renal artery stenosis, etc.); (6) patients with minimally invasive treatment requirements who are unwilling to surgically remove the tumor; (7) patients whose tumors are adjacent to large blood vessels in the kidney portal, ureter, intestinal canal, liver, spleen and other important organs and need laparoscopic assistance for adequate exposure. Further, it is percutaneous radiofrequency ablation. In fact, this is the ultimate direction of minimally invasive treatment. However, not all patients are suitable for percutaneous radiofrequency ablation. If the tumor is located in the dorsolateral part of the kidney, there are no important organs around and the tumor is not too large, of course, percutaneous radiofrequency ablation can be chosen. We use ultrasound localization or PET-CT localization when performing percutaneous RF ablation. This requires a good team with close cooperation and skill to guarantee it.
