Kidney cancer is one of the three common urological tumors. The basic treatment is based on radical kidney cancer surgery, and kidney-conserving surgery can be performed for tumors below 4CM according to specific conditions. (1) Radical kidney cancer surgery methods: either laparoscopic or traditional surgical methods can be used. In recent years, we have combined certain laparoscopic techniques with traditional surgery to carry out radical surgery for kidney cancer with small incisions, because even for laparoscopic surgery, three or four holes need to be made, and the total length of the incision has to be at least 6~8cm to remove the complete kidney (required for pathological section), while we can complete radical surgery for kidney cancer in an incision of about 7cm. In this way, i.e., we avoid the unfavorable factors such as hypercapnia that occur during laparoscopic surgery, the operation time is shorter than laparoscopy, and the bleeding volume is comparable; the only regret is that patients who are too obese are not suitable for this type of surgery. The only regret is that patients who are too obese are not suitable for this type of surgery. This surgery is the leading one in China. 2) Kidney preserving surgery: The aim of this type of surgery is to preserve kidney units as much as possible on the basis of ensuring tumor removal. However, both laparoscopic and traditional open surgery require intraoperative blockage of the renal artery, a move that, although reducing the amount of bleeding, has a significant impact on the function of the preserved kidney to varying degrees. With skilled surgical techniques, we have carried out kidney-preserving surgery without blocking the renal artery in recent years, preserving the kidney units of non-tumor causes as much as possible and realizing the true sense of minimally invasive rather than minimally invasive on surgical incision.
