Kidney tumor is a common disease of the urinary system, which progresses slowly in the early stage without any clinical discomfort, but when the tumor grows until abdominal pain, mass and hematuria appear, the condition has lost the best chance of radical treatment, with the improvement of people’s living standard and health checkup, more and more early small kidney cancer is discovered. In the 1940s, Robson, a famous western surgeon, proposed several principles for the radical treatment of kidney cancer, including resection of perinephric fascia, perinephric fat, adrenal gland, kidney and tumor together, ureteral cut at the level of blood vessels, lymph node dissection around kidney vessels, treatment of renal artery first during surgery, do not squeeze the tumor to prevent distant metastasis, and the above total Robson principles. This method has been the mainstay of renal tumor treatment for decades because of its efficacy. However, in patients with isolated kidney, contralateral renal insufficiency, chronic nephritis, or even hypertension, diabetes mellitus or bilateral renal tumors, resection of the affected kidney implies immediate or future chronic renal insufficiency or even uremia after surgery. Recent clinical studies have proved that most early renal tumors tend to squeeze the kidney tissues around the door to form a pseudo envelope, and as long as the tumor is removed outside the envelope, tumor recurrence and metastasis rarely occur, and most of the kidney functions can be preserved, and the chance of tumor recurrence in the preserved kidney is only 1/%. The main reason is to avoid the occurrence of long-term uremia. The popularity of minimally invasive laparoscopic surgery has enabled most patients to avoid the trauma of open surgery and to complete the surgery with only a few keyhole-sized holes in the waist or abdomen, with little trauma and quick recovery and precise efficacy. The use of da Vinci robotic surgery has led to tremendous progress in laparoscopic technology. The da Vinci robotic surgery system is actually a more advanced laparoscope, which has two major advantages over traditional laparoscopy: First, the image is displayed in three dimensions, and the tissue structure in the body is clearly revealed with an abnormal magnification of about 15 times, which facilitates precise operation. Second, the instruments used, such as scissors and forceps, can move in all directions, just like a small, dexterous hand reaching inside the body, making it very easy to suture. On the basis of proficiency in conventional laparoscopy, we have completed more than 200 surgeries in about one year with the newly purchased internationally advanced da Vinci Surgical Systemsi, all of which are major surgeries. The most advanced technology in the world can be enjoyed without leaving Henan. The current charge is only the cost of instrumentation and consumables, about 15,000 to 20,000 yuan more per case than traditional laparoscopy, only half the cost of Beijing Guangzhou and other places. It is believed that as people’s demand for medical and health services increases, robotic surgery will certainly benefit more patients.
