The use of da Vinci robot-assisted laparoscopic technology is the most important progress in international minimally invasive surgery in the past 10 years, and is the latest product of the perfect combination of minimally invasive surgery, instrument industry and information technology. Its greatest technical advantage lies in the dexterous movement beyond the reach of the human hand and the stereoscopic vision beyond the human eye, realizing “fine”, “precise” and “accurate” surgical operations. “It has achieved a win-win situation for patients with urological tumors, especially those with kidney cancer and prostate cancer, i.e., prolonging the survival time and improving the quality of life. The Department of Urology of Changhai Hospital is one of the earliest and one of the most numerous units in China to carry out da Vinci robot-assisted laparoscopic surgery in urology. Prof. Linhui Wang is one of the first experts qualified to operate da Vinci robot-assisted laparoscopic surgery, and has accumulated rich experience in da Vinci robot-assisted laparoscopic surgery for kidney cancer and prostate cancer, which improves the overall oncological, functional and traumatological aspects of Specifically: 1) complete removal of tumor, more effective tumor control, and longer postoperative survival time; 2) more preservation of functions (kidney cancer: kidney function, endocrine function; prostate cancer: urinary control function, sexual function), and improvement of patients’ postoperative quality of life. postoperative quality of life. 3. Further reduce surgical trauma, decrease surgical complications, shorten hospitalization time, accelerate postoperative recovery and return to work as soon as possible.
