In recent years, most patients with kidney cancer are due to asymptomatic kidney tumors or adrenal tumors discovered during health checkups, and these patients account for more than 70 to 80 percent of the total number of patients. The most common symptom for a small number of patients with huge tumors is back pain or finding an abdominal mass. For these patients with huge tumors, comprehensive treatment is needed. If physical condition allows, surgery is still recommended to remove the primary lesion, and then adjuvant medication will be administered later. The surgical treatment of giant tumors was basically based on open surgery in the past, which required large surgical incisions, usually 30 cm long, and the postoperative patients had obvious pain, slow recovery and were prone to long-term bed-ridden complications. In recent years, our treatment group has successfully performed more than 10 cases of minimally invasive surgery for giant renal tumors and adrenal tumors using laparoscopy. The largest diameter of tumors in minimally invasive treatment was 26 cm, including giant renal tumors and adrenal pheochromocytoma, etc. All patients recovered well after surgery, and the largest surgical incision was only 12 cm (for removing the cut tumors).
