Is kidney tumour operation major operation

Kidney tumor surgery should be classified as major surgery. Surgery was generally divided into four grades. Kidney tumor surgery was classified as grade 4 surgery. The higher the grade, the greater the difficulty and the higher the risk. If a kidney tumor showed tumor thrombus, the surgery would be more difficult. If it was a normal kidney tumor, radical nephrectomy could be considered. For kidney tumor surgery, open surgery or laparoscopic surgery can be performed. The appropriate surgical method needs to be selected according to the local medical conditions and the location of the tumor. After the affected kidney is removed, the fat tissue around the kidney and lymph nodes should also be removed.
