Renal malformation tumor is a medium to large size surgery in kidney surgery, which has a certain degree of difficulty. Renal malformation tumor is a difficult surgery in kidney surgery. For patients with small size of renal malformation tumor, simple removal of the tumor is possible. However, for patients with large renal malformation tumor, it is necessary to remove one side of the kidney, which is a medium-large scale surgery, and the surgical requirements are relatively high. Patients with renal malformation tumors are generally benign tumors with slow growth rate and clear boundaries, which will not spread and metastasize, and can generally be cured through surgical resection. However, if renal malformation tumor is not treated in time, with the increase of volume and the prolongation of time, there is a possibility of malignant transformation. Therefore, it is recommended that patients with renal malformation tumor actively cooperate with physicians for surgical treatment, so as not to delay the condition and cause adverse consequences.
