In mild cases of renal malformation tumor, the tumor is small, about 1cm-4cm, and does not require treatment, and daily attention to dietary care is sufficient. The diet should be light, with less indigestible food, more nutritious food and more fresh fruits and vegetables. To avoid tumor enlargement and compression of neighboring organs, which may cause adverse symptoms, close follow-up should be performed. If the tumor is larger than 4cm, it should be treated. The treatment methods are mainly surgical resection and kidney transplantation method. Different methods are applicable to different patients, and patients should choose according to their own situation. How to treat renal malformation tumor? 1. Embolization: Those who bleed should act pulse embolization. After treatment, the patient’s bleeding is stopped, but the tumor does not shrink. To remove the tumor, surgery should be performed on the basis of protecting renal function or choose renal artery branch embolization treatment. 2.Surgery to preserve renal unit: Some patients with mild disease do not need treatment, but after a period of time, when the tumor increases from below 4cm to 5cm, surgery should be considered. The common surgery is enucleation. This surgery mainly removes the tumor at the edge of the kidney to achieve the purpose of treating the disease. 3.Nephrectomy: It is suitable for patients with heavy disease and large tumor. If the lesion is bilateral, the first important factor that should be considered in the treatment is to preserve the kidney unit. A few patients with enlarged tumors invading other organs, such as lymph nodes, will have malignant lesions, and surgery should be performed to remove the kidney to cure the disease radically. 4.Kidney transplantation or hemodialysis: It is the most effective treatment to cure the disease, but there is a prerequisite for transplantation, that is, there is a suitable kidney that does not reject with the patient. Kidney transplantation is suitable for those with renal failure, those who have failed with surgical treatment, those with tumor rupture and bleeding and those with bilateral lesions.
