Malformation tumor is a substantial occupying lesion, which is an autosomal dominant disease. Renal malformation tumor, also known as renal vascular smooth muscle lipoma, is a type of lipoma, consisting of thick-walled vessels, smooth muscle and mature adipose tissue, and can develop singly or in multiple cases. Usually, B-ultrasound and CT examination have a high localization and qualitative diagnosis rate for malignant tumors. It is important to keep your mood relaxed, avoid anger and rage, eat more vegetables and fruits, keep your bowels clear, and eat light, nutritious food instead of too much. Patients with malformation tumor should not overexert themselves at work or in household activities, and should not hold heavy objects or do strenuous exercises to avoid increasing abdominal pressure and causing rupture and bleeding of the tumor. Low-intensity exercises such as long-distance walking can be done frequently. Regularly review the kidney ultrasound and pay attention to the size of the tumor.
