Renal staggered tumor usually grows slowly, and whether it is serious or not needs to be judged according to three factors: the size of the tumor, the location of the growth, and whether there is rupture and bleeding. 1. Tumor size: when the tumor is <4cm and not accompanied by other abnormalities, it usually does not cause damage to kidney tissues, has no conscious symptoms and is not serious. When the tumor is ≥4cm, it may cause pressure on the kidney and surrounding tissues, and requires surgical treatment. 2. Location of growth: When renal malformation tumor grows on the outer side of the kidney, it has little effect on kidney function. However, if the tumor grows in the central part of the kidney, it may compress the cortex and medulla of the kidney, affecting the structure and function of the kidney, and it is necessary to judge whether surgery is needed according to the situation. 3. Whether the tumor ruptures and bleeds: when the tumor does not rupture and bleed, and the size and growth area do not affect the surrounding tissues, it can be followed up for observation. If the tumor ruptures and bleeds, the large amount of bleeding may cause hemorrhagic shock, which is life-threatening, and it is recommended to carry out surgical treatment or interventional therapy in time. Examination of the right kidney misshapen tumor, should be further examination and treatment, so as not to miss the condition.
