Renal tumor is one of the common tumors in the urinary system, and its clinical manifestation has the characteristic unique to the urinary system, and has the systemic and systemic manifestation of the tumor. 1.The common manifestations of urinary system are hematuria: most of the urinary system tumors will appear hematuria, which is the first symptom of patients’ consultation, and it is the symptom that appears after the tumor cells break through the mucosa of renal pelvis. Abdominal pain is caused by tumor growth invading into the renal peritoneum or forming cancer embolus, dislodging into the ureter, causing colic or dull pain symptoms. If the patient can touch the lump outside the body, it means that the tumor is relatively large and grows on the surface of kidney, which is usually in advanced stage, and it is recommended to go to the hospital immediately for further treatment. 2. In vitro manifestations of renal tumor: patients may have fever, fatigue, anemia, nausea, vomiting and other symptoms. Fever is usually caused by tumor cells or other necrotic cells, which become the source of fever, or can be caused by inflammatory stimulation. Anemia can be caused by excessive loss of red blood cells due to hematuria, or by tumor cells producing inhibitory substances that inhibit erythropoiesis and cause anemia. Abnormal liver function due to the production of many hormone-like substances by rectifying cells, which diffuse to the liver causing damage to liver function. Hypertension, because the tumor cells invade the kidney tissue, causing the dysregulation of the renin aldosterone angiotensin system, the body will produce too much aldosterone, causing sodium retention and producing hypertension symptoms. It can also produce symptoms such as rapid blood sedimentation.
