The main symptoms of renal malformation tumor are as follows: first, there is discomfort or pain in the lower back and abdomen; second, some patients will have hematuria, which can be manifested as microscopic hematuria or meatus hematuria; third, there will be a mass in the abdomen. The main reason for consultation is that 60%-80% of patients feel the enlarged kidney; fourth, there is proteinuria, which is the presence of albumin in the urine during routine urine examination; fifth, hypertension, which is caused by tumor compression of the kidney, resulting in renal ischemia and increased renin secretion, resulting in hypertension; sixth, hyperalgesia, which is a progressive decrease in renal function due to the significant reduction of normal renal tissue caused by tumor compression. Malignant tumor is a pseudotumor, not a true tumor, but a combination of errors in the normal arrangement within the organ. It also occurs in normal people and is a benign tumor that rarely becomes malignant, so there is no need to worry too much when this occurs.
