Malignant kidney tumor
Malignant renal tumors are one of the more common tumors of the urinary system. Common renal tumors in clinical practice include renal cell carcinoma derived from renal parenchyma, nephroblastoma, and transitional cell papillary tumors that occur in the renal pelvis and calves. Hematuria, intra-abdominal mass and back pain are the three main symptoms of the disease. Abdominal masses appear later in adult kidney tumors, but they are the first symptom of renal embryo tumors in young children, so young children with early childhood tumors need to be examined early.
