Intermittent hematuria cannot determine the stage of kidney cancer, and the severity of hematuria is not related to the size and stage of tumor.
Typical symptoms of kidney cancer include hematuria, pain and abdominal mass, which is called “triad of kidney cancer”, besides, some patients have atypical clinical symptoms or even no symptoms.
Currently, kidney staging is mainly based on Robson and TNM staging.
Robson staging: Stage I refers to the growth of tumor limited to the renal peritoneum. Stage II refers to the tumor has penetrated the renal peritoneum and invaded the perirenal fat, but still confined to the perirenal fascia. Stage III tumors are those that have invaded the renal vein or local lymph nodes, with or without involvement of the inferior vena cava and perirenal fat. Stage IV means that the tumor has undergone distant metastasis or invaded adjacent organs.
TNM staging: it is based on the size of the tumor, the number of lymph nodes involved and whether there is metastasis, thus determining the staging. t refers to the size of the primary lesion of the tumor, n refers to the distant metastatic lymph nodes, and m refers to the presence or absence of distant metastasis.
When you feel unwell, you should go to the hospital immediately for relevant examinations, such as ultrasound, CT, etc., and be treated under the guidance of the doctor.
