Bowel cancer may metastasize to the kidney of patients, but the possibility is relatively low. Because the development of bowel cancer to a certain extent will have bloodstream metastasis, cancer cells can be transferred to any part of the body in the patient’s bloodstream, but the common bloodstream metastasis is liver metastasis and lung metastasis, and generally metastasis to the patient’s kidney is relatively rare. However, it is possible that the tumor of intestinal cancer increases and can directly invade the kidney or directly invade the ureter of the patient, resulting in ureteral obstruction, and the patient will have hydronephrosis, etc. Especially, tumors appear in the ascending or descending colon, that is, tumors appear in front of the kidney, when the tumor increases, it may directly lead to the invasion of the kidney, or the tumor leads to lymph node metastasis, lymph node enlargement and fusion into a mass, which can also lead to Ureteral invasion or kidney invasion, etc.
