Pelvic carcinoma

Renal pelvis cancer is a tumor that occurs in the epithelium of the renal pelvis or pelvis, accounting for about 10% of all renal tumors. Interstitial nephritis, long-term use of painkillers, chronic inflammation or stone irritation, and exposure to carcinogens are often the causes of renal pelvic tumors. The age is more than 40 years old, more than male, about 3: 1, there is no significant difference in the incidence of left and right, and those occurring on both sides, accounting for about 2 to 4%. Due to the thin wall of the renal pelvis and abundant lymphoid tissues around it, tumors tend to metastasize to the abdominal aorta and neck lymph nodes; the main organs for blood metastasis are the lungs, liver, and bones.
