Renal pelvis cancer
Renal pelvic cancer is a tumor that occurs in the epithelium of the renal pelvis or calyx, accounting for about 10% of all renal tumors. Interstitial nephritis, long-term use of painkillers, chronic inflammation or stone stimulation, and contact with carcinogens are often the causes of renal pelvic tumors. Most patients are over 40 years old, and there are more men than women, about 3:1. There is no significant difference in the incidence of left and right sides. Those who occur on both sides at the same time account for about 2-4%. Because the renal pelvis wall is thin and surrounded by abundant lymphatic tissue, the tumor is easy to metastasize to the para-aortic and cervical lymph nodes; the main organs for hematogenous metastasis are the lungs, liver and bones.
