Treatment of uroepithelial carcinoma: Firstly, if the health condition is relatively good, there is no metastasis to other organs in distant places, and the tumor is confined to the uroepithelium, it is recommended to choose radical surgery as far as possible to remove the tumor. For example, uroepithelial cancer of renal pelvis requires unilateral total resection of kidney, ureter and part of bladder. Tumors of the bladder may be treated with transurethral cystectomy, partial cystectomy or total cystectomy. Ureteral tumors require ureteral resection of the tumor segment and ureteral end-to-end anastomosis, or ureteral skin stoma and other treatments. Second, postoperative chemotherapy. Uroepithelial cancer tumor has certain efficacy to bladder instillation chemotherapy drugs. For example, after radical pyelonectomy, bladder perfusion chemotherapy is needed. The drugs commonly used are mitomycin 20mg, bladder perfusion maintenance perfusion for 1 year. Or, epirubicin 30mg is instilled and maintained for 1 year. For tumors of the bladder and ureteral tumors, the same drugs are also needed for bladder perfusion, and the perfusion time is 1 year after maintenance surgery.
