In 90-95 % of cases, urothelial cancer primarily affects the bladder and in about 5-49 % of patients it can be located near or completely close the orifice of the ureter. Metachronous urothelial cancer of the upper urinary tract occurs, as a rule, 3 or more years after transurethral resection of the primary bladder tumor or radical cystectomy, and its frequency with involvement of the ureteral orifice ranges from 0 to 20 %, reaching 51 %. Currently, there are no clear recommendations and diagnostic and treatment algorithm for the management of this category of patients. This review examines the frequency, possible causes and risk factors for recurrence of upper urinary tract tumors, indications for organ-preserving treatment, features of surgical technique for transurethral resection of ureteral orifice tumors, emerging complications and methods of their prevention.
