ABSTRACT Invasive bladder cancer is a cancer that is becoming increasingly common among men. Radical cystectomy is widely used as the primary treatment for this type of tumor. In order to improve the quality of life of patients, which is no less important than the survival rate, specialists in modern practical oncology have introduced more than 46 types of urine diversion into practice in the period after such highly traumatic operations. Complications after these operations and the problem of their elimination also remain relevant.
