Surgery usually involves removing your whole bladder. This is called a radical cystectomy.
Cystectomy is used to treat invasive or locally advanced bladder cancer. It may also be used in advanced bladder cancer, when the cancer is only in a small number of lymph nodes close to the bladder.
When your whole bladder is removed, the surgeon will make a new way for you to pass urine. This is called a urinary diversion. It’s done at the same time as the operation to remove your bladder. There are different types of operation to make a urinary diversion.
