Iv had my bladder removed is there any options for getting a new one put in so i dont have to have a pee bag hanging off my gut?

Depends on details: One might be eligible if there is low risk of cancer recurring, cancer did not affect the urethra, bowels are working well and aren't affected by any other disorders such as Crohn disease, kidneys are working well, and there has not been radiotherapy to the pelvic area.
