Does anyone know why doctors cannot use human 'donors' for bladder transplants? See link?

Answer 1

Possible because the bladder is inervated by the spinal nerves,
and if you transplanted one you might not get the control you had previously. When they remove a bladder because of cancer, they perform an ureterostomy, this is a cleaner way to deal with urine, rather than being incontinent.So I would think that if incontinence were the issue and you transplanted a bladder and didn't have the same control as you did, or the same control it would be pointless--
it's a complicated little organ.
