Sadly most of those conditions are "Greek" to me but I do get the point you are making.I have no idea. I work for neurosurgery so I know more about my department.
I would assume a transplant is urgent due to the organ only being good for a certain amount of time but my hospital doesn’t do organ transplants.
Pain doesn’t equal urgency. If you need a spinal fusion due to radiculopathy most of those are waiting. If you need it due to cervical myelopathy and are at risk of being paralyzed those are being done. Brain tumor are being done.
