Suggest Remedy For Disability In Bottom Half Of Body Due To Injury

Dear Sir
One of my cousin fell from building (Age 37, Male)
At that time his back has damaged and all the spinal discs disturbed, then he got operated and all the discs relocated and support with two screws. Now he is able to sit in wheel chair, but he bottom half of body has no sense.
He does not have sense to go for urine and not able to lift his legs and he is always laying on the bed.
Doctor has told us that his main nerve has cut at the bottom and he will get back to his normal life any more

We have following quires
1. Is there anything can be done to him to get normal things?
2. can you suggest any hospital and doctor to consult for any further treatment
