I am so sorry the fur baby was injured. As you know the tail contains bones, discs and vertebra.
If any of these were damaged it can take weeks for him to get return of feeling in the area.
Bethanechol is commonly used to get the spinchter to contract.
Onsior may be a viable alternative:
Worst case scenerio is amputation of the tail. We do this if nerve fibers are injured.Or if he is in pain:
Most cats do recover. They do not even miss the tail.
Please let me know how he is doing. I hope he feels better very soon.
