What is the likelihood of this poor kitty regaining bladder/bowel function?

We recently trapped and rescued an injured stray. We’ll never fully know what happened to him but he has a multitude of injuries some old and healed and some not. Required a lot of teeth to be pulled and had to have his tail amputated due to sores and maggots inside. He has about 2 inches of tail left. Surgery was done 3 days ago. He wasnt moving his tail when we got him but is walking fine. Since getting him home I notice hes leaking urine with no control and seems to be constipated. I’m unfortunately no stranger to spinal injuries in cats but he appears to still have anal tone, unsure about sensation at tail base and is mobilising fine. But his abdomen seems quite distended and a little tense. I have managed to express urine from him and giving him laxatives (back to the vets tomorrow if no poops). Just wondering what his outlook is likely to be to better guide his rehab. I know it might be too soon to tell yet but any guidance is appreciated.
