Question about court...?

I have been on probation for three years. I just got my discharge papers saying I'm off probation. I also recieved a paper saying I have a court hearing for restitution. I have been paying on my fines for a long time. I'm just wondering what's goig to happen at this hearing?? Is it just to put me on a payment plan, or will they put me back on probation?? Also, do you think thy will give me a urine ysis when I go to court?? ((yes I'm clean, I just need to know if I should use the bathroom or not before court))
