DMV will Suspend my license for 1 year due to police Errors ?

I have a huge problem. I have a DUI and tht is stressful enough. The problem is the cop who reported that I consented to a urine sample last month and they sent it off for testing has now changed his police report to refusal. Yes I had a drink but now my license might be suspended for a year because he doesn't have a urine sample! What can i do i have the original traffic reprt that states I gave a urine (the DMV would have normally suspended me for under that amount of time) I have a lawyer I havent talked to him yet my arraignment was this morning. They didnt have my paperwork ready. But when they got it ready I was Shocked @ the refusal
