How long does alcohol stay in urine?

Okay, so, I have to meet with my probation officer tomorrow the 7th , and I drank on Saturday night which was the 3rd. I had a whole pint of vodka. I just want to know typically how long alcohol stays in urine for it to show up on a ETG test? I don’t even drink heavy. I’ve been sober for 9 months but I slipped up the other night honestly and I’m a little anxious about meeting with my PO tomorrow. I’ve heard it stays in your system for 48 hours from some sources and I’ve heard it stays in your system for 80 hours from some sources but some people say that the 80 hours is just a scare tactic that law enforcement uses to keep you from drinking. Someone please put my mind at ease LOL I appreciate it thank you very much ..
