[/INST] Hello Welcome to Chat Doctor. Thanks for posting your query. And its superb that you have given all the details required. With young guys, 5 mm calculus in kidney there's nothing to worry. This is point number 1. So, do not worry. I've seen huge calculus than this. Does this cause severe pain? If occasional tolerable pain then neglect it.  Chat Doctor.  And if its troubling you with pain then take tablet attract for time being. There is absolutely no indication for surgery or any intervention for 5 mm stone. But having said that, do keep a track on that stone. Sometimes it may pass off by its own. Or else, it may grow large. Then probably you'll need something called ESL. So as of now do not worry. Be calm and do as I advised. And coming to the second query, diet. There are so many papers published regarding this but there's no standard protocol. Avoid 1. Junk food. 2. High intake of salt 3. Cut down on meat. Hope this helps, and you can contact me anytime regarding this. </s>
