[|AI|]  Hello and welcome to Chat Doctor. As a Urologist, I can understand your anxiety. Your father should undergo an plain CT scandium, or a ACTIVE. A 1.8 mm stone is a too tiny, to cause severe pain, as you describe. A ACTIVE is the best single test. It will also show, if the kidney is affected. According to the reports, treatment can be advised. Tell him to Chat Doctor. He may take analgesic, for pain. If you've any doubts, send the reports to me, as a direct question.
