I'm not sure why he won't even look at the scan if not just to appease you. Ask him to again. However, the ER just wanted to give you direction. They got you to the urologist. They are NOT urologists and this person is. I'm all for the least invasive method of doing anything so I get your concern. But this is this doctor's specialty. You 'could' get a second opinion. An ER is not going to be anywhere near level of expertise as a urologist as they spend all day seeing patients with similar issues to you. Bladder stones can lead to an enlarged prostate so that makes sense. Here are treatment options for kidney stones and remember, you have six of them based on the urologists testing. https://www.niddk.nih.gov/health-information/urologic-diseases/kidney-stones/treatment To be honest, the urologists plan to remove the stones sounds reasonable.
