What is the radiographic appearance of uric acid stones on plain X-ray?

The main concept is that what a stone looks like on plain X-ray depends on its mineral content. Calcium-containing stones are radiopaque and show up as bright on X-ray because calcium blocks X-rays. Uric acid stones, however, lack calcium, so they don’t attenuate X-rays well and are radiolucent on plain radiographs. That’s why uric acid stones are typically not visible on standard X-ray films and are better detected with ultrasound or non-contrast CT.
