[2025-10-01T15:17:19.787802] [PI reasoning] **Exploring radiolucent stones**

I need to determine which stones are radiolucent. Uric acid and xanthine are typically radiolucent, while cystine stones can be tricky since they are mostly radiolucent but may show faint opacity due to sulfur. There’s some confusion about how allopurinol fits in here since it can cause xanthine accumulation, and there’s also orotic acid to consider. I’ll need to do a quick search to clarify these classifications.
