These stones, also like uric acid stones, are red-brown in color and radiolucent under an X-ray.

这类结石也像尿酸结石一样，呈红棕色，X射线可透过。

The most common type of stones are calcium oxalate stones, though other types include uric acid stones and struvite stones.

草酸钙结石是最常见的类型，其他类型的结石有尿酸结石和感染性结石。

There are also uric acid stones which are red-brown in color and radiolucent under an Xray, meaning that they're transparent to x-rays and don't show up very well.

另外还有呈红棕色的尿酸结石，在X光片上不显影，说明X射线可以穿过它们，不能很好地显影。

At a physiologic pH, uric acid loses a proton and becomes a urate ion, which then binds sodium, forming monosodium urate which crystallizes and ultimately forms uric acid stones.

生理PH值下，尿酸失去一个质子变成尿酸盐离子，随之与钠结合，形成单钠尿酸盐，结晶后最终形成尿酸结石。
