Like the calcium phosphate stones, struvite stones are dirty white and radiopaque under an X-ray.

同磷酸钙样，鸟粪是灰白色的，在X线片上是不透光的。

This can combine with ammonium to form struvite stones that often form large staghorn renal calculi, or kidney stones.

沉积下来的物质与铵合形成磷酸铵镁成分的鸟粪，通常形成巨大的角型肾，或普通肾。

This may lead to the formation of urinary stones called struvite, which can cause urine outflow obstruction.

这可能会导致称为鸟粪的尿的形成，从而导致尿液流出阻塞。

It is the 2nd most common cause of UTIs after E.coli, and can also cause formation of struvite urinary stones.

它这是继大肠后次常见的导致尿路感染的病原体，同时也会导致鸟粪尿的形成。

A fourth type are struvite stones, sometimes called infection stones, which are a composite mix of magnesium, ammonium, and phosphate.

第四种类型是鸟粪，也被称作感染性，是镁、铵和磷酸盐的混合物。

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

草酸钙是最常见的类型，其他类型的有尿酸和感染性。

A slightly different type of stone made of the minerals magnesium ammonium phosphate, or struvite, can be caused by bacterial infection.

由矿物质磷酸铵镁或鸟粪制成的类型略有不同，可能是由细感染引起的。

Finally, this leads to urinary stasis, which starts a vicious circle, promoting bacterial multiplication, urinary alkalinization, and the deposition of new layers of struvite.

最终导致尿潴留，尿液的潴留继续促进细增殖，尿液碱化，沉积成新的，形成恶性循坏。
