What causes sponge kidney?

Sponge kidney is a pathological change of kidney, often easy to form stones, and this stone is relatively difficult to cure. Because the stone repeatedly grows, the effect of its operation is not so good. At this time, we should try to prevent it from forming stones and pay attention to protecting kidney function. This stone is relatively difficult to cure, because stones are not easy to break and not easy to clean. This condition is not particularly common clinically, but if it occurs, it can only be followed up regularly to prevent the formation of stones and protect kidney function. However, its overall effect may not be particularly good, so it is necessary to visit the doctor regularly.
