Some gout stones can be dissolved, usually those that have just formed or are relatively small in size. Gout stones are essentially crystals formed by the precipitation of uric acid salts, and the gradual formation of nodule-like changes is called gout stone. When the blood uric acid level in the body is below 360 μmol/L, the urate crystals can gradually dissolve and be excreted from the body in the form of blood uric acid, and the gout stone can gradually become smaller. In order to promote faster dissolution of gout stones, it is recommended to keep the blood uric acid level below 300μmol/L. In contrast, there are larger gout stones and fibrous tissue that have become encapsulated, in which case they are difficult to dissolve and sometimes need to be surgically removed. Once gout stones appear, marking the transformation into chronic gout, which may be combined with kidney damage, patients need to actively control blood uric acid levels to avoid more serious complications.
