Tophi deposit in the peripheral bone joints or soft tissues are formed by uric acid and urate crystal. It does not only affect local appearance but also destroy the bone and joint structure, resulting in loss of function. Traditional medical treatment is an effective way to control the hyperuricemia, but it is ineffective to tophus. Surgery is a relatively effective method for the treatment of tophus. It can successfully reduces the content of uric acid in the body and improves the limbs function, but it causes surgical trauma and complications. As new medicine, Urcase is a hot spot in the present study. It can not only control the blood uric acid level but also dissolve part of tophus. But the cost is higher than traditional medicines. There is still dispute in treatment for advanced tophus.
