There are two reasons for the increase of blood uric acid after kidney transplantation: one is the long-term use of immunosuppressants, abnormal uric acid metabolism leading to hyperuricemia; the other is the abnormal function of the transplanted kidney, impaired uric acid excretion and increased blood uric acid. If the blood uric acid is mildly increased and there is no gout attack, no treatment can be suspended. If gout attack occurs, the first thing is to control joint inflammation (colchicine and other antipyretic and analgesic drugs can be taken), the second thing is to inhibit uric acid production, allopurinol tablets can be taken; in addition, the normal kidney function can also be taken to increase the excretion of blood uric acid, such as Ligarixian.
