Abstract: Hyperuricemia is a serious complication of tumor lysis syndrome (TLS). Uric acid is the end product of purine in the human body. Almost all of the uric acid in the blood is filtered by the glomeruli, and the accumulation of uric acid caused by TLS exceeds the capacity of glomeruli, which results in "hyperuricemia". Excessive uric acid reaches tissues and organs with blood and causes systemic disease. Patients may have symptoms such as nausea, vomiting, joint pain and renal colic. If hyperuricemia causes acute urate nephropathy, severe azotemia and renal failure will occur. In the past, only allopurinol was available for pediatricians to prevent hyperuricemia, while there was no specific drug for the established hyperuricemia. In the last 16 years, Due to the use of uric acid oxidase, pediatricians have become more proficient in the prevention and treatment of hyperuricemia caused by TLS. This review focuses on the hyperuricemia and clinical application of uric acid oxidase.

Key words: tumor lysis syndrome, hyperuricemia, uric acid oxidase
