Some renal insufficiency caused by high uric acid can be cured. Renal insufficiency refers to the clinical syndrome characterized by water, electrolyte, acid-base balance disorder and systemic symptoms caused by the decrease of glomerular filtration rate and retention of metabolites due to various reasons. The patients may show fatigue, decreased urine output, edema, nausea, decreased appetite, high blood pressure, dyspnea, skin itching and other symptoms. Etiological treatment and active prevention and treatment of complications can delay or reverse the progress of renal insufficiency. The most effective treatment for renal insufficiency is early diagnosis and treatment of the primary disease to avoid and correct the risk factors of renal insufficiency. If there are complications, active treatment is needed, and renal replacement therapy should be carried out in time for the severe cases.
