Renal dysfunction refers to a variety of situations, including kidney diseases and other diseases, which cause the increase of creatinine and urea nitrogen, accompanied with edema, electrolyte disorder, hypertension and other multiple system related symptoms in some cases. A large proportion of patients were characterized by renal dysfunction as the primary symptom in children. The author summarized the diagnosis approach on childhood renal dysfunction, suggested that the stage on renal function should be based on the same classification standard as in chronic renal disease. Hereditary disease is the most common cause of renal dysfunction in children. Congenital anomalies of the kidney and urinary tract, which might be mainly results from developmental abnormalities, represent a broad spectrum of disorders.

Key words: renal dysfunction, diagnose approach, child
