终末期肾功能衰竭的重要并发症之一就是钙磷代谢紊乱。高磷血症是影响维持性血液透析患者生存质量和增加病死率的危险因素。血磷升高可诱发甲状旁腺功能亢进,从而导致肾性骨病的发生及皮肤瘙痒、高脂血症、神经传导速度减慢等。最近研究认为,血磷及钙磷乘积升高是引起终末期肾 One of the most important complications of end-stage renal failure is dysfunction of calcium and phosphorus metabolism. Hyperphosphatemia is a risk factor affecting the quality of life and increasing mortality in maintenance hemodialysis patients. Increased blood phosphorus can induce hyperparathyroidism, resulting in the occurrence of renal osteodystrophy and skin itching, hyperlipidemia, nerve conduction slow down. Recent studies suggest that the increase in blood phosphorus and calcium phosphorus is caused by end-stage renal
