There are 1.8 million new cases of the most serious form of kidney disease – renal failure – each year. Unless patients with renal failure receive a kidney transplant or undergo dialysis – an expensive life-long procedure that cleanses the blood of toxins – death is guaranteed within a few weeks.
最严重的肾脏疾病—肾衰竭—每年会新增180万例。除非肾衰竭患者接受肾移植或是进行透析（这种程序可以清楚血液内的毒素，但是价格昂贵，还要持续终生），几周之内就会死亡。
