Kolkata: The number of people receiving treatment for advanced kidney failure such as dialysis or kidney transplant will double to over five million by 2030, mostly in developing regions such as Asia and Africa, a study titled 'Worldwide access to treatment for end-stage kidney disease: a systematic review' said on Saturday.

Renal replacement therapy (RRT), through either dialysis or renal transplantation, is a life-saving yet high-cost treatment for people with end-stage kidney disease.
