In Mumbai where my mom stays, It costs 1500 Rs per session ( around 25$ per session) now, it used to cost 700 rs couple of years back. My mom doesn't have a travelling issue as the dialysis center is within walking distance of our apartment complex. There are lot of people who travel 2 hours by bus/train everyday to reach her center :( . I really feel for them.
It would be awesome if someone manufactures a portable dialysis machine and / or a artificial kidney . I know there has been some progress but not sure how far is it from actual productization.
