I found some information about artificial transplant at http://www.kidney.bc.ca/kidneys/transplants/index.html and brought it over to Mt. Temasek Specialist Centre. Dr Leevur confirmed with me that the information I found was correct.

Pros:
1. Reduced risk of rejection due to the absence of antigens production in artificial organs
2. No need for donor, reduced time for waiting
3. Patient’s pain eased
4. No need for dialysis
5. Diet and fluid restriction gone
6. Normal lifestyle returned

Cons:
1. Finite life span of implants due to wear and tear
2. Need to be replaced after a certain time
3. Costly
4. Hip or knee replacement surgery must undergo surgical revision within three years
5. Constant revision
6. Unnatural
7. Emotionally unease for some people
8. Medication might be necessary

Grandma is currently relying on dialysis, we need to make a decision soon. Weighing the pros and cons, there seems to be more cons than pros, but this is our only hope!

Its really troublesome to go for dialysis 3 times a week all the way to MTSC, and given grandma's fragile state it's really worrying for us and dialysis is really not a long-term solution. Anyhow, heres a picture of how dialysis works from http://www.ivy-rose.co.uk/Topics/Urinary/Kidney_Dialysis_cIvyRose.jpg for all you people out there who are not sure how it works!
