=== Artificial kidneys ===
They exist already, for a long time.
''"If you have both kidneys completely removed, you will not make any urine. You will need to have kidney dialysis <...> many people manage very well with it. There are 2 different types of kidney dialysis. You can use a kidney dialysis machine at a dialysis centre. Or you can use a permanent tube and bag of fluid at home"''[https://www.cancerresearchuk.org/about-cancer/kidney-cancer/living-with/daily-life]<br/>
Good visualisation of dialysis: https://www.youtube.com/watch?v=gRoleVEwR8c&t=58s (from 0:58 to 1:52) <br/>
See [[Patients survival on dyalisis]]; briefly, it's 5-10 years, with cachexia and infections as specific causes of death.

Dialysis rate is "usually between 300 and 500 mL/min"[https://www.davita.com/treatment-services/dialysis/on-dialysis/how-does-my-doctor-know-if-dialysis-is-working]. <br/>
Compare to total cerebral blood flow which is roughly 700±100 mL/min[https://www.ncbi.nlm.nih.gov/books/NBK538134/#:~:text=Blood%20flow%20distribution%3A,%C2%B1123%20mL%2Fmin).]. <br/>
Annual dialysis cost (usually with 3 sessions a week for 3-6h each) is roughly $3400 to $43000 depending on country[https://pubmed.ncbi.nlm.nih.gov/26563300/] (1998-2013 studies were reviewed; year was different for countries). Anyway it's probably a small part of overall costs for head transplantation.<br/>

"Over 2 million people worldwide currently receive treatment with dialysis or a kidney transplant to stay alive, yet this number may only represent 10% of people who actually need treatment to live"[https://www.kidney.org/kidneydisease/global-facts-about-kidney-disease] so really large interested community, large market etc.
