Why use the intrusive and debilitating hemodialysis at all when peritoneal dialysis shows a 48% improved mortality rate, as noted by the NIH here
I know. I've done both.
It looks like the United States does not allow Hemodiafiltration outside of ICUs, so you may not have had this therapy, at all:
Online Hemodiafiltration
Hemodiafiltration (HDF) combines both hemofiltration (HF) and HD in a single procedure. Whereas in the United States HDF is mostly performed in intensive care units, many other countries have adapted this modality for outpatient therapy, mostly known as “online” HDF. Online HDF, where replacement fluid is prepared from ultrapure dialysate, can be performed safely thanks to recent technologic advances; however, in some countries, including the United States, government restrictions prohibit the use of online HDF.
