Conventional versus biocompatible peritoneal dialysis fluids: more questions than answers?

The most important challenge in peritoneal dialysis (PD) is long-term preservation of peritoneal membrane structure and function. Introduction of dialysis fluids into the peri-toneal cavity induces changes. These changes are related to duration of dialysis, occurrence of peritonitis and compo-nents of the dialysis solution. Bioincompatibility is consid-ered to be the major cause of the development of morpho
