Ultrafiltration and Small Solute Transport at Initiation of PD: Questioning the Paradigm of Peritoneal Function

Abstract

The functional characteristics of human peritoneum varied markedly and there was a less intense than expected relationship between solute and water transports. This mild inverse relationship is intriguing and suggestive of the necessity of redefining some basic concepts. Age was associated with a lower peritoneal UF capacity, in part independently of small solute transport.
