Peritoneal dialysis (PD) is currently used on
15% of the worldwide dialysis population. Recent improvements in connectology and antibiotics management have led to a dramatic reduction in the rate and consequences of peritonitis in PD patients. Deterioration of membrane permeability, with modifications in the transport of small solutes across the peritoneal membrane (PM) and loss of ultrafiltration (UF), is the most frequent abnormality in long-term PD patients, and the main reason for technical failure. A better understanding of the mechanisms and determinants of the small solute transport and UF is now essential to achieve long-term preservation of the PM together with improvements in patient morbidity and mortality.
The transport of solutes and water across the PM occurs through three types of pores located in the capillary endothelium [1]. The small pores (radius 4050 Å), which correspond to the clefts located between endothelial cells, account for
