Removal of Uremic Toxins With Nocturnal Dialysis Versus Standard Dialysis

Dialysis patients, who decide to switch from standard dialysis (3 times 240-270 min/week) to nocturnal dialysis (3 times 480 min/week), will be followed. In parallel a control group with patients staying on standard dialysis will be followed. The study will last 30 weeks. During this period blood samples (pre- and post-dialysis: 10 times; inlet and outlet of dialyzer: 3 times) will be collected on predetermined time points. Concentration of several uremic retention solutes will be determined.
