简要总结
Every patient included in the study will undergo 1 conventional hemodialysis treatment, ie 1 study visit. During the conventional hemodialysis treatment lasting 4 hours, 2 blood samples will be taken at different time points (5 minutes after dialysis start and 240 minutes after dialysis = at the end of the dialysis session) to evaluate coagulation activation (TAT, PF1+2). Hemodialysis session parameters (arterial and venous pressure, TMP, OCM, BVM and prefilter pressure) will be noted at different time points (T5, T30, T60, T120, T180, T240). After discontinuation of the dialysis session, total cell volume will be measured using the Renatron II system® and the number of open fibers will be determined using micro-CT scanning.

结局指标
主要结局
open fibers
时间窗: From first hemodialysis study session until interpretation of scan results, up to 6 months
number of open fibers of dialyzer counted after microCT scanning of dialyzer membrane. Dialyzers were collected after the hemodialysis study treatment. All patients underwent their study treatments between October - December 2018. All micro CT scans were performed using the same scanner in Fabruary and March 2019.
TAT
时间窗: From first hemodialysis study session until interpretation of biological results, up to 6 months
thrombin antithrombin complex levels (mcg/L). Samples for TAT measurement were taken during the single hemodialysis study treatment. All patients underwent their study treatments between October - December 2018. All analyses were performed in batch in January 2019.
