HDQ 200 is an interventional multicenter study. This is a before-and-after design in which the patient is his own control. The main objective of the study is to determine the percentage of success of a procedure of daily hemodialysis at low dialysate flow. All patients treated with conventional hemodialysis, for at least 3 months and clinically stable, can be included in the study. Their 3 months data prior to inclusion is collected retrospectively. These 3 months of conventional hemodialysis are the reference period. Patients are then treated with daily hemodialysis at low dialysate flow for 3 months. During this 3 months period, the same data as during the period of conventional hemodialysis are collected prospectively.

Daily hemodialysis at low dialysate flow during 3 months: 6 times 2h to 2h30 per week at a dialysate flow rate of 200 ml/min in order that the total duration of weekly dialysis is equivalent to the duration of weekly dialysis during the last 3 months of conventional hemodialysis. Other parameters of dialysis (dialysate, dialysis machine, generator, blood flow, anticoagulation) are the same as the reference period of conventional hemodialysis.

Number of patients for whom the period of daily hemodialysis at low dialysate flow will be a success.
Definition of success: if during the period of daily hemodialysis at low dialysate flow, the patient maintains the absolute value of their pre-dialysis serum creatinine (mid-week dialysis) below the upper limit of the confidence interval established during the 3 months prior to inclusion on 7 values: measurements every 2 weeks for 3 months (retrospective data) and inclusion measurement included (Day 0). Daily hemodialysis at low dialysate flow will be considered as a failure if pre-dialysis serum creatinine values exceed twice successively the upper limit of the confidence interval established for the patient.
Time frame: Every 2 weeks during 3 months.
Number of patients who stopped the daily hemodialysis at low dialysate flow (patient or investigator's decision).
Time frame: 3 months.
Number of patients who maintained a satisfactory clinical condition (investigator assessment) during the period of daily hemodialysis at low dialysate flow.
Time frame: 3 months.
Evaluation of weight.
The retrospective study period is 3 months of conventional hemodialysis. The prospective study period is 3 months of daily hemodialysis at low dialysate flow. Detail of time frame during 3 months (retrospectively and prospectively): every 2 weeks.
