Which is the target Kt/V per HD session?

• A. Around 1.2
• B. Around 0.8
• C. Around 2.0
• D. Around 1.0

Answer: (A)

Kt/V per hemodialysis session is the amount of urea cleared during one treatment relative to the patient’s total body water, i.e., the dose delivered in that session. For standard thrice-weekly HD, a per-session target around 1.2 strikes the balance between adequate solute removal and avoiding excessive treatment time or hemodynamic stress. Values notably lower, like 0.8 or 1.0, suggest undertreatment and are associated with worse outcomes. A per-session target around 2.0 would indicate a much heavier dose than typical practice and isn’t routinely pursued, as it can increase intradialytic complications without proportional benefit. Thus, around 1.2 per session is the conventional goal to ensure sufficient overall dialysis exposure across the week.
