Estimate single-pool Kt/V (spKt/V) for a hemodialysis session with the Daugirdas second-generation formula: Kt/V = −ln(R − 0.008·t) + (4 − 3.5·R) × UF / W, where R = Post-BUN/Pre-BUN, t = treatment time (h), UF = ultrafiltration volume (kg), W = post-dialysis weight (kg). The first term captures urea removal and generation; the second corrects for volume contraction. KDOQI target: spKt/V ≥1.2 per session (minimum delivered dose) for conventional thrice-weekly hemodialysis, target ~1.4. Requires post-dialysis BUN drawn by slow-flow/stop-pump technique. Derived from Daugirdas JT, J Am Soc Nephrol 1993. Valid for intermittent hemodialysis; not for peritoneal dialysis or CRRT/SLED. Not medical advice.
