Background and Aim: What constitutes adequate dialysis has been debated in the nephrology literature over the past years. We believed that short and infrequent dialysis session contributed to poor outcome. This result provides additional evidence that (KT/V) in a flawed concept upon which to based the dose dialysis in general. Base on published evidence from many source we proposed a new index of adequacy of hemodialysis to be called hemodialysis product (HDP).

Materials and Methods: The prospective study was performed on 100 dialysis patient in the Imam hospital dialysis ward in Tehran during 2002. delivered (KT/V) and (HDP) achieved for any patient separated. Results: 100 patients including 44 female and 56 male were studied. Result has shown (KT/V) d≥ 1 in 43% and (KT/V) d< 1 in 57%. HDP in patient with (KT/V) d > 1 were ≥ 36. HDP in patient with (KT/V) d < 1 were < 36. Correlation between (KT/V) d and albumin was significant (p< 0.03, Albumin ≥ 4 mg/dl). Correlation between (KT/V) d and cholesterol, hemoglobin, creatinine were not significant. Correlation between (KT/V) d and HDP was significant (p< 0.001).

Conclusion: Finding above has shown that higher weekly delivered (KT/V) correlate with dialysis result increase hemodialysis product (HDP). More frequent and session dialysis results increase in HDP, provide better weekly (KT/V) d with normal albumin (show good caloric and protein intake).
