Abstract The fundamental objective of dialysis is to maintain the dose of solute clearance and ultrafiltration (UF). When peritoneal dialysis (PD) patients cannot maintain target clearances, the dialysis dose needs to be increased. The means of increasing dose by PD alone are limited, especially in patients with UF failure. Combination therapy with PD and hemodialysis (PD+HD) is the simplest way to solve this problem. The general prescription for PD+HD should be 5-6 days of PD and 1 session of HD weekly. To determine the adequacy of PD+HD, we adopted the equivalent renal clearance (EKR), transforming the weekly Kt/V from PD and then evaluating the total clearance from both modalities. The weekly PD+HD regimen improves clinical status in patients in whom PD alone does not result in dialysis adequacy, and it permits a substantial prolongation of PD. The complementary effects of PD and HD improve clinical status and prognosis in patients undergoing dialysis; we therefore propose to use the term "complementary dialysis" for this technique.
