The outcomes of iUSPD were compared with other extracorporeal dialysis in MALA. Methods In two tertiary hospitals in Thailand, the outcomes of patients with MALA who had received three different RRT modalities (iUSPD followed by IHD, IHD, and continuous renal replacement therapy [CRRT]) from January 2015 to December 2019 were compared.
