An arteriovenous fistula or graft is essential for hemodialysis (HD). It involves connecting a high-resistance artery to low-resistance vein, which increases cardiac output (CO). In the early days of HD, patients with end-stage kidney disease (ESKD) were typically younger, and their HD access was located in distal forearm. However, modern era, ESKD are often elderly, many being very elderly (over 80 years old). These have poor vessel quality, making forearm unsuitable. As result, upper arm...
Abstract Background The revised 2023 guidelines from the International Society for Peritoneal Dialysis (ISPD) emphasize salvage methods treating refractory catheter-related infections, or mechanical catheter damage. This approach preserves existing by manipulating only outer cuff above peritoneum, avoiding hemodialysis transfer. We investigated effectiveness of partial replantation technique. Methods In this retrospective single-center study (January 2021 - December 2023), outcomes nine...

High baseline anti-ABO antibody titer is still an important obstacle for successful ABO-incompatible kidney transplantation (ABO IKT). This study aims to investigate the clinical outcome of ABO IKT in patients with a high comparison low titer. Fourteen who received at our center were classified as high-titer group (≥1:256, n = 8) or low-titer (≤1:128, 6). We used protocol composed rituximab, plasmapheresis, and intravenous immunoglobulin (RTX/PP/IVIG). compared intensity preparation,...
Osmotic demyelination syndrome (ODS) primarily occurs after rapid correction of severe hyponatremia. There are no proven effective therapies for ODS, but we describe the first case showing successful treatment central pontine myelinolysis (CPM) by plasma exchange, which occurred development hypernatremia from intravenous sodium bicarbonate therapy. A 40-year-old woman presented with general weakness, hypokalemia, and metabolic acidosis. The patient was treated oral potassium chloride, along...
