This study evaluated 30 patients who received urgent hemodialysis sessions at a single center over 14 days. The patients presented with indications including pulmonary edema, hyperkalemia, and uremic encephalopathy. Preliminary diagnoses included acute kidney injury (AKI), AKI on chronic kidney disease (CKD), end-stage renal disease (ESRD), and ESRD on hemodialysis. Final diagnoses for some patients changed. The majority received multiple hemodialysis sessions, with outcomes being improvement in 5 patients and ongoing dialysis in 23 patients. The study recommends pre-dialysis care for CKD patients and early hemodialysis initiation for AKI to avoid life-threatening complications.
