Introduction: Emergency hemodialysis (HD) can happen because of numerous factors such as delayed referral to the nephrologist doctor and inadequate care of patient comorbidities. It was challenging because this procedure had a higher mortality than planned hemodialysis. This study aims to present the characteristics of patients who underwent emergency hemodialysis. Methods: A descriptive observational approach was used in this retrospective cross-sectional study of all patients who underwent emergency hemodialysis at Dr. Soetomo General Academic Hospital in January 2023. The inclusion criterion was the availability of complete medical record data indicating the patient’s need for emergency hemodialysis. We collected data on the patient's age, gender, type of renal failure, HD status, comorbidities, and indications of hemodialysis procedure. The data were analyzed descriptively using univariate analysis. Results: A total of 104 patients undergoing emergency hemodialysis were evaluated in this study. The majority of patients were male (50.96%), aged 40–59 years (50%), from Surabaya (51%), and had stage V CKD (88.46%). The most potential causes of declined kidney function were hypertension (65.38%) and diabetes mellitus (37.5%). This study also examined most indications for emergency hemodialysis: hypervolemia (75.96%) and uremia syndrome (68.26%), with 89.42% of patients with multiple indications. Conclusion: The study population was predominantly composed of patients with stage V CKD, most of whom had previously undergone regular hemodialysis. Several patients underwent emergency hemodialysis more than once during January 2023. The majority of patients are in the productive age range and have hypertension and diabetes mellitus. This study also found that hypervolemia and uremic syndrome are the most common indications for emergency hemodialysis.
