The purpose of this study is to evaluate whether a personalized, high-rate fluid removal strategy guided by ultrasound is as safe and effective as the standard fluid removal rate for patients with advanced kidney disease who are hospitalized due to severe fluid overload (congestion). When patients with End-Stage Renal Disease (ESRD) on chronic hemodialysis are admitted to the hospital with excess fluid, doctors often need to remove this fluid quickly to relieve symptoms like severe shortness of breath. However, traditional guidelines recommend conservative fluid removal rates-called ultrafiltration (UF) rates-between 10 and 13 mL/kg/h to prevent sudden drops in blood pressure (intradialytic hypotension). Despite these guidelines, doctors in real-world hospital settings frequently use higher rates to provide urgent relief, though this practice lacks strong scientific backing. This study utilizes advanced bedside ultrasound protocols (such as lung ultrasound and VExUS) to objectively measure the amount of fluid congestion inside the patient's blood vessels. The researchers hypothesize that patients with high ultrasound markers of congestion can safely tolerate higher fluid removal rates because their blood vessels are overfilled, meaning fluid can be pulled out faster without causing blood pressure drops. Participants will be randomly assigned to one of two groups during their first in-hospital hemodyalisis session: * Standard Group: Receives a standard fluid removal rate of 10 mL/kg/h. * High-Rate Group: Receives a higher fluid removal rate of over 13 mL/kg/h (with a safety ceiling up to 15 mL/kg/h). The study will compare the two groups over the first 24 hours to monitor blood pressure stability (safety) and check for improvements in ultrasound congestion scores, shortness of breath, and the need for supplemental oxygen (effectiveness).

Safety (Incidence of Intradialytic Hypotension - IDH)
Timeframe: During the interventional hemodialysis session.
Ultrasound Efficacy
Timeframe: Comparison between Baseline (pre-intervention) and within 24 hours post-intervention.
Clinical Respiratory Efficacy
Timeframe: The patient's condition is assessed before starting the therapy, and their clinical progress is evaluated within the 24 hours post-intervention.
