简要总结
This study aims to evaluate the incidence of acute kidney injury (AKI) among patients presenting with acute upper gastrointestinal bleeding (UGIB) at Sohag University Hospitals, and to identify predictors associated with renal impairment in these patients.
详细描述
Upper gastrointestinal bleeding (UGIB) is a common medical emergency associated with significant morbidity and mortality. Acute kidney injury (AKI) is frequently observed in these patients, mainly due to hypovolemia and renal hypoperfusion. Despite its clinical importance, data regarding AKI incidence and predictors in UGIB patients, particularly in Middle Eastern populations, remain limited.
This prospective observational study aims to assess renal function abnormalities and identify predictors of AKI in patients with UGIB, including both variceal and non-variceal causes. The study will also evaluate clinical outcomes such as mortality, hospital stay duration, and need for renal replacement therapy.
