Acute Kidney Injury in Upper GI Bleeding Patients
Acute Kidney Injury Following Upper Gastrointestinal Bleeding: Incidence and Predictors
調査の概要
詳細な説明
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.

- Patients with lower gastrointestinal bleeding
- Patients with incomplete or missing essential renal function data
- Patients discharged or deceased within 24 hours of hospital admission
- Pregnant patients
- Patients with acute kidney injury at presentation due to causes other than UGIB

Patients with Acute Upper Gastrointestinal Bleeding
Adult patients (≥18 years) presenting with acute upper gastrointestinal bleeding (UGIB) and admitted to Sohag University Hospitals.
Patients will be followed prospectively to assess the incidence of acute kidney injury (AKI) and its predictors.
|
No therapeutic intervention is applied.
Patients are managed according to standard hospital care, and data are collected observationally.
