Accuracy of Venous Excess Ultrasound Score at Hospital Admission to Predict Acute Kidney Injury

This study is testing whether a special ultrasound scoring method — called the Venous Excess Ultrasound (VExUS) score — can predict which pregnant women with severe preeclampsia (a dangerous high blood pressure condition in pregnancy) will develop kidney injury during their hospital stay. The ultrasound looks at blood flow patterns in veins to detect signs of fluid overload. **You may be eligible if...** - You are pregnant and have been diagnosed with severe preeclampsia **You may NOT be eligible if...** - You have already had kidney problems before this pregnancy (creatinine above 1.3 mg/dL) - The ultrasound images cannot be clearly obtained - You have had a kidney transplant - You have previously required dialysis or kidney replacement therapy - You have known peripheral vascular disease - You decline to participate Talk to your doctor to see if this trial is right for you.
