Summary

The goal of this clinical trial is to estimate the accuracy of renal resistive index in early diagnosis and prediction of acute kidney injury in patients with hemorrhagic stroke. the main questions it aims to answer are : * Early detection of acute kidney injury in patient with hemorrhagic stroke . * Decrease morbidity and mortality rate in patients with hemorrhagic stroke .

Conditions

• Early Diagnosis of Acute Kidney Injury

Interventions

Type	Name	Description
DEVICE	Ultrasonographic examination and doppler ultrasonography will be performed using a convex transducer.	-Renal Resistive Index Measurement Method: Ultrasonographic examination and doppler ultrasonography will be performed using a convex transducer. First, the kidney is localised in the flanks with conventional B-mode ultrasonography, after which, color doppler images are acquired. The interlobar arteries were visualised, with the wavelength obtained by creating a 90-degree right-angle with the interlobar artery using a power doppler. After the manual determination of the peak systolic and end-diastolic velocities \* RRI will be calculated by the device using the formula: RRI = (peak systolic velocity - end-diastolic velocity) / (peak systolic velocity). RRI will be measured three times for each kidney and averaged
