Sensitivity and Specificity of Color Doppler Ultrasound Measurement in the Evaluation of Renal Artery Stenosis

Abstract

Renal artery stenosis typically results from plaque development. Mostly frequent cause of severe hypertension is RAS, which affects 1% to 5% of all patients with hypertension. Objective: To assess the sensitivity and specificity of Doppler ultrasound in RAS. Methods: Data from several search engines were retrieved for this literature view. Research was evaluated for both its quality and its usefulness. Data extraction from the whole journal articles was done. Results: Only 20 articles were used for extraction of data related to Sensitivity and Specificity of color Doppler ultrasound measurement in evaluation of RAS. The current study looked at the assessment of RAS. Conclusions: From assessing stenosis of renal artery diameter to analyzing the enhanced velocity field at the obstruction site, identifying new measures to describe plaque susceptibility in the renal artery has become more significant.
