#angionephrography

• Angionephrography — A radiological imaging investigation method consisting of the visualization and structural recording of the renal vascular system (renal arteries and veins) and the renal parenchyma, through the injection of a radiopaque contrast medium. This complex clinical procedure is essential for diagnosing renal artery stenosis (a cause of renovascular hypertension), detecting local circulatory malformations, or evaluating the vascularization of parenchymal tumors.
