Renal Stem Cells, Renal Resistive Index, and Neutrophil Gelatinase Associated Lipocalin Changes After Revascularization in Patients With Renovascular Hypertension and Ischemic Nephropathy.

Although limited to a few patients, our observation allowed the exploration of the behaviour of the studied parameters in different degrees of renal ischemia. This revealed different disease models suggesting the importance of further investigations in larger and homogeneous cohorts to confirm that a greater basal RSC percentage, low RRI values before PTRA, and a post-revascularization NGAL reduction could be related to better renal outcomes in aRAS patients.
