     View Summary

    Hypertension, aging, and other factors are associated with arteriosclerosis and arteriolosclerosis, primary morphologicalfeatures of nephrosclerosis. Although such pathological changes are not invariably linked with renal decline but areprevalent across chronic kidney disease (CKD), understanding kidney damage progression is more pragmatic than preciselydiagnosing nephrosclerosis itself. Hyalinosis and medial thickening of the afferent arteriole, along with intimal thickening ofsmall arteries, can disrupt the autoregulatory system, jeopardizing glomerular perfusion pressure given systemic bloodpressure (BP) fluctuations. Consequently, such vascular lesions cause glomerular damage by inducing glomerularhypertension and ischemia at the single nephron level. Thus, the interaction between systemic BP and afferent arteriolopathymarkedly influences BP-dependent renal damage progression in nephrosclerosis. Both dilated and narrowed types of afferentarteriolopathy coexist throughout the kidney, with varying proportions among patients. Therefore, optimizingantihypertensive therapy to target either glomerular hypertension or ischemia is imperative. In recent years, clinical trialshave indicated that combining renin–angiotensin system inhibitors (RASis) and sodium–glucose transporter 2 inhibitors(SGLT2is) is superior to using RASis alone in slowing renal function decline, despite comparable reductions in albuminuria.The superior efficacy of SGLT2is may arise from their beneficial effects on both glomerular hypertension and renalischemia. A comprehensive understanding of the interaction between systemic BP and heterogeneous afferent arteriolopathyis pivotal for optimizing therapy and mitigating renal decline in patients with CKD of any etiology. Therefore, in thiscomprehensive review, we explore the role of afferent arteriolopathy in BP-dependent renal damage.
