# Hypertensive Nephropathy: Attribution Is a Diagnosis to Test

Distinguish an administrative diagnosis from proven causation. A credible explanation should fit the timeline, phenotype, and available pathology.

## Pressure and injury interact

Hypertension can damage kidneys, and kidney disease can raise blood pressure. This bidirectional relationship complicates claims about which came first.

## Recognize attribution risk

A patient with hypertension and CKD does not automatically have primary hypertensive nephropathy. Other glomerular, vascular, genetic, and systemic causes may be present.

## Reconsider when the phenotype does not fit

Heavy proteinuria, active sediment, abrupt decline, a strong family history, or extrarenal findings should prompt consideration of glomerular, genetic, vascular, or systemic disease. Longstanding hypertension may be a consequence or amplifier rather than the sole original cause.

## Assess protection and failure

Renal autoregulation, vascular disease, nephron loss, and inherited susceptibility influence how systemic pressure translates into glomerular injury.

## Treat risk while investigating

Appropriate blood pressure and kidney-protective care remain valuable even when the etiologic label is uncertain.

## Choose testing for the unresolved question

Ask whether biopsy or genetic evaluation would alter treatment, prognosis, or family counseling. Do not infer a genetic mechanism from race alone. Record why hypertensive nephropathy is plausible, what alternatives were assessed, and which future change would reopen the diagnosis.
