Focal segmental glomerulosclerosis (FSGS) without nephrotic syndrome

Focal segmental glomerulosclerosis without nephrotic syndrome describes a clinicopathologic presentation of glomerular disease characterized by histopathological scarring affecting portions of some, but not all, renal glomeruli Pathophysiologically, this presentation typically reflects podocyte injury or detachment driven by secondary etiologies—such as hemodynamic maladaptation, hyperfiltration from reduced nephron mass, obesity, viral infections, or genetic podocytopathies—rather than circulat...

Unlike classic primary presentations, affected pediatric and adult patients do not exhibit the complete nephrotic tetrad, manifesting instead with subnephrotic or asymptomatic proteinuria without severe hypoalbuminemia or generalized edema Pathophysiologically, this presentation typically reflects podocyte injury or detachment driven by secondary etiologies—such as hemodynamic maladaptation, hyperfiltration from reduced nephron mass, obesity, viral infections, or genetic podocytopathies—rather t...
