Renal pathology theory classifies congenital anomalies based on embryological development failures and genetic mutations affecting nephron structure, distinguishing between life-compatible unilateral agenesis which triggers a Potter sequence due to oligohydramnios, and fatal bilateral agenesis. Nephrotic syndrome is defined as a clinical state resulting from glomerular barrier dysfunction causing proteinuria >3.5g/day, hypoalbuminemia, hyperlipidemia, edema, and thrombotic risk via the loss of antithrombin III; specific etiologies include Minimal Change Disease (podocyte foot process effacement), Focal Segmental Glomerulosclerosis (segmental sclerosis due to mutations or HIV/collapse variants), and Membranous Nephropathy characterized by subepithelial immune complex spikes.
