Fetal Week 20 as the Mechanical Turning Point of Retroperitoneal Fascial Lamination: A Poisson-Effect Framework

2026-03-25

Abstract excerpt

This study presents a theoretical mechanobiological model explaining the multilaminated architecture of retroperitoneal fasciae. Classical peritoneal fusion theories cannot account for either these organized laminae or the 10‑week delay between early visceral fixation and definitive fascial formation. We propose that early localized tension at 10–12 gestational weeks forms the inner renal fascial layer, whereas a...
