Electron microscopy: one non-obsolescent glomerulus was subjected to ultrastructural examination, with good tissue preservation. Podocytes display widespread effacement of foot processes, which correlates to proteinuria. Glomerular basement membranes are uniformly contoured except for a few segments with mild corrugation (mean glomerular basement membranes thickness, 303 ± 48 nm). Electron dense deposits were not seen
