  • Glomerular basement membrane abnormalities (too thick or thin) leading to glomerular wall rupture and passage of red blood cell (RBC) into the urinary space, causing tubular obstruction and back leak of glomerular filtrate with resultant parenchymal edema and stretching of renal capsule have been proposed.
