Focal, segmental glomerulosclerosis (FSGS)

FSGS is a progressiv glomerular kidney disease that is characterized by scars that form focally, only some glomeruli altered, and segmentally, only parts of the glomerulus affected.

Clinical Findings

Proteinuria, glomerular haematuria, and progressive decline of renal function are the dominating clinical symptoms, which start in teenage years and may develop to end-stage renal disease in some individuals.
