Synopsis

Focal segmental glomerulosclerosis : Microscopic hematuria, Proteinuria, Peripheral leg edema, Generalized edema, Weight gain, BP increased
Focal segmental glomerulosclerosis (FSGS) is a histologic description of a glomerular lesion that is associated with significant proteinuria and the nephrotic syndrome. This pathologic finding can be the result of systemic disorders (termed "secondary" causes of FSGS) or may represent primary disease.

Primary FSGS is itself a heterogeneous disease, likely with multiple pathogenic mechanisms resulting in a similar histologic pattern of injury. Secondary causes include chronic reflux nephropathy, chronic hypertension, and obesity.

Clinical presentations vary widely, but typically individuals with primary FSGS present with the nephrotic syndrome. Secondary FSGS is typically associated with less severe proteinuria, often without hypoalbuminemia or peripheral edema. Patients may require renal transplantation, which may have a high frequency of failure from recurrence of FSGS.
