Answer

Edema is present in 80-90% of cases, and it is the presenting complaint in 60% of cases. Compromised intraglomerular blood flow due to glomerular hypercellularity results in progressive encroachment on the cross-sectional area of the glomerular capillaries. This leads to reduced blood flow that manifests as low fractional excretion of sodium and concentrated urine. This salt and water retention leads to edema.
