Focal glomerulosclerosis clinical classification

FSGS can be idiopathic, can also be common for many different disease end-stagemorphologic features of the so-called "different way to end by".
According to different disease pathogenesis and progression, from the organization
Morphological analysis can be divided into four types:
① peripheral type: periphery of glomerular sclerosis, hardened area often and parietalepithelial cell adhesion, children idiopathic FSGS common to this type;
② mixed type: umbilical of glomerular sclerosis with vascular hyalinization, the lesionsbegan in the vascular pole, adult idiopathic FSGS common of this type;
(3) collapse type: poor glomerular loop open, shrinkage, widely collapse of capillary loops, this type of multi-infection with the virus;
The ④ nodules: mesangial matrix increase, the formation of nodules, often accompanied by afferent arteriole hyalinization, typical morphological changes of diabetic nephropathy.
