This document summarizes a research article that studied the clinical significance of hilar hyalinosis (HH) in the glomeruli of children with idiopathic nephrotic syndrome (INS) but without focal glomerulosclerosis (FGS). The study aimed to determine the clinic-pathological significance of HH by retrospectively analyzing cases of children with INS. HH has long been thought to be a precursor or variant of FGS, so the implications on treatment and prognosis of nephrotic syndrome were examined.
