Primary glomerular disease (PGD) remains the most common renal disease in China. A limited number of single centre studies show that the frequency of membranous nephropathy (MN) has increased; however, IgA nephropathy (IgAN) is still the most common PGD. To the best of our knowledge, there has been no multi-centre study in China that has explored the changes in PGD spectrum. To further investigate the changes in renal histopathological spectrum, we performed the cross-sectional study.
