Posttransplant glomerulonephritis (PTGN) is the third most common cause of late allograft loss. This could be classified into recurrent or de novo PTGN. The prevalence of PTGN is about 6–8%. There are several challenges with the diagnosis of PTGN. In addition, these diseases are not common, mostly described in case reports, case series and registry analysis. The reports vary in their definitions and approach to diagnosis. There is no high quality evidence for management of these conditions. This review focuses on summarizing the current evidence on the prevalence, clinical features, risk factors and management of PTGN.
