Glomerulonephritis (GN) is the leading cause of end-stage renal disease in 30% to 50% of patients who receive a renal transplant. The exact prevalence of either recurrent or de novo GN is unknown since a considerable number of patients never undergo allograft biopsy, leaving GN underdiagnosed. The aim of this study is to evaluate the effects of recurrent GN on the prevalence, risk factors, clinicopathological features, and outcome of renal transplant recipients.
