Flow chart of TG patients enrolled in the study. There were a total of 2,375 indication biopsies were performed due to elevated creatinine and/or proteinuria from 2000 to 2018 in our center. TG-lesions were found in 346 biopsies from 251 kidney transplant recipients. Biopsy cases with recurrent/de novo glomerulonephritis (n = 32), TMA (n = 31), hepatitis C-virus associated MPGN (n = 2) were excluded. After further excluding the patients with mTOR inhibitors-induced proteinuria (PU ≥ 0.3 g/day, n = 21), a total of 165 patients were enrolled in our study. TG, transplant glomerulopathy; cg, chronic allograft glomerulopathy; TMA, thrombotic microangiopathy; MPGN, membranoproliferative glomerulonephritis; mTOR, mammalian target of rapamycin; PU, proteinuria.
