Figure 3 A case of renal allograft since 6 years with serum creatinine=2.9 mg% and eGFR=19 ml/min. (a) Fibroscan score 41 pKa. (b) Gray-scale ultrasound shows grade II increase in echogenicity of the graft with cortical thickness=1.2 cm and longitudinal diameter=8 cm. (c) Doppler examination of the interlobar arteries shows RI=1.0. (d) Graft biopsy shows mild interstitial fibrosis and tubular atrophy according to Banff grade 3. eGFR, estimated glomerular filtration rate; RI, resistive index.
