Trends of elasticity variation of the renal cortex, medulla and sinus with different perfusion pressures of the renal artery and ligation status in ex vivo. The curves and histograms show the variation of YM in each compartment when different perfusion pressures were applied under no ligation (a, d), ligation of the renal vein only (b, e) and ligation of both the renal vein and ureter (c, f), respectively. Data are expressed as the mean ± SD. Intergroup comparisons were performed by paired t-test. **P < 0.01
