Abdominal venous congestion alters renal morphometry.

<p>Glomerular surface area (A), width of Bowman’s space (B), glomerular density (C) and quantification of total collagen from renal sections (D) of sham-operated (SHAM, n = 6) and IVC-constricted rats (IVCc, n = 7). Based on the Shapiro-Wilk normality test, data were analyzed using an unpaired t-test (A, C and D) or a Mann-Whitney test (B). Data are shown as median, minimum and maximum. * denotes p < 0.05, ** denotes p < 0.01. IVC = inferior vena cava, IVCc = IVC-constricted rats.
