Table 1. Kidney volumes for healthy and UNX rats estimated by weighting, water displacement and manual segmentation of MR images.
group | Kidney weight [g] | Water displacement [ml] | Cortical volume - MRI [ml] | Total volume – MRI [ml] | Mean tubular flow – MRI [ml/100 ml/min] | |||||
right | left | right | left | right | left | right | left | right | left | |
SD | 1.36 (±0.13) | 1.42 (±0.12) | 1.40 (±0.12) | 1.41 (±0.11) | 1.42 (±0.25) | 1.50 (±0.26) | 1.95 (±0.34) | 2.17 (±0.34) | 68 (±37) | 61 (±35) |
UNX | 1.76 (±0.38) | 1.74 (±0.33) | 1.63 (±0.45) | 2.40 (±0.43) | 73 (±18) |
Unilateral nephrectomy was performed on the left kidney. In case of the MRI, also cortical volumes were estimated for GFR calculations. Values are mean ± standard deviation.
