A study was undertaken to determine the effect of body position on ultrasonographic bladder measurements and volume estimations. Of the 42 dogs studied, 15 were fresh canine cadavers without urological disease and the remaining 27 were undergoing investigations for disorders of the lower urinary tract. Bladder volume was estimated using a formula described previously. Irrespective of whether all dogs were considered together or only live animals were included, measurements made in dorsal recumbency tended to underestimate bladder volume while those made in right lateral recumbency resulted in overestimation. This was due to significant differences in all linear measurements, apart from width, between body positions. Measurements in right lateral recumbency were higher than those in dorsal recumbency. In all animals and in living dogs alone, bladder measurements in dorsal recumbency appeared to give a more accurate estimation of actual bladder volume.
进行了一项研究以确定体位对超声膀胱测量和容积估计的影响。在研究的42只狗中，15只是没有泌尿系统疾病的新鲜犬类尸体，其余27只正在接受下尿路疾病的检查。膀胱容积使用先前描述的公式进行估计。无论将所有狗一起考虑还是仅包括活体动物，仰卧位测量往往会低估膀胱容积，而右侧卧位测量则会导致高估。这是由于除宽度外，各体位之间所有线性测量存在显著差异。右侧卧位的测量值高于仰卧位。在所有动物以及仅活体狗中，仰卧位的膀胱测量似乎能更准确地估计实际膀胱容积。
