The aim was to evaluate bladder volume measurement using computerized calculation in comparison with usual formulas. Twenty-eight volunteers underwent bladder ultrasonography, which was recorded for computerized measurement of bladder volume. From diameters and/or areas measurements, bladder volume was calculated using 12 different formula. True bladder volume was obtained from voided volume measurement. Computerized measurement was not more accurate than formulas. No formulas displayed association of low percentage error and standard deviation and good accuracy. The best accuracy was obtained with the combined formula F12 ([(DSc x DAPc x DT x 0.523) + (DT x AS)]/2). Formula (F4) using the three diameters, with reference to anterior bladder recessus and 0.625 correction factor displayed good results on the average.
目的是评估使用计算机计算测量膀胱容量并与常用公式进行比较。28名志愿者接受了膀胱超声检查，记录检查结果用于计算机测量膀胱容量。通过测量直径和/或面积，使用12种不同公式计算膀胱容量。真实膀胱容量通过排尿量测量获得。计算机测量并不比公式更准确。没有公式显示出低百分比误差和标准差与良好准确性之间的关联。联合公式F12（[(DSc×DAPc×DT×0.523)+(DT×AS)]/2）获得了最佳准确性。参照膀胱前隐窝使用三个直径并采用0.625校正因子的公式（F4）平均显示出良好结果。
