Despite disadvantages such as time-consuming and tedious to the user, planimetric volumetry is considered to be the most accurate method for prostate volume determination. This study investigates the possibilities of formula-derived volume determination and reveals the best alternative to planimetric volumetry.
The prostate volume is calculated using prostatic dimensions (length, height and width) in four mathematical descriptions for prostate volume calculations. As reference, the planimetric results obtained with 4 mm step size were used.
Compared to the results of planimetric volumetry obtained with 4-mm intersection distance, the best results for volume determination with mathematical calculation were obtained with a formula describing a spheroid volume using half the mean of width, height and length as radius.
Although planimetric volumetry remains the most accurate method for prostate volume determination, the spheroid formula is the best alternative method for quick volume assessment with reasonable accuracy.
尽管平面容积测量法对使用者来说存在耗时且繁琐等缺点，但它仍被认为是测定前列腺体积最准确的方法。本研究探讨了公式推导体积测定法的可能性，并揭示了平面容积测量法的最佳替代方法。
采用前列腺尺寸（长度、高度和宽度），通过四种数学描述方法计算前列腺体积。作为参考，使用步长为4毫米时获得的平面测量结果。
与步长为4毫米时获得的平面容积测量结果相比，用宽度、高度和长度平均值的一半作为半径来描述球体体积的公式进行数学计算，在体积测定方面取得了最佳结果。
尽管平面容积测量法仍是测定前列腺体积最准确的方法，但球体公式是进行快速体积评估且具有合理准确性的最佳替代方法。
