摘　　要：目的评价超声和磁共振成像(magnetic resonance imaging,MRI)测量前列腺大小与体积的一致性。方法本研究数据来源于中国人群膀胱癌和良性前列腺增生研究数据,使用超声和MRI测量前列腺增生患者的前列腺大小与体积。前列腺的大小采用左右径、前后径和上下径表示,并根据公式计算前列腺体积。采用配对样本Wilcoxon符号秩检验进行,使用Bland-Altman分析法评估两种测量结果的一致性。结果本研究共纳入103名患者。超声测得的前列腺平均左右径、前后径、上下径分别为(5.789±0.835)cm、(5.054±0.915)cm、(4.530±0.882)cm,中位体积为66.690(49.179,96.110)mL。MRI测得的前列腺中位左右径、前后径、上下径分别为5.800(5.300,6.400)cm、5.000(4.650,5.600)cm、4.300(3.900,4.800)cm,中位体积为65.520(49.678,90.714)mL。超声与MRI测量前列腺大小结果一致性良好,二者间无统计学差异。一致性分析显示超声与MRI测量前列腺体积结果间的偏差较小,平均为1.329 mL。结论超声与MRI测量前列腺大小与体积的一致性良好,在临床实践中,应根据具体情况选择合适的前列腺大小与体积测量方法。Objective To evaluate the consistency of ultrasonography and magnetic resonance imaging(MRI)in measuring of prostate size and volume.Methods The data of this study was from the research data of the bladder cancer and benign prostatic hyperplasia study in Chinese population.The study examined the prostates of participants using both ultrasonography and MRI.Prostate size was measured by the transverse diameter,anteroposterior diameter,and supero-inferior diameter,and volume was calculated using a formula.Groups comparisons were conducted using Wilcoxon signed rank test and the consistency of measurement results was evaluated using Bland-Altman analysis.Results 103 patients with benign prostatic hyperplasia were included.The mean transverse diameter,mean antero-posterior diameter,and mean supero-inferior diameter of the prostate measured by ultrasonography was(5.789±0.835)cm,(5.054±0.915)cm,and(4.530±0.882)cm respectively,and the median volume was 66.690(49.179,96.110)mL.The median transverse diameter,median antero-posterior diameter and median supero-inferior diameter of the prostate measured by MRI was 5.800(5.300,6.400)cm,5.000(4.650,5.600)cm,and 4.300(3.900,4.800)cm respectively,and the median volume was 65.520(49.678,90.714)mL.The prostate size results had good agreement between ultrasound and MRI measurements,with no statistical difference between the two measurements.The prostate volume measured by ultrasonography had a small deviation compared to the MRI measurement,with an average difference of 1.329 mL.Conclusion The consistency between ultrasonography and MRI in measuring prostate size and volume is strong.In clinical practice,the appropriate method for measuring prostate size and volume should be chosen based on the specific circumstances.
