This study assessed the accuracy and precision of a portable ultrasound unit which computes bladder volume after scans are made in the sagittal and transverse planes. 39 ultrasound measures were made on 20 children between the ages of one month and 16 years, and these measures were then compared with catheterized volumes. The mean difference of ultrasound minus true volume was 6.9 ml (SD 32ml). The ultrasound scanner was found to be accurate, inexpensive and easy to use for measuring post-voiding residual urine volumes in children with neurogenic bladder.
本研究评估了一种便携式超声设备的准确性和精确性，该设备在矢状面和横断面上进行扫描后计算膀胱容积。对20名年龄在1个月至16岁之间的儿童进行了39次超声测量，然后将这些测量结果与导尿测量的容积进行比较。超声测量值减去实际容积的平均差值为6.9毫升（标准差32毫升）。结果发现，该超声扫描仪在测量神经源性膀胱患儿的排尿后残余尿量方面准确、廉价且易于使用。
