The assessment of intravesical urine volume is very important in the management of the patients with lower urinary tract obstruction or incontinence. As the non-invasive method for measuring residual urine volume, accuracy and usefulness of ultrasonographic measurement was evaluated in a total of 116 occasions in comparison with the conventional catheter technique. The values of the maximum transverse (W), cranio-caudal (H) and antero-posterior distance (D) of the inflated bladder were obtained by trans-abdominal scanning. These parameters were used for the ellipsoid formula (pi/6 x W x H x D). The ultrasonographic measurement of urine volume showed a high coefficiency against the conventional catheterized volume (r = 0.9543). Although a mean standard error was 56.3% of the actual volume, the amount of residual urine at the target of 50 ml and 100 ml could be accurately assessed by ultrasound with an accuracy of 90.5%. The method was also valid in follow-up study to monitor the changes of residual urine volume. The ultrasonographic assessment of intravesical urine volume is, thus, a non-invasive, useful tool in the management of the patients with voiding disturbance.
膀胱内尿量的评估在膀胱出口梗阻或尿失禁患者的管理中非常重要。作为测量残余尿量的非侵入性方法，与传统的导尿技术相比，共116次评估了超声测量的准确性和实用性。通过经腹部扫描获得充盈膀胱的最大横径（W）、头-尾径（H）和前后径（D）值。这些参数用于椭圆体公式（π/6×W×H×D）。超声测量尿量与传统导尿测量的相关性较高（r = 0.9543）。虽然平均标准误差为实际尿量的56.3%，但超声可准确评估目标残余尿量为50 ml和100 ml时的尿量，准确率为90.5%。该方法在监测残余尿量变化的随访研究中也有效。因此，超声评估膀胱内尿量是一种用于管理排尿障碍患者的非侵入性有用工具。
