Spinal cord injured (SCI) patients are often placed on an intermittent catheterization (IC) program during their initial rehabilitation in an effort to establish a catheter-free state. A noninvasive method to quantitatively determine residual urine volumes would decrease unnecessary catheterizations and be useful in the management of an IC program. This study was undertaken to determine if bladder volumes could be accurately determined in a group of SCI patients using a portable ultrasound scanner. Fifteen SCI patients underwent a total of 224 ultrasonic bladder volume determinations and 57 urethral catheterizations. Immediately prior to catheterization, two investigators alternately performed a total of four ultrasound readings on each patient using a hand-held portable instrument, the BVI 2000. The first ultrasound volume determination was comparable to the average ultrasound volume (r2 = 0.956). For catheterized volumes versus the initial ultrasound volume determination, r2 = 0.80. The average error was 18% for catheterized volumes within the range 50-700ml. Our results compare favorably with both real-time scanning using standard equipment and other portable instruments. The noninvasive nature, negligible risks, and reasonable estimates of volume warrant consideration of portable ultrasound scanning for the determination of bladder volumes in SCI patients.
脊髓损伤（SCI）患者在初期康复期间常采用间歇性导尿（IC）方案，以期实现无导尿状态。一种定量测定残余尿量的非侵入性方法将减少不必要的导尿，并有助于IC方案的管理。本研究旨在确定使用便携式超声扫描仪能否在一组SCI患者中准确测定膀胱容量。15名SCI患者共接受了224次超声膀胱容量测定和57次尿道导尿。在导尿前，两名研究人员使用手持式便携式仪器BVI 2000对每位患者交替进行总共四次超声读数。首次超声容量测定与平均超声容量相当（r2 = 0.956）。对于导尿容量与初始超声容量测定，r2 = 0.80。在50 - 700ml范围内，导尿容量的平均误差为18%。我们的结果与使用标准设备的实时扫描以及其他便携式仪器相比具有优势。其非侵入性、可忽略的风险以及对容量的合理估计，使得便携式超声扫描在确定SCI患者膀胱容量方面值得考虑。
