Abstract
A conventional voiding cystometry involves artificially filling the bladder with saline and reproduce their symptoms, while making precise measurements in order to identify their underlying causes. However, it is difficult to evaluate physiological functions during storage and voiding of the bladder. In this study, we constructed a portable cystometry device based on hand-held mobile computer, personal digital assistance (PDA), and evaluated its clinical utilities while applying this device to natural filling cystometry study. The range of errors of the pressure signals measured our constructed device was less than 1 cm H2O, and the reproducibility of two pressure channels were 2.32 plusmn 2.97 and 3.67 plusmn 5.31 %, respectively. Also, the clinical assessment of our device showed that the system has the capability to accurately monitor the types of information that contribute to the diagnosis and management of patients.
传统的排尿膀胱术包括人工地用生理盐水填充膀胱并重现其症状，同时进行精确的测量以确定其潜在原因。然而，膀胱在储存和排尿过程中的生理功能难以评估。在本研究中，我们构建了一种基于手持移动计算机、个人数字辅助(PDA)的便携式膀胱造口仪，并评估了其在自然充盈膀胱造口研究中的临床应用。该装置测得的压力信号误差范围小于1 cm H2O，两个压力通道的重现性分别为2.32±2.97和3.67±5.31%。此外，对我们设备的临床评估表明，该系统具有准确监测有助于患者诊断和管理的信息类型的能力。
