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 personal digital assistance (PDA) device and compared its clinical utilities while applying this device to both natural and artificial filling cystometry study. The range of errors of the pressure signals measured our constructed device was less than 1 cmH₂O, and the reproducibility of two pressure channels were 2.32plusmn2.97 and 3.67 plusmn5.31 %, 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.
