AIM
To assess urinary bladder volume in a noninvasive manner using a portable and modified device that measures electrical impedance.
METHODS
A novel method was attempted to measure electrical impedance and indirect bladder volume, and these data were used to calculate the actual bladder volume.
RESULTS
An increase of 0.01 V in the abdominal voltage was observed with every 50 mL increase in the amount of physiological saline infused into the bladder.
CONCLUSIONS
It is a simple procedure and can be used by technical staff or the patients themselves to obtain continuous, real-time urinary bladder volume data.
目的
使用一种便携的改良装置以无创方式评估膀胱容量，该装置可测量电阻抗。
方法
尝试采用一种新方法来测量电阻抗和间接膀胱容量，并利用这些数据计算实际膀胱容量。
结果
向膀胱内注入的生理盐水每增加50 mL，腹部电压就会升高0.01 V。
结论
这是一个简单的操作，技术人员或患者自身均可使用，以获取连续、实时的膀胱容量数据。
