Abstract
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.
