Objective: To evaluate the usefulness of a newly devised portable cystometer to measure the pressure of bladder in a low cost and easier accessability.
Method: This study was performed in 47 patients with a conventional instrumental cystometer (Jupiter 8000, Wiest) and the newly devised portable cystometer. In the supine position, we measured the maximal intravesical pressure, abdominal pressure
bladder volume with the portable cystometer just after the measurement of the maximal detrusor pressure and bladder volume with the conventional instrumental cystometer. Paired t-test was utilized to analyze and compare the result.
Results: 1) There was no significant difference in the average maximal detrusor pressures measured by maximal intravesical pressures minus abdominal pressures, which were 38.32 ± 20.97 cmH2O by the conventional instrumental cystometer
40.02 ± 20.70 cmH2O by the portable cystometer (p＞0.05). 2) There was no significant difference in the average bladder volumes at maximal detrusor pressure, which were 302.13 ± 83.92 cc by the conventional instrumental cystometer and 314.04 ±
cc by the portable cystometer (p＞0.05).
Conclusion: We conclude that there is no significant difference between the conventional instrumental cystometer and the portable cystometer in the measurement of detrusor pressure and bladder volume. We believe this portable cystometer would be
useful tool to evaluate the function of bladder in a low cost and easier accessability.
