    Urological Research
    |January 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Double CO2-cystometry showed consistent results in most patients. However, eight individuals exhibited different cystometrogram types, suggesting potential variability in bladder function assessment.

    Area of Science:

    • Urology
    • Medical Diagnostics
    • Physiology

    Background:

    • Bladder function assessment is crucial for diagnosing lower urinary tract symptoms.
    • Carbon dioxide (CO2)-cystometry is a diagnostic tool for evaluating bladder capacity and function.
    • Understanding the reproducibility of CO2-cystometry is important for clinical application.

    Purpose of the Study:

    • To evaluate the reproducibility of double, rapid fill CO2-cystometry.
    • To identify potential variations in cystometrogram types between repeated measurements.

    Main Methods:

    • 114 consecutive patients underwent two rapid fill CO2-cystometry procedures.
    • Cystometrograms were analyzed for type and key urodynamic parameters.
    • Statistical analysis was performed to compare results from the two cystometries.

    Main Results:

    • In 106 out of 114 patients (93%), the two CO2-cystometries yielded the same cystometrogram type.
    • Statistically significant changes in several cystometric values were observed between the two tests in the majority of patients.
    • Eight patients (7%) showed different cystometrogram types, with uninhibited detrusor contractions present in one but not the other.

    Conclusions:

    • Double, rapid fill CO2-cystometry demonstrates high consistency in classifying bladder function type.
    • Despite consistent types, significant variations in urodynamic parameters can occur between repeated CO2-cystometry sessions.
    • The observed discrepancies in a small subset of patients warrant further investigation into factors influencing detrusor activity variability.
