The effect of prostatectomy on urodynamic parameters.

M M Rao, R Ryall, C Evans

    British Journal of Urology
    |August 1, 1979
    PubMed
    Summary

    Unstable bladders affect 60% of men post-prostatectomy, often linked to catheters or obstruction. However, these factors showed minimal impact on prostatectomy outcomes or urine flow rates.

    Area of Science:

    • Urology
    • Surgical Outcomes

    Background:

    • Prostatectomy is a common procedure for benign prostatic hyperplasia and prostate cancer.
    • Urinary incontinence and bladder dysfunction are potential complications following prostatectomy.

    Purpose of the Study:

    • To investigate the incidence of unstable bladders after prostatectomy.
    • To identify factors associated with post-prostatectomy bladder instability.
    • To assess the relationship between bladder function and prostatectomy outcomes.

    Main Methods:

    • Retrospective analysis of patients undergoing prostatectomy.
    • Assessment of bladder instability using clinical evaluation.
    • Measurement of functional urethral pressure profile length.
    • Correlation analysis with prostate size, catheter use, obstruction, and urine flow rates.

    Main Results:

    • Sixty percent of men experienced bladder instability post-prostatectomy.
    • Bladder instability was associated with indwelling catheters or bladder outlet obstruction.
    • No significant correlation was found between functional urethral pressure profile length and prostate gland size.
    • Prostatic plateau shortening was consistently observed, but its extent did not correlate with urine flow rates.

    Conclusions:

    • Bladder instability is a frequent occurrence after prostatectomy, primarily linked to catheterization or obstruction.
    • These factors, while contributing to instability, do not significantly influence the overall success of the prostatectomy procedure itself.
    • Urethral pressure profile characteristics show limited correlation with prostate size or urine flow rates in this cohort.
