[Incontinence following prostatectomy]

D Hauri

    Urologia Internationalis
    |January 1, 1982
    PubMed
    Summary
    This summary is machine-generated.

    Urinary continence relies on the bladderneck and proximal urethra, not the external sphincter. Prostatectomy can impair these structures, potentially leading to incontinence due to surgical technique or prostate growth.

    Area of Science:

    • Urology
    • Anatomy
    • Physiology

    Context:

    • Urinary continence is crucial for quality of life.
    • Prostatectomy significantly impacts urinary control mechanisms.
    • Understanding the anatomy of the bladderneck and urethra is key.

    Purpose:

    • To elucidate the anatomical and physiological basis of urinary continence.
    • To identify the structures responsible for maintaining continence post-prostatectomy.
    • To highlight factors contributing to urinary incontinence after prostate surgery.

    Summary:

    • Urinary continence is maintained by the bladderneck and proximal urethra, primarily involving smooth muscles.
    • The striated external sphincter plays a minimal role in continence.
    • Prostatectomy removes critical smooth muscle structures, leaving a small distal urethral segment responsible for continence, which can be compromised by prostate growth or surgical error.
