Neurogenic bladder dysfunction in protruded lumbar disk and after laminectomy.

J T Andersen, W E Bradley

    Urology
    |July 1, 1976

    Summary

    Neurogenic bladder dysfunction is common in patients with lumbar disk issues or after laminectomy. Detrusor muscle problems were frequent, but sphincter issues were rare, indicating often irreversible nerve damage.

    Area of Science:

    • Urology
    • Neurology
    • Neurosurgery

    Background:

    • Lumbar disk herniation and post-laminectomy complications can affect the cauda equina.
    • Nerve damage to the bladder and urethra can lead to significant functional impairment.

    Purpose of the Study:

    • To investigate bladder and urethral innervation in patients with lumbar disk issues or post-laminectomy pain.
    • To determine the incidence and nature of neurogenic dysfunction in these patient groups.

    Main Methods:

    • Study included 18 patients with protruded lumbar disk or persistent back pain after laminectomy.
    • Assessment focused on bladder and urethral innervation, specifically detrusor muscle and external urethral sphincter function.

    Main Results:

    • A high incidence of neurogenic dysfunction affecting the detrusor muscle was observed.
    • Impaired function of the striated external urethral sphincter was found to be rare.
    • Lesions were present in both patient groups, suggesting common underlying mechanisms.

    Conclusions:

    • Neurogenic bladder dysfunction is a frequent complication in cauda equina injury from protruded lumbar disks.
    • The observed detrusor muscle dysfunction is often irreversible.
    • Further research may explore management strategies for irreversible neurogenic bladder dysfunction.
