The neuropathic urethra

N O Gibbon, K F Parsons, K A Woolfenden

    Paraplegia
    |August 1, 1980

    Summary
    This summary is machine-generated.

    Functional urethral obstruction may stem from urethral supersensitivity after sympathetic decentralization. A new postural test reveals this denervation in central and peripheral nerve damage, and sometimes in localized visceral neuropathy.

    Area of Science:

    • Urology
    • Neurology
    • Physiology

    Background:

    • Functional urethral obstruction is often observed in neuropathic conditions.
    • The underlying mechanisms, particularly the role of sympathetic nervous system changes, require further elucidation.

    Purpose of the Study:

    • To test the hypothesis that urethral supersensitivity following sympathetic decentralization contributes to functional urethral obstruction.
    • To introduce and validate a simple postural test for assessing this condition.

    Main Methods:

    • A novel postural test was developed to evaluate urethral denervation.
    • The test was applied to patients with neuropathic states and those with peripheral nerve damage.

    Main Results:

    Related Experiment Videos

  • The study demonstrated urethral denervation in patients with central nervous system disorders.
  • Peripheral nerve damage, including that from rectal excision and hysterectomy, also resulted in urethral denervation.
  • Functional urethral obstruction was observed in some cases without identifiable neurological abnormalities, suggesting localized visceral neuropathy.

    • Conclusions:

    • Sympathetic decentralization and subsequent urethral supersensitivity are implicated in functional urethral obstruction.
    • The developed postural test is effective in identifying urethral denervation.
    • Localized visceral neuropathy may present as functional urethral obstruction without overt neurological deficits.
