Urinary bladder reinnervation.

B Vorstman, S M Schlossberg, L Kass

    The Journal of Urology

    Summary
    This summary is machine-generated.

    This study shows that connecting lumbar (L7) and sacral (S1) nerve roots can help regenerate nerves to the urinary bladder. This nerve regeneration technique may help treat neurogenic bladder dysfunction.

    Area of Science:

    • Neuroscience
    • Urology
    • Regenerative Medicine

    Background:

    • Neurogenic bladder dysfunction affects bladder control.
    • Restoring bladder innervation is crucial for treatment.

    Purpose of the Study:

    • To investigate the potential for mixed spinal nerve root regeneration and bladder reinnervation.
    • To assess the efficacy of lumbar-to-sacral nerve root anastomosis in cats.

    Main Methods:

    • Microsurgical technique involving unilateral extradural spinal nerve root anastomosis (L7 to S1) with or without nerve grafts.
    • Transection of ipsilateral sacral roots and preservation of contralateral roots for control.
    • Electrophysiological and cystometric assessments seven months post-surgery.

    Main Results:

    Related Experiment Videos

    • Bladder contractions were elicited upon stimulation of the anastomosed nerve root.
    • Significant lumbar axonal regeneration and redirection to sacral pathways were confirmed.
    • Successful reinnervation of the urinary bladder was demonstrated.

    Conclusions:

    • Anastomosis of lumbar and sacral nerve roots promotes significant bladder reinnervation.
    • This surgical approach holds potential for treating neurogenic bladder dysfunction.
    • Restoration of bladder function and central control may be achievable.
