tethered cord syndrome
Neurological condition where the spinal cord is abnormally attached, causing progressive neurological symptoms including bladder dysfunction.
Full Definition
A progressive neurological condition characterized by abnormal attachment of the spinal cord to surrounding structures, preventing normal movement of the cord within the spinal canal during growth and development. The tethering creates tension on neural elements, leading to progressive neurological dysfunction including lower urinary tract symptoms, lower extremity weakness, sensory deficits, and orthopedic deformities. Urological manifestations may include neurogenic bladder, incontinence, recurrent infections, and upper tract deterioration. Diagnosis is confirmed through MRI imaging showing a low-lying conus medullaris, and treatment involves surgical release of the tethering tissue to prevent further neurological deterioration.
Usage
Usage note: Specify conus level and associated urological findings when documenting.
