title: Early detection of neurogenic bladder dysfunction caused by protruded lumbar disk.
abstract: A case of cauda equina compression was suspected from urinary symptoms. The diagnosis was based on the presence of type A contraction on rapid cystometry and prolonged latency of the sacral evoked response. Such findings pointed to the need for myelography. Lumbar laminectomy, with removal of a ruptured intervertebral disk and cauda equina decompression, resulted in return of normal urination and normal cystometry and electromyogram of the perineal muscles.
