Micturition disturbance in acute transverse myelitis.
In ten patients with acute transverse myelitis (ATM), seven patients had urinary retention, and the other three patients had difficulty in voiding within 1 month from the onset of the disease. Five of the patients with retention became able to urinate. After the mean follow-up period of 40 months, nine still had urinary symptoms including difficulty in voiding in five and urinary frequency, urgency and incontinence in four patients. Four patients had urinary disturbance as the sole sequel of ATM. Urodynamic studies performed on nine patients revealed that all of the three patients with the urgent incontinence had detrusor hyperreflexia, all of the four patients with retention had an areflexic cystometrogram as well as sphincter hyperreflexia, and three of five patients with voiding difficulty had detrusor-sphincter dyssynergia. An areflexic cystometrogram tended to change to a low compliance bladder, followed by detrusor hyperreflexia or a normal cystometrogram. Analysis of the motor unit potentials of the external sphincter revealed that two of the three patients had high amplitude or polyphasic neurogenic changes. Supranuclear as well as nuclear types of parasympathetic and somatic nerve dysfunctions seemed to be responsible for micturition disturbance in our patients with ATM.
