Abstract

OBJECTIVE:

To observe the urodynamic profile of the patients following non-traumatic myelopathies (NTMs) with neurogenic bladder.

SETTING:

Neurological rehabilitation department of university tertiary research hospital.

MATERIALS AND METHODS:

Seventy-nine patients (44 men) with monophasic NTM, with the age range 8-65 years (31.0 ± 16.0 years), were admitted for inpatients' rehabilitation. Length of stay in rehabilitation ranged from 6 to 120 days (32.0 ± 24.8 days). Fifty-six patients (70.9%) had spinal lesion above D10, 17 had lesion between D10 and L2 (21.5%), and 6 (7.6%) had cauda equina syndrome. All patients had neurogenic bladder with urinary complaints. Urodynamic study (UDS) was performed in all patients.

RESULTS:

UDS showed 71.4% patients (40/56) had neurogenic detrusor overactivity (NDO) with or without sphincter dyssynergy (DSD) with lesion above D10; only 52.9% patients (9/17) had NDO with or without DSD detrusor with lesion between D10 and L2; and majority (5/6 patients) had underactive detrusor in the cauda equina group. Bladder management was based on the UDS findings. No significant correlation was found (P > 0.05) between detrusor behavior and the level, severity (ASIA Impairment Scale) of spinal injury, or gender using chi-square test.

CONCLUSIONS:

Neurogenic bladder following NTM was observed in all patients. UDS suggested predominantly NDO in lesions above D10 and mixed pattern in between D10 and L2 lesions. No significant correlation was found between detrusor behavior and the level or severity of NTM in the study.
