Correlation of Voiding Dysfunction with the Lesion Site of Cerebrovascular Accident / 대한비뇨기과학회지

ABSTRACT

PURPOSE: Cerebrovascular accident is a serious neurological event, it can have temporary or permanent effects on survivors, including memory, cognition and volitional control of voiding. However, the correlation between the brain lesion site and type of voiding dysfunction is less well understood. This study was performed to evaluate the type of voiding dysfunction on the anatomic lesion of brain in patients with urinary symptoms after a cerebrovascular accident. MATERIALS AND METHODS: Urodynamic evaluation was undertaken in 74 patients who had suffered from voiding dysfunction. Computerized tomography(CT) and magnetic resonance imaging(MRI) were performed to localize the lesion in central nervous system. RESULTS: Damage to basal ganglia and/or internal capsule(6 of the 11 patients) and cerebral cortex(12 of the 21 patients) showed frequent detrusor hyperreflexia, while multiple lesion(21 of the 39) exhibited frequent detrusor areflexia. Uninhibited relaxation of sphincter in detrusor hyperreflexia was only observed in cerebral cortex lesion. CONCLUSIONS: Correlation of bladder dysfunction with the anatomical lesion of cerebrovascular accident was not conclusive, but was suggestive of directions to be taken in the future studies for the improvement of the life quality and preservation of renal function
