Urodynamic studies on hemiplegic patients after cerebrovascular accident.

Thirty-nine hemiplegic patients were evaluated by complete urodynamic study after cerebrovascular accidents. Computerized tomography was performed to identify localization of the brain lesion. The common urinary symptoms were frequency and urgency incontinence (26/39), while 13 patients complained of dysuria or urinary retention. Ten of the 11 patients who had frontal and internal capsular lesions showed hyperactive bladder, and 6 showed uninhibited sphincter relaxation. Nine of the 10 patients who had putaminal lesions showed hyperactive bladder. Normal sphincter activity was demonstrated in 7 of these 10 patients. In the remaining patients with the other types of lesions, no correlation was found between urodynamic dysfunction and type of brain injury.
