ABSTRACT
Objective:
To identify urodynamic abnormalities in patients with cerebrovascular accidents and correlate both with CT or MRI findings. Patients andMethods:
From September 2001 to March 2003; a total of 44 males and 16 females were prospectively examined urodynamically in different phases after cerebrovascular accidents; and as early as two days after stroke.Results:
In most cases; the urodynamic findings could be correlated with CT or MRI findings. The most determining factor was the site of the lesion followed by the size. Small lesions were frequently silent unless located in critical sites. It was found that frontal; frontoparietal; parietal; basal ganglia and internal capsular ischemic lesions were associated in most cases with detrusor hyperreflexia; whereas thalamic; pontine and cerebellar infarcts were linked to detrusor hyporeflexia. Multiple lesions within the same group produced the same effect; while mixed lesions produced variable ef-fects. There was no effect of laterality or dominance and an initial shock phase could not be identified. Detrusor-sphincter-dys-synergia (DSD) and hence upper tract deterioration were not observed. The effect of stroke was also modified by already present or predominant conditions such as BPH.Conclusion:
Correlating urodynamic and CT findings is very difficult in stroke patients because of the diffuse nature of the lesions; the unknown function of many brain centers in micturition control; the innumerable connections between the different brain regions and the extremely complicated influences that the brain regions exert upon each other and upon the bladder. The optimal understanding of the problem is dependent upon the better understanding of the function of each part of the brain. Further studies in this direction are recommended
