Patterns of Voiding Dysfunction of Stroke Patients during Rehabilitation

ABSTRACT

OBJECTIVE: The purpose of this study is to evaluate the patterns of voiding dysfunction of stroke patients during rehabilitation. METHOD: We evaluated 53 patients with complaints of voiding dysfunction following the strokes. After the comprehensive history and physical examination, all patients underwent cystometric study and males underwent the transrectal ultrasound. RESULTS: The incidences of detrusor hyperreflexia, detrusor areflexia, and normal finding on the cystometry were 50.9%, 32.1%, and 17.0%, respectively (p<0.05). There was a significantly high incidence of detrusor hyperreflexia in the groups of subcortical lesion, large lesion, and the over 3 months after stroke (p<0.05). However, there was no statistical difference on cystometric findings according to the other characteristics of the stroke such as the age, sex, type of stroke, cognition, aphasia, and diabetes mellitus. The incidences of irritative, obstructive, and mixed symptoms according to the presenting voiding complaints were 49.1%, 32.1%, and 18.9%, respectively (p<0.05). There was no significant statistical difference on the cystometric findings according to the 3 voiding symptom groups as well as none of significant statistical difference on prostate enlargement in males in according to the 3 voiding symptom groups. CONCLUSION: Only with the pattern of voiding, we could not predict the cystometric finding or the presence of bladder outlet obstruction. Thus, we recommend the further studies including cystometry and evaluation of the bladder outlet obstruction for the treatment of voiding dysfunction of stroke patients during rehabilitation.
