Background and Purpose : Cerebrovascular accident is a serious neurologic event. It can have temporary or permanent effects on survivors, including memory, cognition and volitional control of voiding. The purpose of this study is to evaluate the clinical effect of moxibustion in patients with voiding dysfunction after a cerebrovascular accident. Methods : Twenty patients with post-stroke voiding dysfunction were studied. All patients had computerized tomography(CT) and magnetic resonance imaging(MRI) to localize the lesion in the central nervous system. They were randomly divided into two groups : the control and moxibustion group. Ten of twenty patients underwent moxibustion treatment by randomization. The moxibustion group receieved moxibustion at three points : Chung-guk (Conception Vessel CV3), Kuanwon (CV4) Kihae (CV6). Residual urine volume evaluation was undertaken in all patients. Results : 1. IIn the balanced bladder time, the moxibustion group had the shorter time than non moxibustion group. But there was no significiant difference between the moxibustion group and non-moxibustion group. 2. In the residual urine volume, the moxibustion group and non-moxibustion group showed a tendency to decrease. But there was no significiant difference between the moxibustion group and non-moxibustion group. Conclusions : Though further study is needed, our findings suggested that the time of achieving balanced voiding was shorter with moxibustion than in the control group.
