Objective To observe the clinical efficacy of turtle-shell-insulated moxibustion combined with acupuncture at Baliao points in treating difficult catheter removal in poststroke urinary retention. Methods Eighty patients with poststroke urinary retention experiencing difficult catheter removal were randomly allocated to an observation group and a control group using the random number table method, each consisting of 40 cases. The control group received intermittent catheterization, based on which, the observation group additionally received turtle-shell-insulated moxibustion plus acupuncture at Baliao points 5 times weekly. The number of successful catheter removals after 1, 2, and 3 weeks of treatment, respectively, the postvoid residual urine volume before and after 1, 2, and 3 weeks of treatment, bladder safe volume, end-filling bladder resting pressure, and bladder compliance before and after 2 weeks of treatment were recorded. Adverse reactions that occurred during the treatment period were observed. Results There was no significant difference in the number of successful catheter removals between the observation group and control group after 1 week of treatment (P>0.05); the observation group had more successful catheter removals than the control group after 2 and 3 weeks of treatment (P<0.05). The between-group difference in the postvoid residual urine volume was statistically insignificant at treatment week 1 (P>0.05), while the residual volume was smaller in the observation group than in the control group at treatment weeks 2 and 3 (P<0.05). Compared to the control group, the observation group had lower bladder safe capacity and compliance (P<0.01) and higher end-filling bladder resting pressure (P<0.01) after 2 weeks of treatment. During the treatment period, the observation group had a lower adverse reaction rate than the control group (P<0.05). Conclusion Based on intermittent catheterization, turtle-shell-insulated moxibustion plus acupuncture at Baliao points can increase the success rate of urine catheter removal and lower the adverse reaction rate in patients with poststroke urinary retention. The mechanism may be associated with elevating the end-filling bladder resting pressure and decreasing bladder safe capacity, thus restoring normal bladder compliance and reducing residual urine volume.

摘要

Objective

To observe the clinical efficacy of turtle-shell-insulated moxibustion combined with acupuncture at Baliao points in treating difficult catheter removal in poststroke urinary retention.

Methods

Eighty patients with poststroke urinary retention experiencing difficult catheter removal were randomly allocated to an observation group and a control group using the random number table method, each consisting of 40 cases. The control group received intermittent catheterization, based on which, the observation group additionally received turtle-shell-insulated moxibustion plus acupuncture at Baliao points 5 times weekly. The number of successful catheter removals after 1, 2, and 3 weeks of treatment, respectively, the postvoid residual urine volume before and after 1, 2, and 3 weeks of treatment, bladder safe volume, end-filling bladder resting pressure, and bladder compliance before and after 2 weeks of treatment were recorded. Adverse reactions that occurred during the treatment period were observed.

Results

There was no significant difference in the number of successful catheter removals between the observation group and control group after 1 week of treatment (P>0.05); the observation group had more successful catheter removals than the control group after 2 and 3 weeks of treatment (P<0.05). The between-group difference in the postvoid residual urine volume was statistically insignificant at treatment week 1 (P>0.05), while the residual volume was smaller in the observation group than in the control group at treatment weeks 2 and 3 (P<0.05). Compared to the control group, the observation group had lower bladder safe capacity and compliance (P<0.01) and higher end-filling bladder resting pressure (P<0.01) after 2 weeks of treatment. During the treatment period, the observation group had a lower adverse reaction rate than the control group (P<0.05).

Conclusion

Based on intermittent catheterization, turtle-shell-insulated moxibustion plus acupuncture at Baliao points can increase the success rate of urine catheter removal and lower the adverse reaction rate in patients with poststroke urinary retention. The mechanism may be associated with elevating the end-filling bladder resting pressure and decreasing bladder safe capacity, thus restoring normal bladder compliance and reducing residual urine volume.
