Objective To observe the effect of navel acupuncture on bladder emptying function in patients with urinary retention after stroke based on the conventional treatment. Methods A total of 106 patients with urinary retention after stroke were randomly divided into an observation group（53 cases

3 cases dropped off） and a control group（53 cases

3 cases dropped off）. Patients in the control group were treated with drugs

catheterization and bladder function rehabilitation training. On the basis of the treatment in the control group

the observation group was treated with navel acupuncture

30 min each time

once every other day

for 4 weeks. The bladder residual urine volume

spontaneous urination volume and catheterization times before and after treatment were compared between the two groups

and the clinical efficacy was evaluated. Results After treatment

in the two groups

the bladder residual urine volume and catheterization times were lower than those before treatment（P<0.01）

and the spontaneous urination volume was higher than that before treatment（P<0.01）; the bladder residual urine volume and catheterization times in the observation group were less than those in the control group（P<0.05

P<0.01）

and the spontaneous urination volume was higher than that in the control group（P<0.01）. The effective rate of the observation group was 90.0 %（45/50）

which was higher than 72.0 %（36/50） in the control group（P<0.05）. Conclusion On the basis of conventional treatment

navel acupuncture can effectively improve the bladder emptying function of patients with urinary retention after stroke.
