[Efficacy of electroacupuncture combined with penetrating moxibustion for postpartum stress urinary incontinence]

Abstract

Objective: To compare the clinical effect differences between electroacupuncture (EA) combined with penetrating moxibustion and the biological feedback training of pelvic floor muscle for postpartum stress urinary incontinence (SUI).

Methods: Sixty patients of SUI who had delivery 42 days ago were randomly divided into an observation group and a control group, 30 cases in each one. The observation group was treated with EA and penetrating moxibustion. EA was applied at Ciliao (BL 32) and Huiyang (BL 35), combined with acupuncture at Qihai (CV 6), Zhongji (CV 3), Zigong (EX-CA 1), Zusanli (ST 36) and Sanyinjiao (SP 6); penetrating moxibustion was performed on abdomen and lumbosacral area. The control group was treated with biological feedback training of pelvic floor muscle. Both the groups were treated once every other day, 3 times per week for continuous 6 weeks. The International Consultation on Incontinence Questionnaire-Short Form (ICI-Q-SF), 1 h urinal pad test and pelvic floor muscle strength were tested before and after treatment; the efficacy was evaluated after treatment and at 6-month follow-up visit.

Results: Compared before treatment, the ICI-Q-SF score and 1 h urine leakage were significantly reduced after treatment in the two groups (P<0.01), and the reduction in the observation group was superior to that in the control group (P<0.05). Compared before treatment, the pelvic muscle strength of muscle fibers Ⅰand Ⅱ were significantly increased after treatment in the two groups (P<0.01), and the differences between the two groups had no statistical significance (P>0.05). After treatment, the cured rate and total effective rate were 70.0% (21/30) and 96.7% (29/30) in the observation group, which were superior to 33.3% (10/30) and 70.0% (21/30) in the control group (P<0.01); in the 6-month postpartum period, the cured rate and total effective rate were 63.3% (19/30) and 93.3% (28/30) in the observation group, which were superior to 30.0% (9/30) and 66.7% (20/30) in the control group (P<0.05).

Conclusion: EA combined with penetrating moxibustion could improve the urinary control ability, relieve the symptoms of urinary incontinence and have a better long-term effect in patients with postpartum SUI, which is superior to biological feedback training of pelvic floor muscle.
