Objective:
To explore the clinical efficacy of electroacupuncture nerve stimulation therapy (ENST) for interstitial cystitis/painful bladder syndrome (IC/PBS).
Methods:
A total of 68 patients with IC/PBS were randomly divided into an observation group and a control group, 34 cases in each one. The patients in the observation group were treated with ENST; abdominal four acupoints and sacral four acupoints were connected with a pair of electrodes and treated alternately every other day. The ENST was given 50 min per times, three times a week for 3 months. The patients in the control group were treated with perfusion therapy of four-medication combination (heparin sodinm, lidocaine, sodium bicarbonate, gentamicin sulfate), twice a week for the first 6-8 weeks, followed by twice per month for 3 months. The infusion fluid remained for 1 h before discharging. The O' Leary-Sant score, including interstitial cystitis symptom index (ICSI) and interstitial cystitis problem index (ICPI), 24 h urination frequency, visual analogue scale (VAS) and maximum bladder volume were observed before treatment and treatment of 1 month, 3 months and 6 months after treatment respectively; the adverse events during the treatment were also recorded.
Results:
Compared before treatment, the O'Leary-Sant score (ICSI, ICPI), 24 h urination frequency, VAS and maximum bladder volume in the two groups were improved after 1, 3 months treatment and 6 months after treatment (all P<0.05). The scores of ICSI, ICPI, VAS and 24 h urination frequency in the observation group were significantly lower than those in the control group (P<0.05). The maximum bladder volume in the observation group was significantly higher than that in the control group (P<0.05). Six months after treatment, the total effective rate in the observation group was 87.5% (28/32), which was higher than 69.7% (23/33) in the control group (P<0.01). No significant adverse events occurred during the treatment.
Conclusion:
ENST could effectively relieve the clinical symptoms of IC/PBS, but its long-term efficacy needs further observation.
