Clinical treatment of chronic nonbacterial prostatitis of kidney-yang deficiency type by acupuncture of Sanhuang points / 针刺研究

ABSTRACT

OBJECTIVE: To observe the clinical effect of acupuncture stimulation of Sanhuang points in the treatment of chronic nonbacterial prostatitis (CNP) of kidney-yang deficiency type. METHODS: A total of 60 CNP outpatients were equally randomized into medication(control) group and acupuncture plus medication (acupuncture) group. Patients of the control group were ordered to take Tamsulosin (0.2 mg/d) for successive 8 weeks. On the basis of medication treatment, for patients of the acupuncture group, bilateral Sanhuang points including Tianhuang-fu Point (Shenguan), Dihuang Point and Renhuang Point (at the lower leg) were needled with filiform needles which were manipulated for a while till Deqi, followed by retaining the needles for 30 min. The treatment was conducted once daily for successive 8 weeks. The therapeutic effect was evaluated in reference to the "Criteria for Diagnosis and Therapeutic Effect Evaluation of Syndromes/Diseases of Traditional Chinese Medicine". The National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) scores were used to assess the severity of chronic prostatitis. Routine examination of the leukocyte count in the prostatic fluid was performed before and after the treatment. RESULTS: Of the two 30 cases of the control and acupuncture groups, 9 and 19 were cured, 14 and 10 experienced improvement, and 7 and 1 failed in the treatment, with the effective rates being 76.67% and 96.67%, respectively. The effective rate of the acupuncture plus medication was significantly higher than that of the medication (P<0.05). After the treatment, the scores of NIH-CPSI and white blood cell counts in the prostatic fluid in both groups were significantly decreased in comparison with their own pre-treatment (P<0.05). The therapeutic effect of acupuncture plus medication was significantly superior to that of the medication alone in reducing the NIH-CPSI symptom score and the number of leukocytes in the prostatic fluid (P<0.05). CONCLUSION: Acupuncture at Sanhuang points is effective in improving symptoms of CNP patients of kidney-yang deficiency type, and the therapeutic effect of acupuncture plus medication is superior to that of medication alone.
