Objective To investigate the effect of Thunder-fire Moxibustion on nocturnal urinary symptoms in patients with benign prostatic hyperplasia (BPH). Methods According to hospitalized number from January to December 2018, 61 BPH patients with frequent nocturnal urination were divided into control group (treated with routine nursing and drug therapy) and observation group, where the Thunder-fire moxibustion was used once a day for one course of treatment every 10 days for 3 courses of treatment. The effect was observed by looking into the number of nocturnal urine and the prostate symptoms. Result After the treatment, the number of nocturnal urine in the observation group was smaller than that in the control group, and the IPSS score in the observation group was lower than that in the control group (P ＜0.001), and no adverse reactions were observed. Conclusion The Thunder-fire Moxibustion combined with drug therapy can improve nocturnal urinary symptoms of benign prostatic hyperplasia in a safe way.
