Heat-sensitive moxibustion combined with Xiangwu powder for erectile dysfunction with kidney deficiency and blood stasis: a randomized controlled trial.

OBJECTIVES: To observe the clinical efficacy of heat-sensitive moxibustion combined with Xiangwu powder in treating erectile dysfunction with kidney deficiency and blood stasis.

METHODS: A total of 80 patients with erectile dysfunction of kidney deficiency and blood stasis were randomly divided into a comprehensive group (40 cases, 1 case dropped out) and a Chinese herb group (40 cases, 2 cases dropped out). In the Chinese herb group, Xiangwu powder was applied orally, one dose per day. On the basis of the Chinese herb group, heat-sensitive moxibustion was applied after detecting the heat-sensitive points in the areas of Guanyuan (CV 4), Zhongji (CV 3), Qihai (CV 6) and bilateral Xuehai (SP 10), Sanyinjiao (SP 6) in the comprehensive group, once a day, 5 times a week. Both groups were treated for 4 weeks. The international index of erectile function-5 (IIEF-5) score, erectile hardness score (EHS), nocturnal penile tumescence and rigidity (NPTR) indexes (nocturnal penile erection frequency, total duration of penile erection, duration of penile head hardness ≥60%, duration of penile root hardness ≥60%, percentage change in penile head circumference, percentage change in penile root circumference), TCM syndrome score, and penile vascular function indexes (peak systolic velocity [PSV], end diastolic velocity [EDV], and resistance index [RI] of penile cavernosal artery) were compared in the patients of the two groups before and after treatment, and the clinical efficacy was evaluated.

RESULTS: After treatment, the IIEF-5 scores, EHS, PSV, RI, and NPTR indexes were increased compared with those before treatment ( P <0.01), while the TCM syndrome scores and EDV were decreased compared with those before treatment ( P <0.01) in the two groups.The IIEF-5 score, EHS, PSV, RI, and NPTR indexes in the comprehensive group were ascended compared with those in the Chinese herb group ( P <0.01), while the TCM syndrome score and EDV in the comprehensive group were lower than those in the traditional Chinese herb group ( P< 0.01). The total effective rate of the comprehensive group was 94.9% (37/39), which was higher than 78.9% (30/38, P <0.05) of the Chinese herb group.

CONCLUSIONS: The combination of heat-sensitive moxibustion and Xiangwu powder can effectively treat erectile dysfunction of kidney deficiency and blood stasis, improve patients' erectile function, enhance their erection hardness, and improve their penile vascular function and clinical symptoms.
