[Effect of electroacupuncture preconditioning combined with induced urination on urinary retention after milligan-morgan hemorrhoidectomy].

OBJECTIVE: To investigate the effect of electroacupuncture preconditioning combined with induced urination on urinary retention after milligan-morgan hemorrhoidectomy. METHODS: Eighty patients with mixed hemorrhoids were randomly divided into an electroacupuncture group and a routine group, 40 cases in each group. Anesthesia at Yaoshu (GV 2) was given in the two groups. In the electroacupuncture group, electroacupuncture at Zhongji (CV 3)，Guanyuan (CV 4)，Pangguangshu (BL 28) and Sanyinjiao (SP 6) was applied with tolerant intensity for 30 min before operation, 2 Hz/100 Hz in frequency. After operation, induced urination was given, namely hot compress of bladder area and sound of hearing water. In the routine group，induced urination was given after operation. The score of the first urination waiting time, the distension of lower abdomen on the evening of the postoperative, the first time urinary volume and incidence of urinary retention were compared between the two groups. RESULTS: <0.05). CONCLUSION: Electroacupuncture preconditioning combined with induced urination can effectively prevent the incidence of urinary retention after milligan-morgan hemorrhoidectomy.
