Objective: to observe the clinical effect of electroacupuncture on postpartum urinary retention (PPUR) through a randomized controlled study. Methods: seventy-two PPUR puerperae who met the inclusion criteria were divided into the observation group (electroacupuncture at Ciliao (BL32) and Zhongliao (BL33) group) and the control group (sham acupuncture group) according to the random number table method, with 36 cases in each. Urine catheters were retained. After 3 days of treatment, the therapeutic effect of PPUR was compared between the two groups. Results: in the observation group, the first urination time was significantly earlier than that in the control group, the first urination volume was significantly more than that in the control group, the bladder residual urine volume was significantly less than that in the control group, and the urinary infection was significantly less than that in the control group, the differences were statistically significant (all P < 0.001). Compared with the control group, there were statistically significant differences in catheter removal, independent urination, cured cases, effective cases, ineffective cases, and total effective cases in the observation group (all P < 0.05). Conclusion: the therapeutic value of electroacupuncture at BL32 and BL33 for primiparae with PPUR is significantly obvious. This therapy is worthy of clinical promotion.
