Abstract：Objective：To observe the clinical effect of two electroacupuncture schemes combined with infrared radiation for postoperative urinary retention. Methods： A total of 90 patients with postoperative urinary retention were divided into the control group， the treatment group A and the treatment group B， with 30 cases in each group. The control group received infrared radiation therapy，the treatment group A received electroacupuncture (high- frequency) and infrared radiation therapy， and the treatment group B received electroacupuncture (low-frequency) and infrared radiation therapy. The clinical effects of the three groups were evaluated， and the urination status and urodynamic indicators were compared in the three groups. Results：The total effective rates in the treatment group A and the treatment group B were higher than that in the control group (P＜0.05)，and the total effective rate in the treatment group B was higher than that in the treatment group A (P＜0.05). After treatment， the scores of the first urination time and urination difficulty in the treatment group A and the treatment group B were lower than those in the control group， and the first urination volume and 2- hour urination volume were higher than those in the control group (P＜0.05). The scores of the first urination time and urination difficulty in the treatment group B were lower than those in the treatment group A，and the first urination volume and 2-hour urination volume after treatment were higher than those in the treatment group A (P＜0.05). After treatment， the bladder volume，average urine flow rates，detrusor pressure，and maximum urine flow rates in the three groups were all increased when compared with those before treatment (P＜0.05)；the bladder volume，average urine flow rates， detrusor pressure， and maximum urine flow rates in the treatment group A and the treatment group B were higher than those in the control group (P＜0.05)，and all indicators in the treatment group B were higher than those in the treatment group A (P＜0.05). Conclusion： Electroacupuncture combined with infrared radiation treatment for postoperative urinary retention can enhance the curative effect， promote the improvement of urination and urodynamic indicators， and low- frequency electroacupuncture is more effective than high-frequency electroacupuncture.
