RESUMO
Objective To evaluate the clinical efficacy of nerve-related acupoints electrical stimulation in preventing urinary retention after hemorrhoid surgery. Method Ninety-seven patients were randomized into two groups: the treatment group received nerve-related acupoints electrical stimulation 1 h after Milligan-Morgan hemorrhoidectomy for mixed hemorrhoids, while the control group was taken as a blank control. The incidence of postoperative urinary retention, residual urine volume after the first urination, general urinary condition score, and satisfaction evaluation were compared between the two groups. Result The incidence of postoperative urinary retention and residual urine volume after the first urinary were lower, and the general urination condition and satisfaction evaluation were higher in the treatment group compared to those in the control group. Conclusion Nerve-related acupoints electrical stimulation can prevent and reduce the adverse reactions such as urinary retention after hemorrhoidectomy, and it can effectively protect the bladder function and improve the prognosis.
