This is a prospective, blinded, single-center, randomized controlled trial. We will include 76 patients with postoperative urinary retention (POUR) after radical hysterectomy for cervical cancer who have a clear diagnosis and meet the screening criteria as the research object. They will be randomly divided into the transcutaneous electrical acupoint stimulation（TEAS）group and the sham TEAS group according to a 1:1 ratio. Each group consists of 38 patients, and all patients will be required to sign a written informed consent form. The TEAS group will be treated with TEAS based on conventional treatment, and the sham TEAS group will be treated with shamTEAS based on conventional treatment. The main outcomes will be the changes in post-void residual (PVR) volume; secondary indicators will include the response rate of participants with successful urinary catheter removal after intervention, assessment of urinary tract infection (UTI), and patient quality of life assessment according to the EORTC QLQ-C30 scale. The participants will also be evaluated with expectations, blind evaluation, compliance evaluation, and safety evaluation to preliminarily evaluate the effect of TEAS for postoperative urinary retention after radical hysterectomy for cervical cancer.
