Postoperative Urinary Retention (POUR)

The goal of this clinical trial is to learn if acupuncture works to treat postoperative urinary retention in patients who have undergone radical hysterectomy for cervical cancer. The main question it aims to answer is: Does acupuncture lower the volume of post-void residual in participants who need to use intermittent catheterization to assist with voiding after radical hysterectomy for cervical cancer? Researchers will compare acupuncture to sham acupuncture (non-penetrating needles: using placebo needles with a blunt tip that gives the sensation of skin penetration without actually piercing the skin) to see if acupuncture works to treat postoperative urinary retention. Participants will: 1. Receive acupuncture or sham acupuncture or tamsulosin for 2 weeks. 2. Visit the clinic before and after treatment for checkups and tests. 3. Keep a voiding diary and record the volume of post-void residual and the number of times they use intermittent catheterization.

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.

This is a prospective, blinded, single-center, randomized controlled trial. Investigators will include 208 patients with postoperative urinary retention (POUR) after radical hysterectomy for cervical cancer who have a clear diagnosis and meet the screening criteria. Participants will be randomly divided into the electroacupuncture（EA）group and the sham EA group according to a 1:1 ratio. Each group consists of 104 patients, and all participants will be required to sign a written informed consent form. The TEAS group will be treated with EA based on conventional treatment, and the shamEA group will be treated with sham EA based on conventional treatment. The main outcomes will be to calculate the proportion of patients who successfully removed the urinary catheter, and the secondary indicators will include the change in post-void residual (PVR) volume of the bladder, assessment of urinary tract infection (UTI), and quality of life assessment according to the EORTC QLQ-C30 scale. Evaluation of participant-reported expectations, blinding, compliance, and safety will also be conducted. All analyses will be conducted in accordance with the intention-to-treat principle.

The purpose of this research study is to determine if taking tamsulosin preoperatively decreases your chances of being discharged after surgery with a Foley catheter (flexible tube that drains urine from the bladder into a collection bag).
