Efficacy of Acupuncture for Postoperative Urinary Retention Following Radical Hysterectomy for Cervical Cancer

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.
