An interventional study of Acupuncture and Sham acupuncture in Postoperative Urinary Retention (POUR), sponsored by Obstetrics & Gynecology Hospital of Fudan University. Not yet recruiting. Open to female participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-07-17.
Sponsored by Obstetrics & Gynecology Hospital of Fudan University · Not applicable, Interventional, and Treatment
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:
Exclusion Criteria:
Procedure: Acupuncture
Procedure: Sham acupuncture
Participants receive acupuncture treatment in addition to intermittent catheterization and an α-blocker (e.g., tamsulosin). Acupoints selected: Zhongji (CV3), Yinlingquan (SP9), Sanyinjiao (SP6), Ciliao (BL32), Zhongliao (BL33), Pangguangshu (BL28), Zhibian (BL54). Treatment lasts for 2 weeks.
Participants receive sham acupuncture treatment in addition to intermittent catheterization and an α-blocker (e.g., tamsulosin). The same acupoints as in the acupuncture group are selected. Sham acupuncture method: using a placebo needle device with a blunt tip that gives the sensation of skin penetration without actually piercing the skin. Treatment lasts for 2 weeks.
Post-void residual urine volume (PVR)
Measured via B-mode ultrasound after spontaneous voiding following catheter removal and ingestion of approximately 1000 ml of water.
Time frame: pre-intervention，immediately after the intervention
Voiding diary
Standardized recording of urinary frequency, volume, and symptom patterns over a defined period.
Time frame: pre-intervention，immediately after the intervention
Maximum urinary flow rate (Qmax)
Peak flow rate during voiding, obtained via urodynamic assessment.
Time frame: pre-intervention，immediately after the intervention
First desire to void (FDV)
Volume of urine in the bladder at the initial sensation of needing to urinate, obtained via urodynamic assessment.
Time frame: pre-intervention，immediately after the intervention
International Consultation on Incontinence Questionnaire - Female Lower Urinary Tract Symptoms Long Form
International Consultation on Incontinence Questionnaire for Female Lower Urinary Tract Symptoms (long form), used to quantify symptom burden and quality of life impact. The minimum value of the questionnaire is 0 and the maximum value is 69. Higher scores mean a worse outcome.
Time frame: pre-intervention，immediately after the intervention
