Abstract
BACKGROUND:Stress urinary incontinence (SUI) is defined as involuntary leakage of urine from the external urethra due to increased abdominal pressure, for example, upon sneezing, coughing, or exercise. Acupuncture is an effective therapy for patients with SUI, although objective evidence of its benefits or mechanism of action is limited. Patients with SUI often harbor structural changes of pelvic floor, the parameters of which are measurable from various perspectives and in multiple dimensions, dynamically and comprehensively, through transperineal ultrasound (TPUS). The status of such changes may then be assessed following acupuncture procedures. In the present investigation, TPUS serves to gauge the immediate effects of acupuncture on pelvic floor structures in female patients with SUI. METHODS: This protocol calls for a prospective, randomized, controlled, and single-blinded study of 72 female patients with SUI, each randomly assigned as test or control group members. The test group is subjected to one-time acupuncture at the Zhongji (RN3) acupoint for a period of 10 min, whereas the control group undergoes sham acupuncture in the same manner. In both groups, TPUS imaging of pelvic floor is performed before, during, and immediately after acupuncture procedures. Bladder neck mobility (BND), urethral rotation angle (URA), retrovesical angle (RVA), lowest point of bladder (BN-S), and presence/absence of urethral funneling or bladder bulging are then recorded as outcome measures. DISCUSSION: Above efforts are intended to assess real-time pelvic floor structural changes in women undergoing acupuncture for SUI. The subsequent findings may help objectively document the efficacy of acupuncture in this setting and clarify its mechanism of action. TRIAL REGISTRATION: Registration with the Chinese Clinical Trial Registry (ChiCTR200041559) (http:// www.chictr.org.cn/edit.aspx?pid=64591&htm=4), was effective December 29, 2020. DATES OF STUDY: 12/19/2020 to 06/30/2022.
