This clinical trial aims to find out if early electroacupuncture (EA) helps people recover the ability to control urination and is safe after surgery to remove the prostate gland for prostate cancer (radical prostatectomy).

Participants are people aged 18 to 80 with localized prostate cancer who have had radical prostatectomy and are in good physical condition (ECOG score 0-1, meaning they can manage daily activities well).

It will answer two key questions:

Does early EA make more people fully control their urination 3 months after prostate surgery? How does early EA affect urination control and safety at 1, 6, and 12 months after surgery? Researchers will compare two groups: one getting EA and the other getting a fake version (sham EA ) to see if EA works better.

Participants will start treatment 1 week after surgery, getting EA or sham EA 3 times a week for 6 weeks, 20 minutes each time. They will also complete tests to check urination control and fill out surveys about their urination, quality of life, and symptoms at different times. Their safety will be watched closely too.

Prostate cancer (PCa) is the most commonly diagnosed malignancy and the second leading cause of cancer-related death among men worldwide, significantly impacting both physical and psychological health. Radical prostatectomy (RP) remains the gold standard for treating localized prostate cancer, with three primary goals: oncologic control, recovery of urinary continence, and preservation of sexual function. While advances in surgical techniques and pharmacotherapy have substantially improved cancer control outcomes, functional recovery-particularly regarding post-prostatectomy incontinence (PPI)-remains a major challenge. PPI primarily results from intraoperative damage to the bladder neck structure and surrounding nerves, compromising urinary control. Postoperative ischemia and scar adhesion may further exacerbate incontinence. Studies report PPI rates of 18%-55% at 3 months and 4%-31% at 1 year after RP. Electroacupuncture(EA), evolved from traditional manual acupuncture, augments the technique by applying controlled electrical currents. Evidence suggests that EA can deliver pulsed currents to stimulate muscles and nerves, inducing passive contractions of the pelvic floor muscles. It may also excite sympathetic nerves, inhibit parasympathetic activity, modulate detrusor contractility, enhance urethral sphincter function, and improve urethral closure-all of which may contribute to restoring urinary control.Given these potential benefits, along with its simplicity, low cost, and favorable safety profile, we hypothesize that early post-surgical EA-initiated immediately after RP-may promote urinary continence more effectively than delayed intervention after conservative treatments have failed. This approach aligns with both clinical needs and the traditional Chinese medicine principle of "preventive treatment."Based on the premise that early EA can accelerate the recovery of urinary continence after RP, we previously conducted an observational study. The results indicated that early EA was associated with higher rates of early complete continence recovery, shorter time to continence, and high patient satisfaction, with no reported adverse events.To further evaluate the efficacy and safety of early EA for PPI, we designed this randomized, single-blind, sham-controlled, multicenter trial. Patients undergoing robotic or laparoscopic RP will be assigned to either EA or sham EA, with intervention starting within one week post-surgery and lasting for six weeks. The study aims to assess efficacy and safety outcomes, thereby determining whether early EA facilitates urinary continence recovery in patients following RP.
