The sacral nerve stimulator, commonly known as the “bladder pacemaker”, is a permanent electrode implanted through the sacral 3 nerve orifice and an electrical stimulator implanted in the ipsilateral gluteal area. The stimulator continuously sends electrical pulses in square waves to provide continuous electrical stimulation or modulation of the sacral 3 nerve to improve the urinary function of the bladder urethra. Indications for bladder pacemakers include: Urge incontinence: involuntary urine leakage accompanied by a sudden, strong urge to urinate. Urinary frequency and urgency syndrome: uncontrollable urgency to urinate, with low and frequent urine output, even every 15 minutes. Non-obstructive urinary retention: difficulty in urination, the bladder cannot be emptied and there is still urine left in the bladder. Interstitial cystitis: painful holding, painful urination, severe urinary frequency and urgency. Chronic pelvic pain: pain around the vagina, urethra and perineum, along with frequent urinary urgency. What kind of patients are suitable for bladder pacemaker implantation? Patients with chronic voiding dysfunction can be treated with a bladder pacemaker when physical therapy or medication is not effective in controlling symptoms or when the patient cannot tolerate these treatments. What is the efficacy and safety of bladder pacemakers? Since the 1990s, bladder pacemakers have enabled tens of thousands of patients to regain normal urinary function and start a new life, with long-term stable results. Bladder pacemaker therapy is a minimally invasive and safe procedure that does not damage body tissues and allows for non-invasive parameters to be adjusted outside the body for optimal results depending on the patient’s condition. How do you ensure the efficacy of a bladder pacemaker? When the physician determines that the patient is a candidate for bladder pacemaker therapy, a 2-week experiential treatment is performed and the entire system is implanted after the patient’s symptoms are confirmed to be under control.
