Multicenter Study
Results of Sacral Neuromodulation Therapy for Urinary Voiding Dysfunction: Five-Year Experience of a Retrospective, Multicenter Study in China.
This five-year, retrospective, multicenter study evaluated the long-term safety and efficiency of sacral neuromodulation (SNM) in Chinese patients with urinary voiding dysfunction. ⋯ SNM appears effective in the long term, with a total IPG implantation rate of approximately 57% (ranging between 42.5 and 72.4% depending on indication). Interstitial cystitis/bladder pain syndrome appear to be the best indication for stage I testing. Chinese neurogenic bladder patients are most inclined to choose SNM. SNM is relatively safe, with low postoperation adverse events of 16.1% and reoperation rate of 3.2% during the follow-up period.

High-frequency (kHz) stimulation of preganglionic pelvic nerve afferents can inhibit voiding in both anesthetized and conscious rats. The afferents travel via the S1 sacral nerve root, which is easier to access than the distal pelvic nerve fibers within the abdominal cavity. We therefore investigated whether voiding could be inhibited by high-frequency stimulation at S1 and how this compared to distal pelvic nerve stimulation. ⋯ The authors reported no conflict of interest.

Randomized Controlled Trial
Safety, Feasibility, and Efficacy of Transcutaneous Tibial Nerve Stimulation in Acute Spinal Cord Injury Neurogenic Bladder: A Randomized Control Pilot Trial.
We investigated whether transcutaneous tibial nerve stimulation (TTNS) in acute spinal cord injury was safe and feasible, and could achieve neuromodulation and improve cystometrogram parameters during acute inpatient rehabilitation. ⋯ TTNS is a safe and feasible modality that can be performed during inpatient rehabilitation of acute traumatic spinal cord injury. Bladder capacity and episodes of detrusor-sphincter dyssynergia significantly worsened in the control group and did not significantly change in the TTNS group, suggesting that TTNS can alter the course of neurogenic bladder via neuromodulation.

Gastric electrical stimulation (GES) is a technology that uses neurostimulation for the modulation of gastric activity. In clinical practice, the most commonly encountered form of GES is high frequency GES. GES devices are typically used for the treatment of refractory gastroparesis, although they have also been investigated for obesity management and the treatment of refractory gastroesophageal reflux disease. Just as many patients with chronic diseases require surgery, patients with an implanted GES device may encounter the need for periprocedural care. Therefore, the purpose of this review is to address the special needs of patients with an implanted GES device. ⋯ Available data suggests GES is a technology with increasing prevalence. When patients with an implanted GES device present for periprocedural care, the anesthesia staff must consider the device when planning for the procedure. Topics addressed include general anesthetic considerations, nerve localization, radiation exposure, electrocautery, diathermy, emergency external defibrillation, and MRI compatibility.
