13 clinical trials were evaluated to determine the efficacy of Acupuncture for nocturnal enuresis (NE) in children.  12 out of the 13 studies reported that Acupuncture as part of a complete Traditional Chinese Medicine (TCM) package to better than alarm therapy, which is the gold-standard in Western medicine for NE. The researcher also found that electro-acupuncture increases treatment outcomes, and that Acupuncture alone did not work as well when not used in a combined TCM approach. Researchers state that Acupuncture is effective at treating NE by influencing the spinal micturition centers and parasympathetic innervation of the urinary tract.
