Micturition Desire-Relaxation Training Device for Lower Urinary Tract Dysfunction in Children

Urine storage and voiding are fundamental physiological processes. In clinical settings, many cases of lower urinary tract dysfunction (LUTD) are closely associated with abnormal conditioned reflexes formed in the central nervous system during the urine storage or voiding phases. Relaxation, as a core physiological and psychological state, has been shown to promote effective urine storage and facilitate smooth voiding. By repeatedly training individuals to establish a new conditioned reflex linking the sensation of urinary urgency with a state of relaxation, it may be possible to improve bladder storage capacity and voiding function. Based on this concept, the investigators have developed the world's first Micturition Desire-Relaxation Training Device (Chinese Patent No.: ZL 2020 1 0397789.4). This study aims to evaluate the clinical efficacy of this device in treating LUTD in children.
