The bladder cooling test, which consists of rapid infusion of 0 to 8C saline into the bladder with simultaneous pressure measurement, was performed in 50 neurologically intact infants and children 6 months to 13 years old. The patients were referred for urodynamic investigation because of various disorders of the lower urinary tract. A positive bladder cooling test was defined as a sustained reflex detrusor contraction of about the same magnitude as the micturition contraction. The test was positive during the first 4 years of life but typically negative in children older than 5 years. These findings indicate that a positive bladder cooling test is an infant reflex response that, with the maturation of the central nervous system, becomes suppressed by descending signals from higher centers.
膀胱冷却试验包括向膀胱快速输注0至8摄氏度的生理盐水并同时测量压力，该试验在50名6个月至13岁神经系统正常的婴幼儿及儿童中进行。这些患者因各种下尿路疾病而接受尿动力学检查。阳性膀胱冷却试验定义为持续的逼尿肌反射性收缩，其强度与排尿收缩大致相同。该试验在生命的最初4年呈阳性，但在5岁以上儿童中通常为阴性。这些发现表明，阳性膀胱冷却试验是一种婴儿反射反应，随着中枢神经系统的成熟，该反应会被来自高级中枢的下行信号所抑制。
