目的：本研究的目的是评估膀胱肛门反射（BAR）的潜伏期在无症状的妇女，并确定反射的途径，使用选择性麻醉和神经肌肉阻滞。方法：尿失禁、排尿功能障碍和盆腔器官脱垂是妇女常见的问题。盆腔神经功能的评估往往会增加这些妇女的临床评估。尿道-肛门和阴蒂-肛门反射测试已被报道为评估神经源性疾病患者的方法。膀胱-肛门反射也可获得，但以前文献中没有报道。招募了22名受试者和2名患者用于评价BAR。结果：这项研究使我们能够估计BAR潜伏期和阈值的参考范围。我们将这些参考范围的上限定义为高于其各自平均值的两个标准差。对于BAR延迟，参考范围的上限为91毫秒。任何高于此限值的延迟值都应视为异常。BAR阈值参考范围的上限为37.7 mA。较低的阈值被认为没有临床意义，因为在这个无症状的正常人群中存在几个低的感觉阈值。结论：BAR可用于无症状女性，与已知的下尿路解剖结构和神经支配一致。
Aims: The purposes of this study were to evaluate the bladder-anal reflex (BAR) latency in asymptomatic women and determine the pathway of the reflex using selective anesthesia and neuromuscular block. Methods: Urinary incontinence, voiding dysfunction, and pelvic organ prolapse are common problems in women. Evaluation of pelvic nerve function often augments the clinical assessment of these women. Urethral-anal and clitoral-anal reflex testing have been reported as methodologies to assess patients with neurogenic disorders. A bladder-anal reflex is also obtainable but has not been reported previously in the literature. Twenty-two subjects and two patients were recruited for evaluation of the BAR. Results: This study has allowed us to estimate reference ranges for BAR latency and threshold. We defined the upper limit of these reference ranges as two standard deviations above their respective means. For the BAR latency, the upper limit of the reference range is 91 msec. Any latency value above this limit should be considered abnormal. The upper limit for the BAR threshold reference range is 37.7 mA. Lower thresholds are not thought to be clinically meaningful due to the presence of several low sensory thresholds in this asymptomatic normal population. Conclusions: The BAR was obtainable in asymptomatic women and compatible with known anatomy and innervation of the lower urinary tract.
