The phenomenon of postural increases in urethral tone in patients with neuropathic bladder dysfunction has been investigated and, using the technique of simulated alterations in posture, a humoral response of urethral smooth muscle has been demonstrated. Serial measurements of circulating catecholamines have shown that a close correlation exists between the contraction of urethral smooth muscle and the variations in circulating catecholamines brought about as part of cardiovascular homeostasis. Identical urethral responses have been recorded in a group of neurologically intact patients who have urethral outflow obstruction, and it is speculated that these patients may have an occult urethral neuropathy.
对神经性膀胱功能障碍患者尿道张力随体位增加的现象进行了研究，采用模拟体位改变的技术，已证实尿道平滑肌存在体液反应。对循环儿茶酚胺的系列测量表明，尿道平滑肌的收缩与作为心血管稳态一部分的循环儿茶酚胺变化之间存在密切相关性。在一组患有尿道流出道梗阻的神经功能正常的患者中也记录到了相同的尿道反应，推测这些患者可能存在隐匿性尿道神经病变。
