From an analysis of 202 patients and a careful literature analysis we conclude that pathological urethral instability should be differentiated from physiological urethral pressure variations by the following criteria: a pronounced amplitude of at least one third of the maximum urethral pressure variations by the following criteria: a pronounced amplitude of at least one third of the maximum urethral closure pressure (usually > 25 cm H2O), a short duration (1-5 s), a simultaneous inhibition of the electromyographic activity in urethral and (or) anal sphincter, and the occurrence of the phenomena starting at the beginning of bladder filling (100 ml).
通过对202例患者的分析以及仔细的文献分析,我们得出结论:病理性尿道不稳定应根据以下标准与生理性尿道压力变化相鉴别:最大尿道压力变化幅度至少有三分之一较为显著(以下标准:最大尿道闭合压力至少有三分之一的显著幅度,通常>25 cm H₂O),持续时间短(1 - 5秒),尿道和(或)肛门括约肌肌电活动同时受到抑制,且这些现象在膀胱充盈开始时(100 ml)出现。
