The dog is unable to void until funnelling of the bladder neck occurs, even when the bladder is stressed with a large volume and with parasympathomimetic drugs. Nil or very little pressure rise occurs just prior to micturition. Well-coordinated voiding is associated with simultaneous electrical activity in either the upper urethra and bladder neck or these two areas plus the fundus, with predominance of electrical activity (frequency and amplitude) in the bladder neck in both circumstances. In cooordinate electrical activity is seen in bladder fundus, bladder neck, and upper urethra with incoordinate voiding.
在膀胱颈漏斗形成之前，狗无法排尿，即使膀胱因大量尿液和拟副交感神经药物而处于应激状态。排尿前几乎没有或仅有很小的压力升高。协调良好的排尿与尿道上段和膀胱颈或这两个区域加膀胱底部的同步电活动相关，在这两种情况下膀胱颈的电活动（频率和幅度）占主导。不协调排尿时，膀胱底部、膀胱颈和尿道上段可见不协调的电活动。
