Syncope is a symptom which is a transient loss of consciousness and very common in society and is one of the most important referral causes to emergency services. Micturition syncope (MS) appears as a rare cause of neurally-mediated syncope. MS is caused by reflex which results with vasodilatation and bradycardia, like defecation syncope. In the clinical setting, the MS is presented with transient loss of consciousness during supine position or micturition following after a sleep period mostly in otherwise healthy men. It is a reflex state in which standing triggers vasodilatation and bradicardia. MS covers 2-8% of all syncopes. There is still no consensus about treatment and outcome of MS. In this article two male patients with MS are presented. With these two cases, we aimed to give detailed information about micturition syncope which is a rare type of syncope.
