A follow-up study was performed on 10 patients with micturition syncope 5-15 years after their initial attack. Three patients had died of cardiac or pulmonary diseases (at age 61, 69 and 82 years). One had developed focal motor epilepsy which was considered to be unrelated to his previous attack of micturition syncope. One (age 60) developed a hemianopsia in connection with his micturition syncope. Only one patient had had a new attack of micturition syncope which had occurred during a febrile illness. Two often sit down prophylactically during micturition. It is concluded that micturition syncope most often is a benign phenomenon which should be distinguished from epilepsy. The patient may be advised to sit down during micturition, especially at night, but treatment is otherwise not necessary.
