[Ectopia of the right ureter as the cause of a cystic abdominal space-occupying lesion].

Ureteral ectopias, which mostly occur in ureteral duplications, become noticeable in women quite early by characteristic clinical signs (dribble, or urinary incontinence). In males, it is usually only a stenosis-conditioned dilatation of the ureter that results in an uncharacter-istic pattern of complaints. The article presents the clinical pattern of signs and the x-ray findings in a man of 42 year of age, who had not reported any complaints until then, with an excessive dilatation of an extopically discharging single ureter.
