[Familial vesico-ureteral reflux and familial urinary tract infection (author's transl)].

In 6 families several members had vesico-ureteral reflux and/or recurrent urinary tract infections. From the analysis of the case reports the following tentative conclusions could be drawn: Familial reflux may be caused. 1. by primary insufficiency of the vesico-ureteral junction. 2. possibly by secondary changes consequent to a familial tendency to recurrent urinary tract infections.
