[The Laferma reflux family, a case of multiple familial reflux]. 
We substantiate that five of total seven examined members of a family including the mother showed a reflux disease.  Two of them had a monolateral, three a bilateral, two a vesicoureteral and three a vesicorenal reflux.  Three of the examined members suffered from enuresis nocturna.  All of the reflux-positive members of the family endoscopically showed gaping ostia of the ureter at the reflux-positive side.  We found no criteria for an intravesical obstruction.  All reflux-positive members showed a low-pressure reflux.  Interestingly, only the female members exhibited a reflux.  We don't know whether this case of an increased incidence of reflux disease within one family will represent a known hereditary pattern.
