Two brothers with congenital bulbar urethral stricture: case report of a very rare condition.

Congenital urethral stricture is rare. It has been reported in only four sets of brothers. We report the fifth set of brothers. Cases of two brothers aged 23 and 18 years old diagnosed with low urinary tract symptoms are presented. We diagnosed an apparently congenital urethral stricture in both brothers. Internal urethrotomy was performed in both cases. Both are asymptomatic after 24 and 20 months of follow-up. Congenital urethral strictures are probably more frequent than we think. We suggest that a congenital origin should be considered if there is no history of infections or trauma.
