[Urologic impact of Crohn disease].

Presentation of two cases of Crohn's disease seen in our Service in which the urological symptoms were of special relevance. One patient presented clinically with a picture of anaemic gross haematuria. The other one, was a patient already diagnosed with Crohn's disease who developed an enterovesical fistula in spite of receiving medical treatment. Both cases were resolved surgically. The clinical aspects, natural history and treatment of this uncommon form of urinary tract involvement are discussed.
