title: Asymptomatic cystic fibrosis diagnosed in an adult evaluated for hematuria.
abstract: We report a case of cystic fibrosis in an asymptomatic man evaluated for hematuria with infertility. The ever-broadening spectrum of atypical adult presentations of cystic fibrosis should prompt physicians to have a lower threshold for ordering genetic screening for cystic fibrosis transmembrane regulator (CFTR) gene mutations.
