title: [Borderline between the normal and the pathological in the radiological diagnosis of the posterior male urethra and female urethra in childhood].
abstract: The authors, with the support of a large case report, point out several varieties of the standard urethrography of a normal urethra and the correlations between macroscopic anatomy, radiologic anatomy and physiology. They stress the importance of a good knowledge of the urethral anatomy and of the urethrographic physiology in order to avoid considering as pathologic a really normal radiologic finding.
