[Uroradiology]

Abstract

Radiology of the urinary tract has a great place in evaluating voiding dysfunction. The role of the radiologist is not limited to diagnosis of the sequelae of voiding dysfunction but he must provide information about causes, mechanisms and helps to provide a more accurate diagnosis. Projectional radiography (excretory urography, voiding cysto-urethrography) is still the best method of evaluation in spite of development of new imaging techniques (ultrasonography, computerized axial tomography, magnetic resonance imaging). Radiodynamic examination of the lower urinary tract is the best method of choice to study the complex functional problems involving those structures.
