Multislice computed tomography provides high spatial and temporal resolution images in addition to high quality multiplanar and three-dimensional reconstructions. As a result of this diagnostic efficacy, the Computed Tomography Urography (Uro-CT) has become the technique of choice for evaluating the urinary tract, virtually replacing the traditional urography examination. At Padre Hurtado Hospital, Santiago, Chile, we conducted a retrospective analysis to review our experience with Uro-CT scanning and split bolus technique, which has the potential to yield a synchronous nephrographic and excretory phase of the urinary system, thus reducing radiation dose for patients, number of images and costs generated by MDCT urography. A series of 31 cases is presented, along with description of techniques applied as well as study main findings.
