Urografia Por Tomografia Computada Multicorte (Urotac): Estudio Descriptivo Utilizando La Técnica De "Split Bolus"

Abstract

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.

Computed Tomography With 3d Reconstruction for The Diagnosis of Traumatic Urethral Injuries

“…Currently, multi-slice computed tomography scanners perform highresolution images with three-dimensional reconstructions; so Computed Tomography Urography is the method preferred for evaluating the urinary tract, replacing the traditional retrograde urography, in patients with urine bleeding and risk factors for developing cancer [5]. Although the Computed Tomography Urography allows us to evaluate the collecting systems, ureters and bladder, but it is not possible to study the entire urethra with this method, since it has not been possible to replace…”
