Objective: Detailed review of the CT urography technique, evaluation of the advantages and disadvantages of the existing protocols, improvement of the technique, and current indications of the study to provide an algorithm that facilitates the selection of the most efficient protocol based on evidence. Methods: This article reviews the most relevant publications in the literature, using the Pubmed database on the CT urography protocol, emphasizing single bolus and split bolus techniques, current recommendations, and study indications. Conclusions: Both the single bolus and split bolus techniques demonstrate effective results in detecting malignant lesions in the upper urinary tract. However, the split bolus technique is particularly advantageous due to its lower radiation dose, making it preferable for patients under 60 years of age and without risk factors. For scenarios involving various benign pathologies affecting the urinary tract, the split bolus technique emerges as the optimal choice. Additionally, the adjunct use of furosemide proves to be the most effective method for enhancing distension and opacification of the upper urinary tract.
