Kidney Lower Pole Pelvicaliceal Anatomy: Comparative Analysis Between Intravenous Urogram and Three-Dimensional Helical Computed Tomography

摘要

Conclusion: Although 3D-HCT is more precise to study calculus location, tumors, and vessels, IVU was also demonstrated to be as precise as 3D-HCT for studying the lower pole spatial anatomy. We did not observe any statistically significant difference in the measurements of IPA, ID, and CD obtained using 3D-HCT when compared with those obtained using IVU. Therefore, 3D-HCT does not present any advantage over IVU in the evaluation of lower pole caliceal anatomy.
