Objective: Computed Tomography Urography (CTU) is an imaging method used to assess the kidneys, ureters, and bladder in the excretory phase by computed tomography (CT) with intravenous contrast media (IVCM). Our aim is to compare the five different methods performed for patient preparation prior to CTU, and to demonstrate their superiorities and disadvantages compared to each other.

Materials and Methods: A total of 100 patients who underwent CTU scans with an indication as a result of their examinations were included in our study. These cases were randomly divided into 5 groups of 20. Water was applied to the first group. Saline was administered to the second group. In the third group, 0.1 mg/kg furosemide was administered intravenously following a 250 mL saline. Intravenous furosemide was administered to the fourth group. Intravenous furosemide was administered to the fifth group after they received water. Ureters were compared with each other according to the degree of opacification in proximal, medial, and distal segments in standard CTU.

Results: By comparing the groups in pairs; there was a significant difference between Group II and the other four groups for the proximal ureter segment, and between Group II and Group III and IV for the medial and distal ureter segments (P<0.05).

Conclusion: We believe that intravenous saline didn’t increase ureter opacification compared to the other groups due to different patient populations and hydration conditions, instead saline increased ureter contractions and homogeneous diuresis related to furosemide.
