Responsible centers Oslo University Hospital, Aker. Division of Radiology and Nuclear medicine.~Study type: Prospective clinical trial~Study design: One sample paired proportion, non-inferiority study with a 7.5% non-inferiority limit.~Investigational product: One phase nephrographic CT (experimental arm) vs. Four-phase CT (control arm)~Objective:The primary objective is to evaluate whether one-phase nephrographic CT (experimental) is sufficient to detect urothelial cell carcinoma in patients with asymptomatic macroscopic hematuria compared to the traditional four-phase CT (control).~Primary endpoints: The difference in accuracy between the experimental- and control arm.~there will also be a secondary reading in order to asses interobserver variability for both the experimental and the control arm~Sample size: 250 patients
The primary objective is to evaluate whether one-phase nephrographic CT (experimental) is sufficient to detect urothelial cell carcinoma in patients with hematuria compared to the traditional four-phase CT (control).
