Objective: Magnetic Resonance urography (MRU) enables one-step comprehensive morphological and functional imaging process of the urinary tract. The objective of the current study is to identify the role of static and dynamic MRU in evaluating the congenital urogenital anomalies in children. Design: A randomized controlled trial. Setting: Department of Pediatric and Radiology, Security Forces Hospital, Riyadh. Subjects: This study was conducted on 30 cases (17 females and 13 males) with different urinary tract abnormalities. Subjects were ranging in age from newborn to 9 years with a mean age of 24 months. Intervention: All children were assessed using ultrasonography, MRU, and excretory MRU (was available for 15 patients only). Main outcome measures: Static non-enhanced heavy T2W MRU was performed in 30 patients, in addition, the diuretic-enhanced excretory MRU was done for 15 patients using the same MR scanner. Results: MRU clearly afforded extra information to the results of further imaging modalities in 10 children in whom other imaging research studies were unable to provide the clear diagnosis. The confirmation supporting findings by MRU in the remaining 20 children also were beneficial in establishing the eventual diagnosis. However, the findings of MRU were unexclusive in 5 children. Conclusion: MRU might turn into the favored imaging modality in duplex renal anomalies and ureteral ectopia and might be adopted to interpret any discordant outcomes of traditional imaging techniques.
