Magnetic resonance urography in the evaluation of obstructive uropathy

Abstract

Purpose: The purpose of this study was to study the utility of magnetic resonance urography (MRU) in the evaluation of obstructive urological diseases in comparison to intravenous urography (IVU). Materials and Methods: The study was carried out over a period of 2 years. A total of 55 patients were included in this study with ages between 14 and 70 years (average age 37 years). The patients were selected on the basis of ultrasonographic findings of hydronephrosis. The patients were subjected to IVU followed by static and dynamic MRU. The results obtained were compared and the inferences drawn thereof. Results and Conclusions: MRU has high sensitivity in the diagnosis of urinary tract obstruction, detecting the level of obstruction and acts as an aid in the diagnosis of obstructive uropathy, thus showing promising results. MRU is safer than IVU due to avoidance of iodinated contrast material and could also be done without using contrast material so having less contrast related events.
